This information is hidden unless you own the entry on the marketplace. However you can obtain it using the marketplace API. For instance getting the details on the OS X Eclipse Launcher, by issuing curl http://marketplace.eclipse.org/node/364668/api/p on the command line and you'll get all the details in the form of XML. The update site URL is in updateurl, and the feature(s) are listed in ius. Replace the number with the identifier of the entry in the marketplace. You can find it by looking at the URL assigned to the Install link button.

February 7, 2024 - Those using these non-versioned URL do not need to change their software repository lists or scripts. In other words, the contents are identical to their current, versioned counterparts, but the URL stays the same. These repos go well together with the latest release train repo: http://download.eclipse.org/releases/latest

May 24, 2017 - Look at this page for information about implementing what's called a repository provider for Eclipse. There's a repository provider for each version control "product": there's one for Git, one for SVN, etc.

Can you connect to internet at all through Eclipse?

  • Open the internal webbrowser. In Eclipse: Window -> show view -> Other -> General: Internal web browser.
  • Look up any normal adress, is it working?

Can you connect to another update site? Try for example Eclipse Emma: http://update.eclemma.org/ Do you see anything there?

What are your proxy preferences? Go to Window -> preferences -> General: Network connections.

The active provider:

Specifies the settings profile to be used when opening connections. Choosing the Direct provider causes all the connections to be opened without the use of a proxy server. Selecting Manual causes settings defined in Eclipse to be used. On some platforms there is also a Native provider available, selecting this one causes settings that were discovered in the OS to be used.

If internet is working fine outside of Eclipse, try changing to Native. After that, try Direct.

I have encountered problems where an update site would not load, then I had to remove it and add it again. This forces Eclipse to reread the contents of the site even if it has a cached copy. So, if you still get no connection to the indigo update site, but everything else is working, try that. Go to Window -> Preferences -> Install/update: Available Software sites. Then remove and add the indigo site. Just remember to copy the adress so you can add it again.

As suggested in a comment below by @lostiniceland, this is a simpler way to achieve the above:

Goto Window -> Preferences -> Install Update -> Available Software Sites => select the entry and click the "Reload" button to the right. This is sometimes also helpful when you have a local updatesite for testing custom plugins

I had the same problem and resolved it by

  • Deleting the cache directory \eclipse\p2\org.eclipse.equinox.p2.repository\cache
  • Refreshing the repositories.
    • Preferences -> Install Update -> Available Software Sites => select the entry
    • Click the "Reload"

Typically used for authenticated write access to the repository. Note: If you are behind a firewall you may need to configure your proxy settings (Preferences > General > Network Connections). Many HTTP proxies are configured to block URLs containing a username (and/or password) like e.g. http://fred:topsecret@egit.eclipse.org/egit.git hence it's recommended to use the user, password fields at the bottom of the wizard page, the credentials will be transmitted as HTTP headers.
