Description / Features
The ecosystem enables analysis of Java Ecosystem is a set of plugins used to monitor the quality of Java projects within Sonar.
On top of the coding rules provided by the SonarQube engine, you can activate rules from Checkstyle, FindBugs, PMD, Clirr, and fb-contrib. However, we highly recommend that you limit your Quality Profiles to from the SonarQube engine because we believe they are faster, more accurate (fewer false positives and false negatives), and more usable (they have better descriptions, etc). Read this blog post for more details.
By default the Java Ecosystem is provided with Sonar.As any other plugins, you can update it through the SonarQube. You can update it from the Update Center or download new version into the SONAR_HOME/extensions/plugins directory. Then restart the Sonar serverthe latest release from this page header. Don't forget to check the upgrade notes.
- SonarQube Runner: recommended for all non-Maven projects
- Maven: recommended for all projects built with Maven
- SonarQube Ant Task: to integrate with projects built with Ant
- Gradle: to integrate with projects built with Gradle
- The source directory must be set to the directory containing the top parent package. For example, if your directory structure is src/

Extending Coding Rules using XPath
New coding rules can be added using XPath. See the related documentation.
To navigate the AST, download the SSLR Java Toolkit.
- main/java/com/mycompany/..., the source directory must be set to src/main/java.
- The source directory tree must match the package declaration. For example, the following class:
package com.mycompany.mypackage; ...
must be located in the following directory: [mySourceDirectory]/com/mycompany/mypackage/MyClass.java. Otherwise you would get an error like below while running your analysis:
Exception in thread "main" org.sonar.batch.bootstrapper.BootstrapException: org.sonar.squid.api.AnalysisException: Got an exception - org.sonar.squid.api.AnalysisException: The source directory does not correspond to the package declaration com.mycompany.mypackage, file : ..\src\MyClass.java ...
Tests and Code Coverage
The default code coverage engine for unit tests can be set in Settings > General Settings > Java > Code coverage plugin property.
To deal with unit tests and code coverage, see Code Coverage by Unit Tests for Java Project tutorial.
To deal with integration tests and code coverage, see Code Coverage by Integration Tests for Java Project tutorial.

All the valuable rules from PMD and Checkstyle were rewritten based on our own SSLR technology. These rules are now available in the SonarQube repository. Deprecated rules from PMD and Checkstyle are flagged as so and their replacement is stated in the rule description:
