User Operation is waiting for "Building Workspace"

Question

As the title mentioned, I have developed a simple NFC app in eclipse and I am trying to run it in the mobile device to debug my code. However, when I try to run it, this message came out, the problem even cannot launch. It said one operation left, but it seems like it has stopped. Have anyone met the similar problem before, or anyone know what is happening here?

Answer 1

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).

Answer 2

For me the clean option didn't work and I didn't want to reset the workspace. Fortunately for me another solution worked:

1. Disable automatic builds (uncheck menu item Projects -> Build Automatically)
2. Restart IDE (I had to kill it from command line)
3. Close all projects
4. Restart IDE (this time it should close without problems)
5. Open projects that you need to work on (everything should be fine now)

Oh yeah, I had the clean option in the eclipse.ini the entire time. Not sure if that is necessary, but it might be good to try that option first anyways.

Answer 3

I had to disable the automatic build option from the Eclipse and restart it. This made it work for me.
