[1.7.10] crash! unable to start minecraft! [SOLV'D]

[sigurd4]

i can't run minecraft from eclipse, and it does not seem to have anything to do with my code. i had this problem since i set up the workspace, so there must've been something i have forgotten to do in the setting up process. this is my crash log:

I've had the same problem, but I don't know how to set GradleStart as my main class. Can someone explain this?
