             Summary: maven-invoker-plugin taking as much heapspace as the Maven itself
                 Key: CAMEL-13496
                 URL: https://issues.apache.org/jira/browse/CAMEL-13496
             Project: Camel
          Issue Type: Bug
          Components: build system
            Reporter: Zoran Regvart
            Assignee: Zoran Regvart
             Fix For: 3.0.0-M3


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.
