Live example If you want to see a live example of the capabilities of the Java Ecosystem, you can have a look at Sonar on Sonar.

Description / Features

The ecosystem enables analysis of Java projects within Sonar.

Installation

The Java Ecosystem is provided with Sonar.

As any other plugins, you can update it through the Update Center or download new version into the SONAR_HOME/extensions/plugins directory. Then restart the Sonar server.

Usage

Run a Sonar Analysis

To launch a Sonar analysis of your Java project, it is recommended to use:

• Maven for Maven projects
• Ant for Ant projects
• Sonar Runner otherwise

Sample projects for each analyzer are available on GitHub that can be browsed or downloaded: /projects/languages/java

Unit Tests and Code Coverage Reports

Android

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.
