Q: Getting "No Repository Found" error in Eclipse (Ganymede) while trying to install google plugins (GWT) I'm trying to install the Google Web Toolkit for Eclipse (Ganymede), and I'm getting the following error.

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. 

A: 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. 

A: In my case I have archive software sites witch be deleted and updater say about this.
Check Windows -> Preferences -> Available Software Sites. In this list should not be archive sites witch deleted. Then restart eclipse.

A: I just clean eclipse and run it worked.
in command prompt type eclipse -clean
This cleans the installation of eclipse and helps to run

A: I had this problem today. I found this helpful link which helped. Basically make sure all your sources' URLs end in a slash (/), and add them if they are missing.
I also went through all the sites and clicked the Test Connection button (I think that's what it's called) on each one to see if there was something wrong, and they all returned a successful result.
After that, suddenly I was able to install the features and plugins that had failed with the "No repository found" errors before.

A: No necessarily to do all those import export and stuff.
Eclipse has a problem with itself. But it can be solved with a simple startup of
cmd> eclipse.exe -clean
it will take awhile to startup but eventually it worked for me. coz partially sometimes eclipse has problem unzipping files or so n partial files unzipped.

A: 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_p2_Getting_Started).  Try going into Prefereces->General->Capabilities-> check the box next to Classic Update.  This fixed it for me.

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

A: I got this error when trying to update the Google plugin (clicking on the 'updates available' popup).
Reviewing my update sites, it turned out that the main Google update site (http://dl.google.com/eclipse/plugin/3.5) was missing, although I doubt I had removed it.
Simply re-adding it solved the problem.

A: To be honest it doesn't work for me, until I removed all oracle's url from Available Software Sites as motioned in eclipse forum, I still have some URLs without / at the end though.

A: I got a similar error message while installing the Jboss Tools.
In the install dialog, I unchecked the option "Contact all update sites during install to find required software" which solved the problem.

A: I needed to remove an Oracle URL from update sites as well to get GWT plugin to update. I am using Eclipse Kepler with the following URL for GWT - https://dl.google.com/eclipse/plugin/4.3

A: In case it helps anyone, none of the solutions provided here worked for me (on Eclipse Luna). Had to update plugin via Marketplace.
