How can I make the exec-maven-plugin goal be invoked with the Maven package phase?

Question

I've configured exec-mavein-plugin in my module's pom.xml file, but something isn't quite right.

I can invoke the goal directory mvn exec:exec and it works correctly and creates an executable file.

I believe it is configured correctly to be attached to the package phase. But when the package phase is invoked the output file is not created. I'm hoping a small tweak to the configuration will fix it.

Here is the pom.xml file.
