-after building an ext plugin with Plugin SDK, the ext-impl.jar contains other jar files, which is illegal. Java refuses to load the file.

• the generated xml, in my case "ext-hello-world-ext.xml" contains subversion svn files which should be filtered out.
  -hello-world-ext sample from http://issues.liferay.com/browse/LPS-6341 is out of date and does not compile.
