Description

DependenciesReport.java, inside getMavenProjectFromRepository( Artifact artifact, ArtifactRepository localRepository )

projectArtifact.file is always null, and when calling mavenProjectBuilder.buildFromRepository causes

java.lang.NullPointerException
at org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolve(DefaultArtifactResolver.java:82)
at org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolve(DefaultArtifactResolver.java:63)

at org.apache.maven.reporting.AbstractMavenReportRenderer.render(AbstractMavenReportRenderer.java:65)

I've made a quick fix ignoring system dependencies, not sure if we want to change it
Inside renderBody
if ( Artifact.SCOPE_SYSTEM.equals( artifact.getScope() ) )

{ continue; }
