I'm using Eclipse Luna and as I'm working on two different computers, I wanted to install the project I'm working on on my new laptop. I downloaded the git-repositories needed and wanted to set the target platform before starting to implement. But when I click on luna.target, the resolving target platform fails and every locations shows up "Unable to locate installable unit".
As I do some research in the WWW, I found that it's probably a bug in eclipse and can be resolved by restarting/updating/cleaning the project... But all of these steps didn't work for me.
The locations themselves should be right, because resolving the target platform on my first computer always works.
I'm desperate, please help me! Thank you in advance :-)
