Description

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.

 /**
     * ResourceManager for getting a resource from a dependency jar
     *
     * @component
     * @required
     * @readonly
     */
    private ResourceManager locator;
...
protected void loadResource(String configFile) throws
            ResourceNotFoundException
    {
        InputStream inStream = null;
        if (configFile != null)
        {
            try
            {
                inStream =
                        locator.getResourceAsInputStream(configFile);
            } finally
            {
                if (inStream != null)
                {
                    try
                    {
                        inStream.close();
                    } catch (IOException ex)
                    {
                        throw new RuntimeException(
                                "Should not have happended", ex);
                    }
                }
            }
        }
    }

Will attach IT test.
