Using maven release plugin on multi-module project - maven

Question

I have a multi-module project with two modules: war and ear module. I'm trying to use Maven release plugin to manage releases.
My config so far...

I have two profiles - dev (which is active by default) and release (which is activated by release plugin). First, I had some problems with ant run (file paths) when releasing version, so I've used two profiles with some properties defined, that are used in ant run. Ant script is now executed properly, but I have another problem: plugin attempts to upload some release files twice which causes error:
executing mvn release:prepare "-Darguments=-Dmaven.test.skip=true": log
executing mvn release:perform "-Darguments=-Dmaven.test.skip=true": log
As you can see form logs, Test-WAR-0.0.1-sources.jar is uploading twice. Why is that? How can I edit my configuration to upload it only once?

Answer 1

It is quite possible that you suffer from the same bug as I did some years ago:
Maven deploy-file goal: Why does the first execution interfere with the second one?
Try to update the Maven deploy plugin to version 3.0.0-M1.
