If you have, you’ve probably tried what most of us tried, and you’ve attempted to increase Maven’s heap capacity using MVN_OPTS: That would normally work fine if the error we received is something like: Unfortunately, though, this doesn’t solve the problem because Maven actually uses a separate JVM for each JUnit test execution! So while we have successfully enabled Maven to be a hog, our tests are still running in a constrained environment. What we need to do instead is increase the memory capacity of the Maven Surefire launcher:
