Description

When we run maven-invoker-plugin it takes on any MAVEN_OPTS or .mvn/jvm.config settings and runs with those. We specify 3.5GB of heap for the Maven process in .mvn/jvm.config so for each invocation maven-invoker-plugin will start a JVM with additional 3.5GB of heap.

There is no way of overriding the entire JVM configuration, but luckily the last -Xmx setting on the JVM command line is taken into consideration, so when configuring the maven-invoker-plugin we can set the <mavenOpts> configuration and it will be appended to the java command line arguments and the last -Xmx parameter will set the heap size.
