Eclipse hangs on loading com.android.ide.eclipse.adt

參考自: http://stackoverflow.com/questions/8972034/eclipse-hangs-on-loading-workbench

rm -r workspace/.metadata/.lock

Make sure to start eclipse using ./eclipse -clean -refresh

還是不行的話，用下面的

rm -r  workspace/.metadata/.plugins/

All Plugins actually did work after that. Some settings gone. You can then use Import... to import all your existing projects at once. Deleting workspace/.metadata is the last choice, but works. You can keep workspace/.metadata/.mylyn if you don't want to loose your tasks.
