-------------------------------------
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.
