Peter De Maeyer commented on MOJO-1468:
---------------------------------------
Looking further into the issue, I am beginning to understand better what is
goign on. My earlier patch was a bit too short-sighted. Although it does fix
the immediate symptom, it does not fix the root cause. Since I explicitly
define the native class name in the configuration, it should not even have to
scan for native classes. It only does that in case the native class name is not
configured.
So... the question I should be asking is: why aren't any of the fields in
NativeJavahMojo filled in, even though I've configured the corresponding values
in the pom.xml? Does M2Eclipse somehow break the configuration of
NativeJavahMojo, forcing it to fall back to defaults?
I don't have the answers (yet), but I really need the native plugin to work so
I'll keep looking...
