google cloud engine android backend. Unrecognized element <servlet> error?

I've just made a basic model for the back-end of an android app using the 'add google cloud module' feature. I've created an endpoint and every time I try to run or build the project I get this error. The error before this was that it could not locate app engine-web at all which I fixed as the file name was web instead, so I changed it to app engine-web. after that it hit me with the "Unrecognized element "? full error log below.
