I am facing a situation where my eclipse indigo is "Unable to update index for central|http://repo1.maven.org/maven2".

I am using an external Maven 3.0.3 installation and m2eclipse configured with Eclipse Indigo and I am definitely not behind any proxy.

Also my networking configuration in eclipse is all set to direct and I am still unable to update the indices.

What may I have overlooked? I have searched on Google and other forums but am unable to resolve it.

From Wojtek's link.

  1. Close Eclipse
  2. Delete workspace_location/.metadata/.plugins/org.maven.ide.eclipse/nexus
  3. Delete workspace_location/.metadata/.plugins/org.eclipse.m2e.core/nexus
  4. Go to Window->Preferences->Maven and enable checkbox named “Download repository index updates on startup”.
  5. OK and restart Eclipse.
