Question

I get following exception when building using Jenkins. This exception raises after running Cucumber tests.

Can anyone tell the exact spot that fails on the java heap space?

Do you have any idea what can be done in order to solve it?

Some background: I had a java heap space during the Cucumber tests, after I increased the memory, Cucumber tests pass, but I get this java heap space right after.

Thanks,

Lior

Go into the Jenkins settings and add the environment variable MAVEN_OPTS to -Xmx512m -XX:MaxPermSize=256m. It looks like after your tests are finished it’s trying to parse the results but the XML file is too large.
