I'm unable to get the Central Maven repo index. I'm running Netbeans 7.0.1 and have tried rebooting my PC, rebooting Netbeans 4 times and alternate mirrors. It sits at 0% and never goes anywhere and never throws an error. I'm unsure what to try or what to investigate to try to determine the problem.
Try to move the local-Repository-path to another place, in the file: conf/settings.xml
Also check maven's configuration.
