There should be no category/tag prefixed to the rule title, such as "Accessibility - Image tags should have an alternate text attribute". and export it as an Excel, csv or xml. In part two of this SonarQube tutorial, we will demonstrate how to use the SonarQube Maven Plugin to integrate Java source code with the static code analysis capabilities of the tool. Application Security. Code Quality and Security for Java . The following parts are mandatory in RSPEC language-specification: Guidelines regarding COBOL, keywords and code are the same as for other rules. Automatically detect Bugs, Vulnerabilities and Code Smells with SonarSource's Javascript analysis. With SonarQube installed and configured and the administrative console up and active, the tool is ready to begin inspecting source code and reporting on a variety of SonarQube metrics. Examples: remove unused imports, replace tabulations by spaces, remove call to System.out.println() used for debugging purpose, ... EASY Note that latest released versions of the Java Analyzer are always compatible with the current LTS version of SonarQube. Before we start with the implementation of the rule itself, you need a little background. The flag to be used is a simple "// Noncompliant" trailing comment on the line of code where an issue should be raised. It provides lot of rules to scan multiple languages of your projects It provides a way to scan all the languages together which are present in one git repo. To save rules click on the "Permalinks" tab when viewing an existing profile. Since our rule targets method declarations, we only need to visit methods. The following screenshot shows how severity of a rule can be changed to info from minor. Compliant Solution - demonstrating how to fix the previous issues. Start by building the project using maven: Then, grab the jar file java-custom-rules-1.0-SNAPSHOT.jar from the target folder of the project, and move it to the extensions folder of your SonarQube instance, which will be located at $SONAR_HOME/extensions/plugins. Note that while verifying a rule, the verifier will collect lines marked as being Noncompliant, and verify that the rule raises the expected issues and only those issues. Gandalf - Why Program When Magic Rulez (WPWMR, p.42), “For a method having a single parameter, the types of its return value and its parameter should never be the same.”. 。 如果依赖的是dcits-java-custom-rules开发,那么不需要进行任何修改。 3.3 Rule开发 以下以teller9的不允许 Everything else is a Code Smell. Keeping this in consideration, how do you change rules in SonarQube? To use the RIPS SonarQube plugin within Java or PHP projects, you have to install the associated SonarQube default plugin for the language. Create a … When in doubt, ask yourself: "Is code that breaks this rule doing what the programmer probably intended?" The last remaining step is to test it directly with the SonarQube platform and try to analyse a project! For example, if you sample code used in your Unit Tests is having a dependency on Spring, add it there. Because the flagged lines do not comply with the rule. RIPS Plugin Setup The RIPS plugin for SonarQube is currently not in the SonarQube plugin repository. The remediation action might lead to an impact on the overall design of the application. Once your new rule is written, you can add it SonarQube: Login as an Quality Profile Administrator. Remove or refactor this useless "switch" statement. Technical Debt. Impact: Could the bug cause the application to crash or corrupt stored data? This visitor offers an easy approach to writing quick and simple rules, because it allows us to narrow the focus of our rule to a given set of Kinds to visit by subscribing to them. This part can be easily translated by a developer into examples of implementation/source code, if the recommendations are too abstract the developer will not be able to imagine the fix and decide whether to implement it. Moreover, violations considered as "bugs" by SonarQube were generally not fault-prone and, consequently, the SonarSource's Java analysis has a great coverage of well-established quality standards. That's why precisely configuring what to analyze for each project is a very important step. Then your logical choice may be to implement your own set of custom Java rules. Because we registered the rule to visit Method nodes, we know that every time the method is called, the tree parameter will be a org.sonar.plugins.java.api.tree.MethodTree (the interface tree associated with the METHOD kind). Your rule should now be visible (with all the other sample rules). This is for the benefit of users whose rule parameters are tuned to something other than the default values. You'll see (at least for Java projects ) links for all rules engines and one that includes all of them. In the code snippet below, it is important to note that the entry point of the plugin is provided as the  in the configuration of the sonar-packaging-maven plugin, using the fully qualified name of the java class MyJavaRulesPlugin. Other properties such as  and  can be freely modified. The main differences between vulnerabilities and hotspots are explained on the security-hotspots page. issue.type.BUG issue.type.VULNERABILITY issue.type.CODE_SMELL issue.type.SECURITY_HOTSPOT It starts with a copy of the title. Java. It is activated for project “Sample project for SonarQube”. Ask Yourself Whether - set of questions that the developer should ask herself/himself. See : https://github.com/SonarSource/sonar-custom-rules-examples/blob/master/java-custom-rules/pom.xml#L147. E.G. It means less maintenance for you, and benefit to others. Starting with the subject, such as "Files", will ensure