Ian Brandt created MPIR-275:
-------------------------------
Summary: NPE in DependenciesReport
Key: MPIR-275
URL: https://jira.codehaus.org/browse/MPIR-275
Project: Maven 2.x Project Info Reports Plugin
Issue Type: Bug
Components: dependencies
Affects Versions: 2.6
Environment: Maven 3.0.4
Reporter: Ian Brandt
I suddenly started getting the same error as in MPIR-248, but with
maven-project-info-reports-plugin 2.6 and maven-dependency-plugin 2.5.1. I
updated to maven-dependency-plugin 2.7, but no change.
The error occurs on my CI server, but not on my local machine. Both reference
the same Archiva proxy repository, but have separate local repositories.
The failure started on a manually triggered build. There were no code changes
from the build triggered by the last commit, and that build succeeded. There
were no POM or dependency changes going back at least another 5 commits, and
all those builds succeeded as well. There have been 6 subsequent builds, a mix
of manually triggered and commit triggered ones, and they have all failed. I
enabled debug logging, but nothing is jumping out at me as abnormal.
Are there any further troubleshooting steps I should perform? I could provide
the debug log, but I'd have to scrub it a bit first.
