Thiago Leão Moreira commented on MPIR-131:
------------------------------------------
This issue is easy reproduced with a project where all the dependencies has the
"system" scope.
> NPE in printArtifactsLocations() for blacklisted repo
> -----------------------------------------------------

> Key: MPIR-131
> URL: http://jira.codehaus.org/browse/MPIR-131
> Project: Maven 2.x Project Info Reports Plugin
> Issue Type: Bug

> Environment: Linux (Sun JDK 1.6), Windows (IBM VM 1.4). No direct
> Internet access; going through local Artifactory repository.
> Reporter: Klaus Brunner
> Priority: Critical

> I'm getting NPEs when running the reports plugin at this location:

> Taking a brief look with the debugger, it appears that the totalByRepo map in
> DependenciesRenderer.printArtifactsLocations() is empty - so looking up any
> entry will of course return null and result in an NPE here:
> totalRow[idnum++] = totalByRepo.get( repokey ).toString();
> Note that this used to work fine before the 2.1 release.
