If I run mvn install -DskipTests=true in the project directory, it succeeds. If I run mvn install -DskipTests=true from the top-level project directory (tez-dist is a module), I get this error.

Apache Maven 3.6.0

David Mollitor commented

I can't quite figure it out, but the plugin is unhappy with one of the other modules. By commenting out a few of the other modules, it now succeeds.

David Mollitor commented

The problem module is:

https://github.com/apache/tez/blob/c2d48a688e041e2b5689d26908a7de7d135bff3e/docs/pom.xml#L20

Maybe because it has no dependencies defined?

Tamas Cservenak commented

Essentially the org.apache.maven.project.MavenProject#dependencyArtifacts is null, but it cannot be null when project has resolved dependencies (even w/o dep it would be empty set, not null). Please create a reproducer and explain how you invoke it, as it seems m-assembly-p in your case is invoked BEFORE project dependencies are resolved?