that all rules applying to files will be grouped together. At the end of the review, the developer should be sure that in its context the implementation of this protection improves the overall application's security. Prior to running any rule, the SonarQube Java Analyzer parses a given Java code file and produces an equivalent data structure: the Syntax Tree. Our goal will be to add an extra rule! For potential-bug rules, it should make it explicit that a manual review is required. You can't modify an existing rule. This can be achieved using the special keywords 'sc' (start-column) and 'ec' (end-column) in the "Noncompliant" comment. Siva Reddy 4,919 views 22:11 What is SonarQube? From the symbol, it is then pretty easy to retrieve the type of its first parameter, as well as the return type (You may have to import org.sonar.plugins.java.api.semantic.Symbol.MethodSymbol and org.sonar.plugins.java.api.semantic.Type). Is it possible to create the rule for Java using the template that is available in SonarQube 6.0? Now that you've fleshed out the description, you should have a fairly clear idea of what type of rule this is, but to be explicit: Bug - Something that's wrong or potentially wrong. This document is an introduction to custom rule writing for the SonarQube Java Analyzer. Among the 202 rules defined for Java by SonarQube, only 25 can be considered to have relatively low fault-proneness. Code samples for COBOL should be in upper case. Vulnerability - Something that's wrong which impacts the application's security and therefore needs a fix. By looking back at our test file, it's easy to figure out that raising an issue line 5 is wrong because the return type of the method is void, line 7 is wrong because Object is not the same as int, and line 11 is also wrong because of the variable arity of the method. From there, under the language section, select "Java", and then "MyCompany Custom Repository" under the repository section. You can raise an issue on a given line, but you can also raise it at a specific Token. Examples : CURSORs should not be declared inside a loop, EXAMINE statement should not be used, IF should be closed with END-IF, ... MAJOR Likelihood: What is the probability a hacker will be able to exploit it? If you have a fresh install or do not possess the same version, install the adequate version of the Java Plugin. It helped us to standardize our coding standards and write clean code, making sure no code with code smells goes to production. Before playing our rule against any real projects, we have to finalize its creation within the custom plugin, by registering it. Because we chose a TDD approach, the first thing to do is to write examples of the code our rule will target. (out/err)" // Noncompliant, Parameters in an overriding virtual function should either use the same default arguments as the function they override, or not specify any default arguments // Noncompliant; waaaay too long, Files should not have too many lines of code, "System. Do not give examples that make references to real companies or organizations: When a reference is made to a standards specification, e.g. These methods are used to register our rules with alongside the rule of the Java plugin. They will be translated in the final output. The RIPS SonarQube plugin lets you run scans from SonarQube and imports issues from the corresponding RIPS scans to SonarQube. Otherwise, use an h2 for it. It relates to the minimum version of SonarQube your plugin will support, and is generally aligned to your company's SonarQube instance. Hotspot - An optional protection is missing and the developer needs to do a review before deciding whether to apply a fix. Rule descriptions should contain the following sections in the listed order: Noncompliant Code Example - providing some examples of issues. If you refactor your code, rename, or move the class extending org.sonar.api.SonarPlugin, you will have to change this configuration. Check this example : https://github.com/SonarSource/sonar-custom-rules-examples/blob/master/java-custom-rules/src/main/java/org/sonar/samples/java/checks/SecurityAnnotationMandatoryRule.java. Go to Administration > Marketplace > Search for "Java I18n" > Install > Restart the SonarQube server. Examples: Avoid cycles between packages, ... an issue for a misnamed method should be raised on the line with the method name, and the method name itself should be highlighted. Go to Quality Profiles in SonarQube. Sometimes the line between Bug and Code Smell is fuzzy. You are using SonarQube and its Java Analyzer to analyze your projects, but there aren't rules that allow you to target some of your company's specific needs? Make sure creating this cookie without the "secure" flag is safe. In such a situation, it could be useful to take a look at another visitor provided with the API: org.sonar.plugins.java.api.tree.BaseTreeVisitor. Today, we are going to learn how to setup SonarQube on our machine to run SonarQube scanner on How to deactivate a rule in SonarQube Ruleset in Sonarqube 7.7 version. The hotspot-review should be done by developers by themselves without external help: Recommended Secure Coding Practices - describing all the ways to mitigate the risk. method complexity should be raised on the method signature, method count in a class should be raised on the class declaration. An Android project can be analysed with the standard SonarQube Java plugin and this plugin just allows to import Android Lint reports if needed. Put a dependency on the API of the language plugin for which you are writing coding rules. You need to download the sslr-{language}-toolkit-{version}.jar file corresponding to the version of your language plugin you have on your SonarQube instance. SonarQube takes project code as the input, analyzes it using pre-defined coding rules and publishes web based results giving overview of technical quality of code. Of course, before going any further, we need a key element in rule writhing, a specification! Powered by a free Atlassian Confluence Open Source Project License granted to SonarQube. Don't take over the interface with a narrative. Rules 540+. 