Maven discovery completed without finding any exte

问题:

I have installed eclipse 4.3 on my system and recently installed the Maven integration plugin. I get the following error:

Discovery completed without finding any extensions. Please check your network connection and try again.

The catalog url is http://download.eclipse.org/technology/m2e/discovery/directory-1.4.xml

Note: No proxies, no network issues

There is a Java update 1.7.0_45 which fixes that problem.

I was having the same issue on Mac OS X 10.8.5 with eclipse-kepler and Java 1.7_40 update. I resolved it by reverting to an older (Java 1.6) version of Java.

You can find more details here about the details causing the issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=417241

Hope this helps ~J
