Bug 1014789

Steps to reproduce :

(Ensuring eclipse-m2e-core is installed)

1) hg clone http://icedtea.classpath.org/hg/thermostat
2) Start Eclipse on a separate workspace (thermostat is a fairly large project)
3) File -> Import -> Existing Maven Projects and point to the location of the thermostat project (top-level)
4) You may need to update all the maven projects, but once this is done, the following errors should be in the Problems View :

Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.6:resources failed. (org.apache.maven.plugins:maven-resources-plugin:2.6:resources:default-resources:process-resources)   pom.xml /thermostat-vm-heap-analysis-client-core        line 47 Maven Build Problem

or

Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.5:resources failed. (org.apache.maven.plugins:maven-resources-plugin:2.5:resources:default-resources:process-resources)   pom.xml /thermostat-assembly    line 39 Maven Build Problem

There's about 62 of these errors for me but they're pretty much identical.

I believe I've identified the cause as being an NPE in org.codehaus.plexus.util.AbstractScanner#isIncluded called from org.eclipse.m2e.core.internal.builder.ResourceScanner @ line 67 :   if(isIncluded(relpath) && !isExcluded(relpath)) {

In plexus-utils < 3.0.5 (ie. F18) this would not be an issue, but as of 3.0.5 ( F19 + ) plexus-utils introduced a new API method "setupMatchPatterns()" and changed the implementation of "isIncluded/isExcluded/etc." to require that method to have been executed.

I've attached a patch that seems to fix things for me (scratch build at http://koji.fedoraproject.org/koji/taskinfo?taskID=6016916)

An additional specfile change was needed to get dependencies resolving properly.
