An inotifywatch -r on the ~/.eclipse/org.eclipse.platform_3.5.0_155965261/plugins directory, and subsequently starting eclipse revealed that eclipse was not even trying to read any plugins from that directory. Apparently something in Ubuntu 10.10 build of Eclipse has changed which causes it ignore the previously installed plugins. So I moved out my old ~/.eclipse/org.eclipse.platform_3.5.0_155965261/ directory to /tmp. Restarted my Eclipse and reinstalled my ADT and other plugins. Here are the steps:
- Exit eclipse if running
- Delete ~/.eclipse/org.eclipse.platform_3.5.0_155965261
- Start eclipse
- Open Help->Install New Software
- Install GEF plugin from http://download.eclipse.org/tools/gef/updates/releases. Note that GEF is required for ADT
- Install ADT plugin from https://dl-ssl.google.com/android/eclipse
You should have a working ADT in Eclipse on an upgraded Ubuntu 10.10.
