why am i facing this error ? is the issue(bug) with Sonarqube plugin in Jenkins?
for time being to avoid this error i have deleted Sonar post build step and added the sonar analysis step in maven goals for maven 3.0.4
Maven goals :: clean install -Dmaven.test.skip=true -Dsonar.jdbc.url=jdbc:postgresql://sonardb.test.com:5555/sonar -Dsonar.host.url=http://localhost:9000/sonar org.codehaus.mojo:sonar-maven-plugin:2.6:sonar <br>
but this is a temporary solution, I would like to use Sonar post build step in my job configuration and not face this error.
Thanks for your help

Answer 1

SonarQube FAQ recommends the following:
If you get this error message after launching the maven command line "mvn sonar:sonar" add the "-U" parameter to the command line. Maven will then update its local repository with the latest version of the Sonar Maven plugin.
If adding the "-U" parameter doesn't fix your issue, you've certainly encountered Maven bug MNG-4001. The only known workaround is to delete the org\codehaus\mojo directory in your local Maven repository. Of course, if your local Maven repository is synchronized with a repository manager like Nexus, this operation must be also done on the repository manager side.

Answer 2

The problem is simply cause you are using the wrong coordinates of the plugin:
'org.apache.maven.plugins:maven-sonar-plugin'
The sonar-maven-plugin is not part of Apache Software Foundation.
You will find it here:
http://www.mojohaus.org/sonar-maven-plugin/
And how to use it here:
