Answer 1

You can also install one plugin from another using p2. You add the other installed Eclipse as an update site, and you can select the installed plug-in (after unchecking the categorization).

For update site you the following path: /path/to/eclipse/p2/org.eclipse.equinox.p2.engine/profileRegistry/SDKProfile.profile
