Question

my problem is just like this one : User Operation is waiting for "Building Workspace"

why did it happened and how can I solve this? I have waited lots of time about this case.

right now it is look like this.

Answer 1

Eclipse can have a tendency to hang sometimes for no apparent reason (usually because of memory). Just try restarting it and see if the problem persists. I've encountered this before and restarting Eclipse or the PC altogether usually solves it.

Answer 2

I had exactly the same problem. For me helped adding '-clean' option at the first line of eclipse.ini file and restarting IDE. After adding this option eclipse clean all cached data in workspace each time it is started (that also mean it will be starting slower).
