I didn't understand anything.

Can anyone help me in this.

I'm really stuck

Did you try running eclipse.exe -clean?

Any cached data used by the OSGi framework and eclipse runtime will be wiped clean. This will clean the caches used to store bundle dependency resolution and eclipse extension registry data. Using this option will force eclipse to reinitialize these caches.

its clearly saying that some dependcies plugins were not been installed, so please reslove the dependency .

Better you post the same in Eclipse forum, they will provide you solution.
