Solve unrelated svn blames while building projects with maven

Previously I have used Subversion as the version control system. Then moved the projects to Git. Converted all the Jenkins build jobs accordingly. But while building some sonar jobs got below error.

[ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.6:sonar (default-cli) on project YourTestProject: The svn blame command [svn blame --xml --non-interactive -x -w --username ******** --password ******** src/your/test/project/code/path/Main.java] failed: svn: 'src/your/test/project/code/path/' is not a working copy -> [Help 1]

Since we are using Git and so no need of any svn blames. Using below parameters disabled svn activities.

-Dsonar.scm.disabled=True

Hope this will help you too.

Cheers...!!

Solve Jenkins Maven jobs build fail due to OutOfMemoryError

There are two major OutOfMemoryError types.

1. java.lang.OutOfMemoryError: Heap space
2. java.lang.OutOfMemoryError: PermGen space

You can easily solve this by adding/changing Jenkins environment variables.

Go to

Manage Jenkins >> Configure System >> 

In the Global Properties section check the Environment Variables check box.

Then add parameters as below

Name: MAVEN_OPTS

Value: -Xmx1024m -XX:MaxPermSize=1024m

Setting Xmx will solve your Heap Space issue and setting XX:MaxPermSize will solve your PermGen Space issues.

Cheers...!!
