Why am I getting this problem ?

Answer 1

I'm the creator of eclipse-pmd, the plugin you are trying to install. I tried to install it myself just now and it worked without any problems. So I can only guess what could be the problem in your case:

The repository was temporarily not available
Simply try again.

You are using a (very) old version of Eclipse
The plugin requires Eclipse Indigo (3.7) or later. I tried to install eclipse-pmd with Indigo and Luna just now and it worked both times.

Run Eclipse with Java 7
You need to run Eclipse with a JRE 7 or later. There have been problems during the installation with people using an older JRE in the past. However they could finish the installation but Eclipse silently refused to load the plugin (this has been fixed a few versions ago though).

Proxy configuration
Although unlikely as you came this far, please open the proxy configuration in Eclipse and check if the settings are correct and the domain is accessible.

If you tried everything I suggested above and are still not able to install the plugin, please head over to the project's Github page and open an issue .
