             Summary: NPE in MultiThreadedBuilder
                 Key: MNG-6315
                 URL: https://issues.apache.org/jira/browse/MNG-6315
             Project: Maven
          Issue Type: Bug
          Components: core
            Reporter: David Hoover


This smells similar to MNG-6170

To reproduce, clone https://github.com/prestodb/presto (I've tested, in particular, at c0186a71815be31bac80253827e62c16fd04069f) and try to 'mvn -X -e versions:set versions:commit -DnewVersion=asdf'

That NPEs on https://github.com/apache/maven/blob/master/maven-core/src/main/java/org/apache/maven/lifecycle/internal/builder/multithreaded/MultiThreadedBuilder.java#L200 (projectBuild.getProject() has already been called up at https://github.com/apache/maven/blob/master/maven-core/src/main/java/org/apache/maven/lifecycle/internal/builder/multithreaded/MultiThreadedBuilder.java#L129 so presumably it's that lifecycleModuleBuilder is null?)

Running as two separate actions ("mvn versions:set" and then "mvn versions:commit") works for me, but not when combined.
