Project Error (Eclipse) when creating Google Cloud Endpoint in GAE

I created a simple project with GAE and i put in my package 'model' the PMF.java (Persistence Manager Factory Class) and a class (Employee.java). After right-clicking the Employee class on Google->Generate Cloud Endpoint Class, the plugin correctly generate my EmployeeEndpoint, but after created that it appears an error on:

war->WEB-INF->lib

for this jar:

appengine-api-labs.jar
appengine-endpoints.jar
appengine-endpoints-deps.jar

And opening the ErrorLog of Eclipse, it just says:

An exception stack trace is not available

So clicking on the project to: Google->Generate Cloud Endpoint Client Library an error appears:

Error in Generating Client Libraries

with this message:

An error occurred when attempting to generate the client libraries

So, now that i'm facing this error, what could i do to solve the problem? Thank you so much in advance

[EDIT Error Log]:

Message:
Unexpected Exception

Re-name the endpoint class file to the standard format, Eg: "Earth.java" then it would work fine.

I had exactly the same problem using Eclipse 4.3 with GAE version 1.9.6.

When I reverted to GAE version 1.8.8 the problem was solved immediately.

To revert right click your project -> Properties -> Google -> App Engine and choose an older version. I read somewhere that the problem came in since version 1.9.4.
