Ok I fixed the problem, it was probably a corrupted jar, i deleted all of the jars and downloaded them with maven again and it worked fine.

As saiyr stated in the comments, Google Cloud Endpoints v1.1 has been completely deprecated and has stopped serving traffic and that is the reason for the errors I was having. I solved this problem by migrating to cloud endpoints v2, the process is as easy as following the guide in the migration docs but here are some issues I had with Migration and how I fixed it.

1. Google guava library has to be updated to a version greater than version 19, using version 19 or lower could result in the application throwing reflection errors when handling requests.

2. If you have multiple service classes they have to be added to the web.xml file as service parameters while declaring the com.google.api.server.spi.EndpointsServlet Servlet. for some reasons listing only one service class worked for me in cloud endpoint 1.0 Api docs and routes were generated for all the service classes I had without declaring everyone of them explicitly under the com.google.api.server.spi.SystemServiceServlet Servlet, I think it has something to do with Objectify filters though. See the Docs for more info

3. Since the Google App Engine Java 7 runtime is deprecated too, I decided to migrate to Java 8 but unfortunately the library I used to abstract the process of connecting to datastore (Objectify) appears not to work with the Java 8 runtime, I would look into this later, but reverting back to Java 7 runtime worked for me and the application is back up and running.

Update: The issue I faced migrating to Java 8 runtime had nothing to do with Objectify, the library I used for encrypting passwords (BCrypt) was the issue, it just did not work on the Google App Engine Java 8 runtime, I had to switch to the Encryption library in spring security.

You'd better open in Eclipse your pom.xml file and switch to the "dependency hierarchy" tab. Look for the undesired library (type in "serlvet" in the filter) and add exclusion on it through the context menu. This will modify your pom.xml file.

The code mentioned in the anwser you referred works, the prefix should look like this:

Since you're using Java: in case you are willing to try google-cloud-nio, it has a listBuckets method that goes like this:

I just had a similar problem, to solve it I googled and found out people suggesting to add 'google()' Gradle could not find dependency com.google.android.gms:play-services, but probably you have already done it since you followed the instructions.

In my case it wasnt enough, I noticed that i was using something that required a higher SdKVersion, so i just had to increase it to the right minSdkVersion.

After revisiting this, due to recent demand I figured it out. gsutil has a bug, I read about its somewhere at github. When I upload the file via storage browser or the python client libraries it works.

the "google-cloud-storage" seems to be much more "alive":

[ google-cloud-storage

After removing all dependencies of guava-jdk5 from following packages solved the problem:
