NPE when calling dependency:analyze

Hi,

When using Maven 4.0.0-alpha4 and invoking dependency:analyze goal the NullPointerException is happening. I've created a simple reproducer: https://github.com/c00ler/maven-dependency-analyze-npe

The exception is happening here. I assume, since analyze is a standalone goal, the lifecyclePhase is null in the event (see the attached screenshot). This is a recent change: https://github.com/apache/maven/commit/c1a900190f6e0fccf23889cb32f701459babfb7f, only 4.0.0-alpha4 is affected.
