Eclipse Project Build Stuck at 43%

Hi friends,

I have created a UI5 project and was referring to sap-ui-core.js from the HANA Cloud repository.

I decided to make it self sufficient, hence decided to add the resources folder from the Demo Kit.

Now I added the folder to the project, but the build never completes. It is always stuck at 43%.  I tried to do a Clean, which is again stuck at 43%

It is stuck at "Validating <project name>/WebContent/resources/testsuite/js"

I am using Eclipse Juno Service Release 2.

Any help is appreciated.

Thanks

Krishna
