Sonar analysis for an Ant based Java project


In my previous post, i had explained the steps for installation and configuration of Sonar to analyse a maven based project in eclipse. In an another post, i had explained the usage of sonar-runner for non-maven based project.

In this post, I’m explaining the steps for sonar analysis of an ant based java project. Even if your java project is not Ant based, it is very simple to do the conversion in eclipse.

You just need to import your java project in eclipse and then right-click on your java project and click on export and select “Ant Buildfiles”. With this eclipse will automatically generate “build.xml” file for your java project. As a last step you have to let Eclipse know that it should use “Ant Builder” instead of the default java builder. For this right click on your java project, select “Builders” and click on “New” and select “Ant Builders”. Uncheck all other selected Builders in this window and click OK.


  1. Start Sonar server

bin\windows-x86-32\StartSonar.bat  (for 32 bit Windows)

2. Check if Sonar server is running by opening Sonar admin page “http://localhost:9000“. Default credentials – admin/admin.

3. Below is how my Java Project structure looks in eclipse:

4. Download sonar Ant task jar from here. Place this jar in “${ECLIPSE_HOME}\plugins\org.apache.ant_<some_version>\lib” directory.

5. Edit your java project’s Build.xml file to include sonar task as target. You can refer my Build.xml and make changes as per your need:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <!-- WARNING: Eclipse auto-generated file.
 Any modifications will be overwritten.
 To include a user specific buildfile here, simply create one in the same
 directory with the processing instruction <?eclipse.ant.import?>
 as the first entry and export the buildfile again. -->

 <property name="sonar.jacoco.antTargets" value="run-tests" />

<sonar:sonar key="com.sanjit.test.CalculatorAntJavaProject" version="0.1-SNAPSHOT" xmlns:sonar="antlib:org.sonar.ant" />

6. Add “sonar” to Ant command line argument.  Right click on java project -> Select Builders -> Select Ant Builder -> Edit -> Select Main tab -> Add “sonar” to “Arguments” -> Apply -> OK.

7. Build your java project – Select java project -> Click on “Project” from the eclipse main tab -> Click “Build Project”. This will compile your java project, run your unit test cases and do a sonar analysis.

8. Login to your java project dashboard in sonar. This should be now showing all the violations, code coverage and unit test case details for your java project.

    • I wrote it 3 yrs back. Unfortunately, I don’t have the code base with me now. It was a simple ant based java project, nothing special. You could try setting up, by following the steps in the post, with your own project and if you face any issues, do comment here and I’ll try to help you out.


  1. Hi Sajith
