Jenkins: java.lang.OutOfMemoryError: Java heap space

This error can be solved by manually adding a parameter to dedicate memory to the build process.

• In your Jenkins project, click configure.

• Scroll down to the Build section of the page to the Build Step titled Invoke Ant with the fields:

  • Ant Version: CodeScan Bundled Ant

  • Targets: sonar

• Click on Advanced.

• In the Java Options field, add the parameter -Xmx2000m. This will assign 2000mb of memory to you build.

If after increasing the heap space you get the error:

Error occurred during initialization of VM Could not reserve enough space for xxxxxxKB object heap

The problem may be that you are using a 32 bit version of Java. Please refer to the following article for more details.
