Next Time when I tried to download again I got the error as:

No repository found at http://download.jboss.org/jbosstools/updates/stable/kepler/.

There is no problem with my internet connection, but I am not sure why such errors are coming while installing software JBoss Tools.
Please suggest any solution.

Answer 1

I've just faced the same problem, and I'm using a direct connection. Checking the network connections, I've noticed that it was set to "Native" (probably Eclipse Kepler's default, since my installation is rather new).

It was solved by changing Network Connections "Active Provider" from Native to Direct .

Path to network configuration in Eclipse: Windows>>Preferences>>General>>Network Connection

Answer 2

Same problem occurs with Eclipse Luna as well. Setting Active Provider to Direct solves the issue.

Answer 3

For me the above answer did not work because we are using a proxy to connect to the internet. So our settings are manual for the network

But I resolved it:

1. Go to Help --> Install New Software .
2. Add the repository link http://download.jboss.org/jbosstools/updates/stable/kepler .
3. Choose Hibernate Tools from the options.
4. Accept the licence and proceeding with the installation.
5. Restart Eclipse and Hurray!
