Maven plugins can not be found in IntelliJ

Question

After updating IntelliJ from version 12 to 13, the following Maven-related plugins cannot be resolved:

org.apache.maven.plugins:maven-clean-plugin:2.4.1
org.a         


        

Answer 1

For me, there was a mistake in the settings.xml. I was using http:// in the url due to which it wasn't working. Once i removed it the plugins were downloaded successfully.

   http
   www-proxy.xxxx.com
