Consequently, as we will rely on version 4.5.0.8398 of the Java plugin, the SonarQube instance which will use the custom plugin will need version 4.5.0.8398 of the Java Plugin as well. The JavaCheckVerifier reported that lines 5, 7 and 11 are raising unexpected issues, as visible in the stack-trace above. SonarQube provides a quick and easy way to add new coding rules directly via the web interface for certain languages using XPath 1.0 expressions. Sonarqube is an automatic code review tool to detect bugs, vulnerabilities and code smells in your code. 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! 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. Then your logical choice may be to implement your own set of custom Java rules. To save rules click on the "Permalinks" tab when viewing an existing profile. … Application Security. How to write a rule In my view (that may differs from the SonarSourcE/SonarQube developer view), SonarQube is provding two kind of rules : Since all locations are likely to be on the same line, additional messages would only confuse the issue. Let's start with a core question – why analyze source code in the first place? To do so, it relies on usage of the JavaCheckVerifier class, provided by the Java Plugin rule testing API. Rationale (unlabeled) - explaining why this rule makes sense. Accepted formats are: "1.X" (for instance 1.6 for java 6, 1.7 for java 7, 1.8 for java 8, etc.) Once you have your answer, it's time to assess whether the Impact and Likelihood of the Worst Thing are High or Low. In this file, we consider numerous cases that our rule may encounter during an analysis, and flag the lines which will require our implementation to raise issues. They will be translated in the final output. Select the rule and activate it in the default quality profile. 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 The difficulty of exploiting a weakness should not be a criterion for specifying a hotspot or a vulnerability. In this article, we're going to be looking at static source code analysis with SonarQube– which is an open-source platform for ensuring code quality. E.G. If there is shared interest, then it might be implemented for you directly in the related language plugin. SonarQube 6.0 SonarLint for Eclipse 2.2.0 (includes Sonarlint core 2.4.0) Eclipse Neon 4.6.0 The most famous tools are Findbugs, PMD, Checkstyle; but also code coverage tools such as JaCoCo. Keeping code clean, simple, and easy to read is also a lot easier with SonarQube. In the code snippet below, note the plugin API version () provided through the properties. It inherits 236 active rules from default java profile “Sonar Way” Based on project need, changes can be made in the child profile. In SonarQube, rules are divided into three self-explaining categories: bugs, vulnerabilities and code smells. In this case, we chose to report the issue at a precise location, which will be the name of the method. Once the nodes to visit are specified, we have to implement how the rule will react when encountering method declarations. The rules you are going to develop will be delivered using a dedicated, custom plugin, relying on the SonarQube Java Plugin API. No need to understand the logic but potential impacts. This new version provides a default sqale mapping for the Android Lint rules and the // Noncompliant, Rename this variable to comply with the regular expression: [a-z]+ // Compliant, The title should start with a verb in the present participle form (-ing), The title should end with "is security-sensitive", Avoid creation of cookies without the "secure" flag, Creating cookies without the "secure" flag is security-sensitive. It is open-source, and available in SonarLint, SonarCloud and SonarQube. Your rule should now be visible (with all the other sample rules). For Vulnerabilities, the target is to have more than 80% of issues be true-positives. The method reportIssue(Tree tree, String message) from IssuableSubscriptionVisitor allows to report an issue on a given tree with a specific message. Integrating SonarQube as a pull request approver on AWS CodeCommit. An issue message should always end with a period ('.') The flag to be used is a simple ", " trailing comment on the line of code where an issue should be raised. If a "See" heading exists in the rule, then the "See also" title should be at the h3 level. Put a dependency on the API of the language plugin for which you are writing coding rules. Issue messages should contain the remediation message for bug and quality rules. 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. Put a dependency on the API of the language plugin for which you are writing coding rules. If not, then check if you somehow missed a step. In package org.sonar.samples.java.checks of /src/main/java, create a new class called MyFirstCustomCheck extending class org.sonar.plugins.java.api.IssuableSubscriptionVisitor provided by the Java Plugin API. In the pom.xml, define in the Maven Dependency Plugin all the JARs you need to run your Unit Tests. These methods are used to register our rules with alongside the rule of the Java plugin. 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. You can raise an issue on a given line, but you can also raise it at a specific Token. For instance, the kind associated to the declaration of a method will be org.sonar.plugins.java.api.tree.Tree.Kind.METHOD, and its interface defined by  org.sonar.plugins.java.api.tree.MethodTree. We're an open company, and our rules database is open as well! In general, these guidelines should be followed for secondary issue locations: All other things being equal, the positive form is preferred. Test passed? Because the flagged lines do not comply with the rule. MEDIUM Most of the time you can paraphrase the title: Importing Issues from Third-Party Roslyn Analyzers (C#, VB.NET). Exceptions For example: When correcting an issue requires action across multiple lines, the issue should be raised on the lowest block that encloses all relevant lines. For the sake of the exercise, lets consider the following quote from a famous. Java Internationalization (I18n) Rules for SonarQube Installation. 