[Maven] Xtend maven plugin seems to have a problem with symlinks #449048
[xtend][batch] BatchCompiler resolves symlinks, but should not #449048
When adding source path entries, compiler calls getCannonicalPath so
resolves symbolic links on UNIX. This cause e.g. AA processor to fail
because the linked source file points to a file which is probably
outside the workspace.
