Atfer playing around a little with my USB drive I somehow managed to stuff up Eclipse and every time I attempted to start it, it would crash with an out of memory error. Eventually I read that you can use the “-refresh” option if you start eclipse from the command line to perform a global refresh of your workspace. The first time I tried this it had no effect, only after I deleted the contents of .metadata folder was the problem fixed by using this start up option. Another issue I stumbled across was that not all of the plugins I had installed were showing up. Starting up eclipse with “-clean” forced eclipse to reload the plugins and XML buddy which was missing was now available again.
