Subject [jira] Commented: (MNG-1898) Plugin classpath broken from 2.0 to 2.0.1
Date Fri, 06 Jan 2006 23:42:01 GMT
    [ http://jira.codehaus.org/browse/MNG-1898?page=comments#action_55129 ] 

Brett Porter commented on MNG-1898:
-----------------------------------

basically we need to: 
- restore compatibility with 2.0 version
- retain the fix above
- see if we can improve the classloading situation for things like MCHECKSTYLE-10 so people
don't need to create their own classloaders

the original bugfix for 2.0.1 was MNG-1804

> I'm working on a kodo plugin in the codehaus mojo sandbox. Using 2.0, it works fine.
In 2.1, it can't find xercesImpl, which is a transitive dependency of the plugin. Did something
change to cause new behavior (aka a bug) related to this? Just eyeballing the info below,
in 2.0, the instance of classloader was  org.codehaus.classworlds.RealmClassLoader but in
2.0.1 it is org.codehaus.plexus.util.RealmDelegatingClassLoader

> I tried specifying xercesImpl as a direct dependency and that didn't work either so I'm
not sure it's related to the transitivity.
