Multi-module project fails "mvn verify" with ".polyglot.pom.yml isn't a file"

[makeamark1]

When running "mvn verify" in a multi-module project using "pom.yml" for all Maven POMs, one of the submodules consistently fail with the following error message:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-jar-plugin:2.6:jar (default-jar) on project foo: Error assembling JAR: /Users/vsipuli/foo/.polyglot.pom.yml isn't a file. -> [Help 1]

What can be done to fix or work around this issue?

Do you have an open project where it can be reproduced?
