[jira] Commented: (MNG-1334) classpath related error when invoking the rmic task from maven

Kenney Westerhof commented on MNG-1334:
---------------------------------------

Here is a complete POM that works. To test it I put the SUN 'RMI tutorial' code 
in src/main/java,
and added a 'setLogger(org.apache.log4j.Logger)' to 'Hello.java' and 
'HelloImpl.java', to test
dependencies (it won't work in practise, but just illustrates the use of 
dependencies).

Generally: if your plugin needs dependencies to RUN (i.e. to execute 3rd party 
code), add those
dependencies to the PLUGIN dependencies - they have nothing to contribute to 
your projects code,
they're just used for building.
