Eclipse updates not working

Question

I have installed Eclipse 3,6 on 64 bit Windows platform. When I try to connect to update sites by going to Help->install new software it gives following error:

Unable to connect to repository 
http://download.eclipse.org/releases/galileo/content.xml
Connection refused: connect

I have tried all available sites - they all give me the same error. Dialog box shows: Provision exception.

Any idea what's happening?

Answer 1

Well, try to enter this website: http://subclipse.tigris.org/update_1.6.x

If that link works, then it's not your fault. I've tried your link, and it doesn't work for me either.

If the link I gave you doesn't work either, then the problem is on your side and you need to check your network settings.

Answer 2

Maybe you're behind a firewall, and need to access the web through a proxy. Have you set a proxy in your web browser? If so, you need to set the same proxy in Eclipse (go to Preferences > General > Network connections).

Answer 3

If you are behind a firewall, have set the proxy settings in the preferences correctly and it's still not working, Try setting -Dsun.net.client.defaultReadTimeout=<"amount in ms, e.g. 30000"> in the eclipse.ini worked well for me. It looks like Eclipse has a quick timeout on that updatesite search. Some proxys can slow the process down by a few seconds and you get a timeout before the updatesite is loaded completely

Answer 4

1. In Eclipse (go to Window > Preferences > General > Network connections).
2. Select "Active Provider" as "Manual".
3. Select HTTP and click edit.
4. Enter the host and port
5. Select "Requires Authentication" and enter the username and password.

6. Repeat Step 1 to 5 for Https.

7. In "proxy bypass" section click "Add host"

8. Enter http://download.eclipse.org/releases/galileo/content.xml and OK

After spending an entire week with the issue, this solution finally worked for me
