Passing JVM parameters to Maven from the command line
Use the -D switch and clunk the JVM parameters onto that one,
like so:
$ mvn clean install -DXmx1024m -DXX:MaxPermSize=256m
Always pass the same JVM parameters to Maven
Define MAVEN_OPTS in your .bashrc:
export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m"