500+ rules (including 100+ bug detection rules and 300+ code smells) Metrics (complexity, number of lines etc.) In the code snippet below, note the plugin API version () provided through the properties. (If you forget, the overnight automation will remember for you. Keeping this in consideration, how do you change rules in SonarQube? The test should fail with error message "At least one issue expected", as shown in the code snippet below. In answering, you should factor in Murphy's Law without predicting Armageddon. An Android project can be analysed with the standard SonarQube Java plugin and this plugin just allows to import Android Lint reports if needed. To do so, we will use a Test Driven Development (TDD) approach, relying on writing some test cases first, followed by the implementation a solution. don't write a novel. Once the nodes to visit are specified, we have to implement how the rule will react when encountering method declarations. In our code ‘testService.java’, we have used a sample system.out .print ln( ) method. It is not recommended to highlight a widely-used technology (weak in some contexts) when its replacement can only be done with such significant changes (eg: a new authentication system or a different database engine) that it would block developers who may not be responsible for the architecture of the application. During the specification of a rule, the following guidelines might also help: When assessing the default severity of a rule, the first thing to do is ask yourself "what's the worst thing that could happen?" changing severity of certain rules for project. You'll see (at least for Java projects ) links for all rules engines and one that includes all of them. com.ashish.custom.sonar.java.plugin.RulesList This class lists all custom rules and provides the list to the CustomJavaFileCheckRegistrar class to register them with sonarqube 6 com.ashish.custom.sonar.java.rules It helps in improving code quality by providing various metrics for bugs, vulnerabilities, security, code coverage, etc. As a first step, we can consequently safely cast the tree directly into a MethodTree, as shown below. The message for a secondary location is meant to be a hint to push the user in the right direction. For the sake of the exercise, lets consider the following quote from a famous Guru as being the specification of our custom rule, as it is of course absolutely correct and incontrovertible. Results summarize the status on project level which can be informative to management and is also possible to go on the issue level to see specific line of code causing the rule violation. It is also possible to use external files to describe rule metadata, such as a description in html format. Prior to running any rule, the SonarQube Java Analyzer parses a given Java code file and produces an equivalent data structure: the Syntax Tree. The complete list of rules, If SonarQube's results aren't relevant, no one will want to use it. what is the time to fix the issue? ), update the appropriate field on the References tab with the cited id. Hence, at the time being, you will need to install it manually: Obtain the RIPS plugin file (see table above). java, enterprise-integration, architecture, sonarqube,.net, php, static code analysis, code analyzer Published at DZone with permission of Ajitesh Kumar , DZone MVB . For instance, when browsing Java rules, you can see that there are 397 active guidelines that will be used when analysing your code: Once you get to know them, you can adjust the profile according to your needs. Login as an Quality Profile Administrator, Select the Language for which you want to create the XPath rule, Tick the Template criterion and select "Show Templates Only", Click on it to select it, then use the interface controls to create a new instance. Adding coding rules using Java. The below method main() is kept empty in ‘my testservice.java class’, as can be observed, SonarQube is recommending to comment on this method since this method is empty. This time, we will need to use the semantic API! The rules must be written in XPath (version 1.0) to navigate the language's Abstract Syntax Tree (AST). To do so, get back to our test class MyFirstCustomCheckTest, and update the test() method as shown in the following code snippet (you may have to import class org.sonar.java.checks.verifier.JavaCheckVerifier): As you probably noticed, this test class contains a single test, the purpose of which is to verify the behavior of the rule we are going to implement. For this chapter, you will need a local instance of SonarQube. Prior to running any rule, the SonarQube Java Analyzer parses a given Java code file and produces an equivalent data structure: the, Each construction of the Java language can be represented with a specific kind of Syntax Tree, detailing each of its particularities. We're an open company, and our rules database is open as well! It will cover all the main concepts of static analysis required to understand and develop effective rules, relying on the API provided by the SonarQube Java Plugin. Test passed? Grab the template project from there and import it to your IDE: Of course, before going any