How to pass systemProperties when invoking exec:java plugin in maven?

Question

I want to use the exec:java plugin to invoke the main class from command line. I can pass arguments from the command line using -Dexec.args=\"arg0 arg1 arg2\",

Answer 1

There is no way to set the parameter on the command line.

However, since exec:java is not forked, you can just pass a system property to maven and it will be picked up by exec:java as well.

mvn -Dkey=value exec:java -Dexec.mainClass=com.yourcompany.yourclass \
    -Dexec.args="arg1 arg2 arg3"
