Benjamin Bentmann closed MNG-4514.
----------------------------------
Resolution: Not A Bug
Assignee: Benjamin Bentmann
This is a bug in the plexus-resources component (cf.
[r8418|http://fisheye.codehaus.org/changelog/plexus/plexus-components/trunk/plexus-resources?cs=8418]),
not Maven. Calling {{ClassLoader.getResource()}} when the resource name has a
leading slash only works in Maven 2.x due to buggy/non-standard classloaders of
ClassWorlds. Try this with a regular URLClassLoader and see it fail.
> Loading resource from plugin dependency using Plexus ResourceManager fails
> with leading slash

> When a maven plugin tries to load a resource(file) from a plugin dependency
> defined in a project pom file and the path to that resource begins with
> 'slash' / then the resource is not found. The code uses the Plexus
> ResourceManagers
> Example code that works in 2.2.1 and earlier and fails in Maven 3.0-alpha-5.
> If resource is in root of jar and configFile begins with forward slash then
> we get ResourceNotFoundException.
