Does this have any impact on speed of my build? Is there any tip to boostup my maven build with allocating more memory to it? Hopefully this can save someone else some time! Marquee Marquee 1, 20 20 silver badges 20 20 bronze badges.

My maven-compiler did not have a setting for a forked JVM, so I did not need to change anything there. Usually I try to avoid process forking as long as I don't get it running. So you have 3GB rest. As you can see your Xmx setting most probably could never be used be the JVM since the memory is simple not free.

Instead, you should be looking at the unit test that has caused the OOME, and trying to figure out if it is the fault of the unit test or the code that it is testing.
Start by looking at the stack trace. If there isn't one, run mvn In order to resolve java. It has equivalent effect with adding the JVM option to the Surefire plugin's configuration in pom.
