Description Jan Lahoda 2012-04-06 07:50:27 UTC 
Created attachment 117924 [details]
The NPE as shown in the Show and Resolve Problems dialog.

While trying to reproduce #210725, I have:
1. cloned the hudson's git:
git clone git://git.eclipse.org/gitroot/hudson/org.eclipse.hudson.core.git
2. opened the root project, ran the priming build. It failed after a while (and after downloading tons of libraries) with something like:
---------------------------
cd /usr/local/home/lahvac/src/nb/org.eclipse.hudson.core; JAVA_HOME=/usr/lib/jvm/java-6-openjdk /usr/local/home/lahvac/src/nb/outgoing/nbbuild/netbeans/java/maven/bin/mvn install
Scanning for projects...
The POM for org.eclipse.hudson.tools:maven-hpi-plugin:jar:3.0.0-SNAPSHOT is missing, no dependency information available
The build could not read 1 project -> [Help 1]
  
  The project org.eclipse.hudson.plugins:hudson-plugin-parent:3.0.0-SNAPSHOT (/usr/local/home/lahvac/src/nb/org.eclipse.hudson.core/hudson-plugin-parent/pom.xml) has 1 error
    Unresolveable build extension: Plugin org.eclipse.hudson.tools:maven-hpi-plugin:3.0.0-SNAPSHOT or one of its dependencies could not be resolved: Could not find artifact org.eclipse.hudson.tools:maven-hpi-plugin:jar:3.0.0-SNAPSHOT -> [Help 2]

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

-------------
3. opened hudson-core module, tried to (prime) build it, etc. Failed, as well, so tried to build the parent pom again, with the above result again.
4. tried to open hudson-plugin-parent, so that I could manually prime-build it, but all I can see in its Show and Resolve Problems is the attached exception and request to report a bug.

Comment 2 Milos Kleint 2012-04-06 08:00:15 UTC 
the project is using an extensions plugin in -SNAPSHOT version that is apparently not available in local repository.

either checkout  and build the plugin (if current sources match the version) or hunt for the repository that contains that plugin's artifacts.. that would include searching the project's website and/or mailing lists..

have you tried later to build with maven on cmd line? what was the result there?

I will investigate the exception thrown, is most likely a bug in maven or our embedding
Comment 3 Jan Lahoda 2012-04-06 08:14:09 UTC 
I have figured that I would need to find the correct repository with the plugin - but without much luck so far. May not be really necessary for me to build it, anyway.

Comment 4 Jesse Glick 2012-04-09 20:54:26 UTC 
Stack trace indicates bug in NbWorkspaceReader, which is sometimes returning null from findVersions against contract.

As to the project in question, AFAIK Hudson is simply not buildable from the Eclipse repo yet, or at least not without special tricks; if you want sources which are not broken, stick with https://github.com/hudson/hudson.git for now.
