    Description

      When building a project for the first time, maven fails with an internal NPE (see stacktrace below). This happens in case the first build is a parallel build (-T 5C), regardless for the actual goal (install, deploy,..). When the build is first run without -T, subsequent builds run without any issues.

      Given the code in http://svn.apache.org/viewvc/maven/maven-3/tags/maven-3.0.4/maven-core/src/main/java/org/apache/maven/lifecycle/internal/MojoExecutor.java?revision=1232336&view=markup projectToResolve seems to be null, which seems to be a MavenSession problem (just guessing here).
