Gcm_defaultSenderId cannot be resolved

Question

I am trying to run a GCMsample application here in my Eclipse.

I do not use Android studio and I do not have a plugin gradlein my eclipse.

After importing the eclipse client application, GCMI get the error message:

gcm_defaultSenderId cannot be resolved or is not a field

I do not want to switch to Android studio.

• How to remove this error and run the application?

• If I need to install gradle, which plugin should I use in my Eclipse-MARS?

PS - I have never used gradle before.
