Subject [jira] Created: (MSHARED-80) NullPointer in DefaultDependencyTreeBuilder.java:93, no logger
Date Tue, 04 Nov 2008 23:32:51 GMT
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");
