I have a Maven project with JPA classes that use the openjpa-maven-plugin to enhance the entities at compile via the enhance goal of the plugin.

From Jenkins, I use the Jenkins Maven project plugin to build my Maven projects.

When I instruct the plugin to use these Maven args:

clean install -DskipTests

The plugin fails:

Notice the immediate failure after the line:

openjpa-maven-plugin:2.2.2:enhance (enhancer)

There's no details about what the error is.

When I run a normal mvn clean install -DskipTests from Jenkins as a batch command, it builds as expected. This used to work at one point. My only guess is the plugin was broken at some point.
