What does about Eclipse ' s "No repository found containing: ..." error messages?

1. As Mauro said: "You had to remove and re-add the Eclipse Project Update site, so, it metadata is re-calculated."- Works as workaround

2. Another workaround I found, is to edit the pre-defined URL of link by adding just a trailing "/" to the Update site URL.

3. The third workaround I discoverd accidentaly is to does nothing, but to uncheck the ' Contact all update sites during install To find required software ' before checking the URL link.

Option #2 worked for me. I went Window > Preferences > Install/Update > Available Software Sites to, then for each enabled site I added a / to the end of the URL (if it wasn ' t there already) and then click Ed Reload .
