When i tried to generate the client library using eclipse interface i got this erro:
eclipse.buildId=M20120914-1800 java.version=1.7.0_25 java.vendor=Oracle Corporation BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=pt_BR Framework arguments: -product org.eclipse.epp.package.dsl.product -keyring /Users/renanfranca/.eclipse_keyring -showlocation Command-line arguments: -os macosx -ws cocoa -arch x86_64 -product org.eclipse.epp.package.dsl.product -keyring /Users/renanfranca/.eclipse_keyring -showlocation Error Thu May 01 19:39:22 BRT 2014 Unexpected Exception java.lang.reflect.InvocationTargetException at com.google.gdt.eclipse.appengine.swarm.wizards.GenerateSwarmApiAction$1.run(GenerateSwarmApiAction.java:82) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) Caused by: java.lang.ClassNotFoundException: com.google.api.server.spi.tools.ClientLibGenerator$Language at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at com.google.gdt.eclipse.appengine.swarm.wizards.helpers.SwarmApiCreator.createClientLibFromApiConfig(SwarmApiCreator.java:113) at com.google.gdt.eclipse.appengine.swarm.wizards.helpers.SwarmApiCreator.createSwarmApi(SwarmApiCreator.java:258) at com.google.gdt.eclipse.appengine.swarm.wizards.helpers.SwarmServiceCreator.create(SwarmServiceCreator.java:444) at com.google.gdt.eclipse.appengine.swarm.wizards.GenerateSwarmApiAction$1.run(GenerateSwarmApiAction.java:80) ... 1 more
I tried the command line at the root of the project:
$SDK/endpoints.sh get-client-lib my.package.MyEndpointsApi
And its only generated the endpoints client libs, but not the folder:
myendpointsapi-v1-generated-source
When i got back to appengine 1.9.3 it's work like a charm again..
Anyone know how to solve this?
回答1:
In line with Romin, I also think that the AppEngine SDK 1.9.4 breaks GPE 3.5.1. I had the same problem when I updated to SDK 1.9.4 a few days ago. I rolled back to 1.9.3, and the endpoints are generated successfully. I reported GPE issue no. 278.

For those who need manual installation instructions of GAE SDK 1.9.3 on Eclipse
I had the same issue and found this download link to the GAE SDK 1.9.3 https://storage.googleapis.com/appengine-sdks/featured/appengine-java-sdk-1.9.3.zip
How to manually install GAE SDK 1.9.3 in eclipse? Since I am very new to Android, I took some time to learn to manually install an eclipse plugin. Please read Konstantin's answer how-to-install-plugin-for-eclipse-from-zip
回答3:
I used this link to obtain the 1.9.3 sdk:
http://mvnrepository.com/artifact/com.google.appengine/appengine-java-sdk/1.9.3
other then that, yeah, just add via the Configure SDK properties
回答4:
For those how hasn't the SDK 1.9.3 as me, is possibile to install this SDK following the next steps:
Download the SDK from here: https://storage.googleapis.com/appengine-sdks/featured/appengine-java-sdk-1.9.3.zip
Unzip in the folder Eclipse/plugins/
Reboot Eclipse and go to Properties -> Google -> App Engine
Click on Configure SDKs
Click on Add
Browse to the folder where you unziped the plugin and click Ok.
Choose now the new SDK 1.9.3. That's all ;)

My experience was exactly the same: I couldnt generate Cloud EndPoint Libraries and the datastore didn´t work via Android.
If you want to downgrade your Google App Engine SDK after you updated it, seek into your Eclipse installation folder and look for the old SDK in plugings folder.
Afterwards you can import these old SDK to your projects from "Project Properties" and "Google/App Engine", "Configure SDK", "Add". There, you must fin the path I talked about.
Now you can chose both SDK.
I tried with 1.9.3 and it worked again.
Edited: Finally this soulution didn´t work, so I downgrade to my last stable version of Google App Engine SDK, the 1.9.2. This one worked for me.

Comment #7 on issue 278 by rdayal@google.com: GPE 3.5.1 incompatible with GAE SDK 1.9.4 - Endpoint generation fails http://code.google.com/p/google-plugin-for-eclipse/issues/detail?id=278
I hope a GPE update will come son (I CAN'T WAIT)
I gave up from Eclipse I'm using AndroidStudio now and it's generate the libraries automatically: http://rominirani.com/2014/08/27/gradle-tutorial-part-10-consuming-endpoints-in-android-code/
