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 Priority: Critical I have a report and a mojo that seeks transversal dependencies. It shows a nullpointer in the DefaultDependencyTreeBuilder. I can not figure it out what is wrong sice the implementation off DependencyTreeBuilder is assigned by Maven and I have no controll on the logger. Here is the code snippet //members /** * Used to look up Artifacts in the remote repository. * * @parameter expression= * "${component.org.apache.maven.artifact.factory.ArtifactFactory}" * @required * @readonly */ protected org.apache.maven.artifact.factory.ArtifactFactory artifactFactory; /** * Used to look up Artifacts in the remote repository. * * @parameter expression= * "${component.org.apache.maven.artifact.resolver.ArtifactResolver}" * @required * @readonly */ protected org.apache.maven.artifact.resolver.ArtifactResolver resolver; /** * Artifact collector, needed to resolve dependencies. * * @component role="org.apache.maven.artifact.resolver.ArtifactCollector" * @required * @readonly */ protected ArtifactCollector artifactCollector; /** * @component * role="org.apache.maven.artifact.metadata.ArtifactMetadataSource" * hint="maven" * @required * @readonly */ protected ArtifactMetadataSource artifactMetadataSource; /** * Dependency tree builder component. * * @component expression= * "org.apache.maven.shared.dependency.tree.DependencyTreeBuilder" * @required * @readonly */ private DependencyTreeBuilder dependencyTreeBuilder; //sample snippet to use in report and mojo ArtifactFilter artifactFilter = new ScopeArtifactFilter( Artifact.SCOPE_COMPILE); DependencyNode dn; getLog().info("Start"); try { dn = dependencyTreeBuilder.buildDependencyTree( project, localRepository, artifactFactory, artifactMetadataSource, artifactFilter, artifactCollector); } catch (DependencyTreeBuilderException e) { e.printStackTrace(); getLog().error("oeps",e); } getLog().info("Done"); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