further, we need a key element in rule writhing, a specification! Re: How to create custom rules for Java in SonarQube? Since the rule should only raise an issue when these two types are the same, we then simply test if the return type is the same as the type of the first parameter using method is(String fullyQualifiedName), provided through the Type class, before raising the issue. In SonarQube, rules are divided into three self-explaining categories: bugs, vulnerabilities and code smells. At this point, we've completed the implementation of a first custom rule and registered it into the custom plugin. The rules you are going to develop will be delivered using a dedicated, custom plugin, relying on the. Understanding the logic of a piece of code is required before doing a little and easy refactoring (1 or 2 lines of code), but understanding the big picture is not required. add any related tags such as security, bug, etc. It should be in the imperative mood ("Do x"), and therefore start with a verb. Your rule should now be visible (with all the other sample rules). Create as many custom rules as required. Place this jar file in the SONARQUBE_HOME/extensions/plugins directory. This new version provides a default sqale mapping for the Android Lint rules and the ability to automatically execute lint has been dropped. Impact: Could the Code Smell lead a maintainer to introduce a bug? If you're writing rules for XML, skip down to the Adding your rule to the server section once you've got your rules written. If so, how to do it. It is acceptable to omit this section when there are too many equally viable solutions. You need to have your own profile by copying from built-in profile and then you can activate/deactive/customize rules at will. If you don't have a SonarQube platform installed on your machine, now is time to download its latest version from HERE! Why Noncompliant? No need to understand the logic but potential impacts. add the relevant standard-related tag/label such as cwe, misra, etc. I am trying to find a way to get a list of all Sonarqube Java (or whatever) rules (with keys, description, etc.) ls sonarqube_extensions/plugins/ sonar-java-plugin-5.14.0.18788.jar 以降はこの sonarqube_extensions/plugins ディレクトリにプラグインのjarファイルが残っている限りは個別のインストールは不要になります。 Rationale (unlabeled) - explaining why this rule makes sense. The see section is used to support the current rule, and one rule cannot be used as justification for another rule. 3400+ Static Analysis Rules Exceptions This class, on top of providing a bunch of useful methods to raise issues, also defines the strategy which will be used when analyzing a file. For example an issue for: When an issue could be made clearer by highlighting multiple code segments, such as a method complexity issue, additional issue locations may be highlighted, and additional messages may optionally be logged for those locations. // Compliant, This "switch" statement is useless and should be refactored or removed. You have to add a @RuleProperty to your Rule. Understanding the logic of a piece of code is required and it's up to the developer to define the remediation action. An issue message should always end with a period ('.') Select the Language for which you want to create the XPath rule. … Rule Set Information Ideally, the examples should depend upon the default values of any parameters the rule has, and these default values should be mentioned before the code block. In Sonar server, a rule is defined that mentions use logger instead of system.out. For the moment, don't touch these two properties. For example, with the hotspot, Impact: Could the exploitation of the vulnerability result in significant damage to your assets or your users? In the previous steps, we modified the implementation of the method to return an empty list, therefore not subscribing to any node of the syntax tree. Since all locations are likely to be on the same line, additional messages would only confuse the issue. Information about the analysis of Java features is available here. since it is an actual sentence, unless it ends with a regular expression, in which case the regular expression should be preceded by a colon and should end the message. Bug (Reliability domain) 3. For instance, when a rule uses parameters, or if its behavior relies on the detected version of java, multiple test files could be required. In this template, we rely on the version 6.0 (LTS version is 5.6, but compatibility is guaranteed when packaging the plugin). For example: the rule "Parameters should be final" will raise an issue on the method name, and highlight each non-final parameter. The Overflow Blog How to put machine learning models into production. Save these files somewhere in your storage. More rules for Java and PHP developers SonarQube’s analyzers are continuously being improved, and this new version brings solid improvements for Java and PHP. Creative Commons Attribution-NonCommercial 3.0 United States License. If there is shared interest, then it might be implemented for you directly in the related language plugin. This plugin is a Java project analyzer, the way to use it is the same as SonarJava. To do so, simply execute the test from the test file using JUnit. // Noncompliant, Every "switch" statement shall have at least one case-clause. Go back to the, method. It's also the property  which guarantees the compatibility with LTS 5.6. When possible, each issue should be raised on the line of code that needs correction, with highlighting limited to the portion of the line to be corrected. avoid using an additional message if the secondary location is likely to be on the same issue as the issue itself.
