maven-xdoclet-plugin creates faulty classpath using m2-eclipse/maven-embedder 
w/latest classworlds
--------------------------------------------------------------------------------------------------

                 Key: MOJO-797
                 URL: http://jira.codehaus.org/browse/MOJO-797
             Project: Mojo
          Issue Type: Bug
          Components: xdoclet
         Environment: Windows XP/maven embedder 2.1.0 
            Reporter: Cliff Resnick


The problem occurs when the OS is windows and the local_repo is under 
"Documents and Settings/user/.m2", very common setup in windows, or any 
situation where the repo is under a directory where the name contains space 
characters.

The classworlds supplied URL[] array elements are encoded, with"%20" for 
spaces, and the classpath is unusable with this encoding.
Preventing this is easy; in the XDocletMojo  just change:

                                classpath += (classpath.length() == 0 ?"" : 
java.io.File.pathSeparator ) + cpe[i].getFile();
to
                                classpath += (classpath.length() == 0 ?"" : 
java.io.File.pathSeparator ) + URLDecoder.decode(cpe[i].getFile(),"UTF-8");

I don't know why this crept in just now. I'm using the latest classworlds to 
patch an otherwise broken maven-embedder 2.1.0, in oder to use an M2 Eclipse 
plugin version that works with settings.xml. I got everything working great, 
but I did have to patch this plugin, though in fact the problem might be with 
classworlds. In any event, it's a good defensive measure.
