eclipse work space error

[LUYA]

Hi I'm a newbie in this modding world, I downloaded JDK and eclipse watching some You tube  tutorials . I followed every thing they said but I have some matters in opening the eclipse...

when I set the work space to the forge folder where I made and set the build environment, it just keep getting errors and telling me to look at the .metadata/.log files of the forge folder.

So I opend the log file, but I can't understand it. Can anybody help me with this errors? it will be nice if you tell me how to solve it
