Generate Cloud Endpoint Client Library

Aging, this buggy, troublesome, terrible ..... Eclipse brings another nightmare to me.

I followed each steps carefully in the tutorial, and I even couldn't find the error log in Eclipse yet.

Where is the Error Log exactly?

Okay, eventually, I found the log file in my workspace C:\WorkSpace\.metadata

I must admit Eclipse has broken all my personal records, and has become the worst and the most unproductive IDE at all times.

The exact error is .... holy sh*t

After spending a whole day, I decided to download the latest ADT SDK, and finally I could build my every first endpoints class by using the GPE. In addition, I found the error log

Yet, Eclipse won't let my headache go away. For sure, I have to reset and download all libraries, and, this time, the AVD manager and the SDK manager were gone missing in Eclipse interface.
