Adding resources section to POM without directory element causes
NullPointerException
-------------------------------------------------------------------------------------
Key: MNG-1147
URL: http://jira.codehaus.org/browse/MNG-1147
Project: Maven 2
Type: Bug
Components: maven-resources-plugin
Versions: 2.0-beta-3
Reporter: David Jackman
Priority: Minor
Add a resources section to a POM without a directory element (in my case I did
have a filtering element, but that doesn't seem to matter). Do a build (at
least to the resources:resources goal). A NullPointerException is thrown:
java.lang.NullPointerException

Obviously, this is an error situation, but instead of throwing a runtime
exception, the resources plugin should report an error that a directory was not
provided.
