NPE for Ant plugin example
I attempted to create the hello example outlined here:
http://maven.apache.org/guides/plugin/guide-ant-plugin-development.html
But, I'm getting the following. See attached pom.xml. Maven 2.0.2.
Known issue?

RE: NPE for Ant plugin example
Posted by Chris Wall <cw...@bea.com>.
My bad. My mojo meta-data file and Ant script were located in
src/scripts instead of src/main/scripts (default).
Although, the NPE (all NPEs) should be translated to a more meaningful
message.
Thanks.
