Just a quick little note:
If you are ever behind a proxy and want to get an Extension from the STS (SpringSource Tool Suite) and it isn’t working (there is a bug in the code where it won’t use your proxy settings), you can still get the extensions by going to
HELP->Install New Software and then select
SpringSource Update Site for Eclipse then open
Extensions / STS and select the extension there.
I needed it to install the GRAILS plugin and it was a pain to find so I thought someone might need it.
