> Key: MNGECLIPSE-157
> URL: http://jira.codehaus.org/browse/MNGECLIPSE-157
> Project: Maven 2.x Extension for Eclipse
> Issue Type: Wish
> Components: Dependency Resolver
> Affects Versions: 0.0.9
> Reporter: Tuomas Kiviaho
> Assigned To: Eugene Kuleshov
> Attachments: child.pom, NullPointerException.jpg, parent.pom
>
>
> When inserting a dependency (in my case jaxen) which has a dependency of it's
> own (xercesImpl) to a project that has a parent which has the same dependency
> (xercesImpl) already declared (scope was system) a NullPointerException
> emerges to the WTP xml editors topmost row and classpath container doesn't
> show anymore any of the dependencies. Workspace log file and console did not
> show any anomalities.
> With standalone maven everything work just fine, but with embedder I managed
> to pull out a following stacktrace
> java.lang.NullPointerException
> at
> org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolve(DefaultArtifactResolver.java:82)
> at

> at org.maven.ide.eclipse.Maven2Executor.main(Maven2Executor.java:53)
> This seemed very familiar and here's a link
> <http://jira.codehaus.org/browse/MPIR-2> to another project. This issue has
> been around for quite a while and despite the status FIXED, I don't think
> this actually is fixed but at least it has been patched couple of times.
> Workaround: Add an exclusion clause to the new dependency if you have it's
> dependencies already declared in parent.
> What is left for this project could be a more informative way to express
> runtime exceptions/errors when embedder fails to do so. NullPointerException
> in the xml editor gives a wrong expression where the problem actually
> resides. I'd prefer m2 console over eclipse workspace log.
