maven jetty plugin - how to control vm arguments?
In particular, I want to do something like this:
mvn -DjvmArgs="-Xmx2000m -Xms1000m -XX:PermSize=512m -XX:MaxPermSize=512m" jetty:run -Pmyprofile
Oh, and I would like to do this without having to modify the pom files or set any environment variables.. etc
I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html
In Unix:
Add the
MAVEN_OPTSenvironment variable to specify JVM properties, e.g.export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.
In Win, you need to set environment variable via the dialogue box
Add ... environment variable by opening up the system properties (
WinKey + Pause),... In the same dialog, add theMAVEN_OPTSenvironment variable in the user variables to specify JVM properties, e.g. the value-Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.
