MTStorm commented on MSHARED-80: -------------------------------- Thanks, but the problem remains. Even when I copy the entire TreeMojo and deploy it in an other groupId, the nullpointer remains... Here is how the TreeMojo does it. /** * The dependency tree builder to use. * * @component * @required * @readonly */ private DependencyTreeBuilder dependencyTreeBuilder; > NullPointer in DefaultDependencyTreeBuilder.java:93, no logger > --------------------------------------------------------------- > > Key: MSHARED-80 > URL: http://jira.codehaus.org/browse/MSHARED-80 > Project: Maven Shared Components > Issue Type: Bug > Components: maven-dependency-tree > Affects Versions: maven-dependency-tree 1.2 > Environment: Windows XP 64 JDK 1.6 > Reporter: MTStorm > Assignee: Mark Hobson > Priority: Critical > > I have a report and a mojo that seeks transversal dependencies.
