NullPointerException from BuildInfoRecorder in multi-module project

[odrotbohm]

I'm running the Artifactory Maven Plugin 2.4 like this: mvn deploy -Dartifactory.server=… -Dartifactory.staging-repository=… -Dartifactory.username=… -Dartifactory.password=… -Dartifactory.build-name=… -Dartifactory.build-number=… and get the following exception. Other projects just work fine.

@olivergierke, can you please provide a sample project that reproduces this exception so that we can debug it?

[odrotbohm]

You can try this to reproduce:

$ git clone https://github.com/spring-projects/spring-data-rest
$ cd spring-data-rest
$ mvn deploy -Prelease -DskipTests -Dartifactory.server=https://repo.spring.io -Dartifactory.staging-repository=test-libs-staging-local

It fails on the root project with above mentioned NullPointerException. I have other multi-module projects that work fine so it might be something special about this one's particular setup. The Artifactory Maven plugin configuration for the working projects is the same though.

If I remove the Enforcer plugin from the root POM, the build seems to work.
