Hi.
I'm struggling to make my plugin work.
It is a 1:1 copy of the http://maven-jaxb1-plugin.dev.java.net/ ported onto
jaxb2. I'm getting 'Unable to find the mojo' error and the stack trace shows
that I have a ClassNotFoundException.
I have hot no idea why.
The class is clearly in the jar and the jar is clearly in the realms...
Does anyone have any suggestions on how could I debug this stuff? What may be
possibly wrong?
I'd be grateful for any help. Just can't resolve this myself.
Bye.
/lexi
