Getting "No Repository Found" error in Eclipse (Ganymede) while trying to install google plugins (GWT)

Question

I'm trying to install the Google Web Toolkit for Eclipse (Ganymede), and I'm getting the following error.

An error occurred while collecting items to be installed

What could this error mean, and how do I install the plugins. It's a new install of Eclipse and Vista 64bit. I used "http://dl.google.com/eclipse/plugin/3.4" as the google plugin location.

Answer 1

Looks like your eclipse mirror was corrupt. Use another one.

Answer 2

OK I got it.

I'd installed Eclipse Classic, and it didn't like it. Since then, I've uninstalled classic and installed "Eclipse Java EE" and the update worked.

Answer 3

I had the same problem, what fixed it is to change the updating system that Eclipse used. I am using Eclipse 3.5 and the default updating system is P2 (http://wiki.eclipse.org/Equinox%5Fp2%5FGetting%5FStarted). Try going into Prefereces->General->Capabilities-> check the box next to Classic Update. This fixed it for me.
