NPE in org.apache.maven.artifact.DefaultArtifact.hashCode
---------------------------------------------------------
Key: MNG-590
URL: http://jira.codehaus.org/browse/MNG-590
Project: Maven 2
Type: Bug
Versions: 2.0-alpha-3
Reporter: Steve Loughran
Attachments: pom.xml
Getting an NPE when attempting to write a POM/. Now, an NPE in a hashCode
usually means a gulf between the classes expectatoins and what fields are
configured. I dont see anything obvious missing from my pom, though of course I
am just learning maven. Either the hashcode operator needs fixing to handle
missing data, or something upstream should fail with a meaningful error.