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.”. For XML, which is already immediately accessible to XPath, you can simply write your rules and check them using any of the freely available tools for examining XPath on XML. Once you've created your rule, you'll need to add it to a Quality Profile and run analysis to see it in action. Is it possible to create the rule for Java using the template that is available in SonarQube 6.0? Bug (Reliability domain) 3. Each construction of the Java language can be represented with a specific kind of Syntax Tree, detailing each of its particularities. Hi Julien My custom rule violation is not show in Eclipse. You'll see (at least for Java projects ) links for all rules engines and one that includes all of them. E.G. "Classes should not have too many lines of code", There is no need to mark anything "Compliant" in the Compliant Solution; everything here is compliant by definition. 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. 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. The Overflow Blog How to put machine learning models into production. Once your new rule is written, you can add it SonarQube: These are the guidelines that SonarSource uses internally to specify new rules. It's also the property  which guarantees the compatibility with LTS 5.6. You implemented your first custom rule for the SonarQube Java Analyzer! TRIVIAL MISRA, the following steps must also be taken: If needed, references to other rules should be listed under a "See also" heading. A custom plugin is a Maven project, and before diving into code, it is important to notice a few relevant lines related to the configuration of your soon-to-be-released custom plugin. It is acceptable to omit this section when there are too many equally viable solutions. 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. Go to Administration > Marketplace > Search for "Java I18n" > Install > Restart the SonarQube server. The remediation action might lead to locally impact the design of the application. Other rules should be linked to only if they are related or contradictory (such as a pair of rules about where { should go). The remediation action might lead to an impact on the overall design of the application. Creative Commons Attribution-NonCommercial 3.0 United States License. avoid using an additional message if the secondary location is likely to be on the same issue as the issue itself. Since our rule targets method declarations, we only need to visit methods. The list of node types to cover is specified through the nodesToVisit() method. Using generic exceptions such as Error, RuntimeException, Throwable, and Exception prevents calling methods from handling true, system-generated exceptions differently than application-generated errors. At this point, we've completed the implementation of a first custom rule and registered it into the custom plugin. Otherwise, use an h2 for it. Make sure creating this cookie without the "secure" flag is safe. If you refactor your code, rename, or move the class extending org.sonar.api.SonarPlugin, you will have to change this configuration. Import of test coverage reports; Custom rules; Useful links In rules already implemented in the Java Plugin, you will be able to find multiple rule using both approaches: An IssuableSubscriptionVisitor as entry point, helped by simple BaseTreeVisitor(s) to identify pattern in other parts of code. what is the time to fix the issue? This time, we will need to use the semantic API! The latest version of the plugin can be downloaded from HERE. 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. Don't hesitate to explore the semantic package of the API in order to have an idea of what kind of information you will have access to during analysis! don't write a novel. In this class, you will notice methods GetJavaChecks() and GetJavaTestChecks(). It helped us to standardize our coding standards and write clean code, making sure no code with code smells goes to production. Any piece of code in the rule title should be double-quoted (and not single-quoted). It is activated for project “Sample project for SonarQube”. This will automatically fail the build if … As its name is telling us, it is based on a subscription mechanism, allowing to specify on what kind of tree the rule should react. The second things to to is to activate the rule within the plugin. Now its finally time to jump in to the implementation of our first rule! SonarQube v8.3 extends XSS injection flaw detection to several common frameworks. To do so, override method visitNode(Tree tree), inherited from SubscriptionVisitor through IssuableSubscriptionVisitor. 