I'm compiling an open source project with "mvn install" but ended up with java.lang.OutOfMemoryError: Java heap space. I tried to execute java -Xmx256m but the output was java synopsis which indicated it's an invalid command.

I'm using jdk1.5.0_08, any ideas why this is happening?

Thanks,

Set the environment variable:

MAVEN_OPTS="-Xmx512m"
