Java Source Attacher
Plugin Home: Http://marketplace.eclipse.org/content/java-source-attacher#.U5RmTePp0QI
Can be installed automatically through eclipse, or you can download the package manually
Today try to install the automatic installation seems very slow, download package also need to turn over the wall, I put this package on my Resources page, if necessary to download, download and then directly copied to the Eclipse installation directory under the dropins directory , And then Restart it.