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. Security Hotspot (Security domain) For Code Smells and Bugs, zero false-positives are expected. You have to add a @RuleProperty to your Rule. Before playing our rule against any real projects, we have to finalize its creation within the custom plugin, by registering it. In order to start working efficiently, we provide a empty template maven project, that you will fill in while following this tutorial. (If you forget, the overnight automation will remember for you. SonarQube is an open-source platform developed for continuous inspection of code quality. The property  is the minimum version of the Java Analyzer that will be required to run your custom plugin in your SonarQube instance. created earlier, copy-paste the following code: line 2: A constructor, to differentiate the case from a method; line 4: A method without parameter (foo1); line 6: A method returning the same type as its parameter (foo3), which will be noncompliant; line 7: A method with a single parameter, but a different return type (foo4); with a single parameter and same return type, but with non-primitive types (foo5), therefore non compliant too; line 10: A method with more than 1 parameter (foo6); line 11: A method with a variable arity argument (foo7); proceed to the next step of TDD: make the test fail! Because we chose a TDD approach, the first thing to do is to write examples of the code our rule will target. If so, how to do it. 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). Hotspot - An optional protection is missing and the developer needs to do a review before deciding whether to apply a fix. Why. In Sonar server, a rule is defined that mentions use logger instead of system.out. ... Thousands of automated Static Code Analysis rules, protecting your app on multiple fronts, and guiding your team. Before we start with the implementation of the rule itself, you need a little background. Languages not listed here don't support custom rules. 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. If you have a fresh install or do not possess the same version, install the adequate version of the Java Plugin. Everything worked well with SonarQube for all our … Generate the SonarQube plugin (jar file). The test should fail with error message "At least one issue expected", as shown in the code snippet below. Approval rules act as a gate on your source code changes. JDT itself provides very powerful quality checks, but there are not enabled by default. To do so, open class RulesList (org.sonar.samples.java.RulesList). This plugin is a Java project analyzer, the way to use it is the same as SonarJava. Description / Features. The RIPS SonarQube plugin lets you run scans from SonarQube and imports issues from the corresponding RIPS scans to SonarQube. Raising these issues is however correct accordingly to our implementation, as we didn't check for the types of the parameter and return type. Vulnerability - Something that's wrong which impacts the application's security and therefore needs a fix. 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. Tick the Template criterion and select 'Show Templates Only' Look for the XPath rule template. From there, under the language section, select "Java", and then "MyCompany Custom Repository" under the repository section. 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. To perform secure cryptography, operation modes and padding scheme are essentials and should be used correctly according to the encryption algorithm: Good to have but not required for rules that detect bugs. Don't take over the interface with a narrative. Now its finally time to jump in to the implementation of our first rule! Since our check is not yet implemented, no issue can be raised yet, so that's the expected behavior. To register the rule, simply add the rule class to the list builder, as in the following code snippet: Because your rules are relying on the SonarJava API, you also need to tell the SonarJava parent plugin that some new rules have to be retrieved. If it might benefit others, you can propose it on the Community Forum. 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. Features 500+ rules (including 100+ bug detection rules and 300 Why Noncompliant? JSP and Spring are covered for Java; Razor and ASP.NET Core MVC are added for C#. Generate the SonarQube plugin (jar file). I am trying to find a way to get a list of all Sonarqube Java (or whatever) rules (with keys, description, etc.) Recently we started using SonarQube for code quality, security checks and code coverage reports for our projects. (Yes = High). To do that, ask yourself these specific questions: Once you have your Impact and Likelihood assessments, the rest is easy: Rules can have 0-n tags, although most rules should have at least one. Code Smell - Something that will confuse a maintainer or cause her to stumble in her reading of the code. The rules you are going to develop will be delivered using a dedicated, custom plugin, relying on the. Features. Today, we are going to learn how to setup SonarQube on our machine to run SonarQube scanner on For example, if the highlighted missing protection (such as secure cookie flag) helps protect a bit against MITM attacks, list all mandatory protections that, at the contrary, greatly lower this risk (such as encryption). There are two profiles available in the Java section. For the implementation of this rule, we chose to use an IssuableSubscriptionVisitor as the implementation basis of our rule. RIPS Plugin Setup The RIPS plugin for SonarQube is currently not in the SonarQube plugin repository. Java. Select the Language for which you want to create the XPath rule. // Compliant, This "switch" statement is useless and should be refactored or removed. For a method, for instance, the semantic API will provide useful data such as a method's owner, its usages, the types of its parameters and its return type, the exception it may throw, etc. Go back to the, method. See : https://github.com/SonarSource/sonar-custom-rules-examples/blob/master/java-custom-rules/pom.xml#L147. The complete list of rules, Information about the analysis of Java features is available here. If SonarQube's results aren't relevant, no one will want to use it.
