google cloud storage

I'm trying to follow GCS getting started guide - https://cloud.google.com/appengine/docs/java/googlecloudstorageclient/getstarted

it says that I should download the client library, i did it with git.

then it says:

In the Libraries tab, click Add External Jars. You must add the following JARs:

appengine-gcs-client.jar from wherever you installed the Cloud Storage client library

guava-15.0.jar from wherever you installed the Cloud Storage client library

joda-time-2.3.jar from wherever you installed the Cloud Storage client library

appengine-testing.jar from the App Engine install subdirectory /lib/testing.

appengine-api.jar from the App Engine install subdirectory /lib/impl.

appengine-api-stubs.jar from the App Engine install subdirectory /lib/impl.

but there are absolutly no jars in the download,

what am I missing??

Edit: I manage to find the missing jars on the web, now i get:

Seems like this guide was never actually tested, and is a complete waste of time, or what?

I got into the same troubles and what worked for me:

Updated the libraries (appengine + appengine-testing) to the same version

I used to have appengine version 1.9.18 and appenginte-testing version 1.4.0. Now I have both version 1.9.25 (the latest at the moment)

Added all necessary libraries

appengine-api-labs and appengine-api-stubs were missing

My build.gradle config now contains this:

dependencies {
    appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.25'
    compile 'com.google.appengine:appengine-endpoints:1.9.25'
    compile 'com.google.appengine:appengine-endpoints-deps:1.9.25'
    compile 'com.googlecode.objectify:objectify:5.1.5'
    compile 'javax.servlet:servlet-api:2.5'
    testCompile 'junit:junit:4.12'
    testCompile 'com.google.appengine:appengine-testing:1.9.25'
    testCompile 'com.google.appengine:appengine-api-labs:1.9.25'
    testCompile 'com.google.appengine:appengine-api-stubs:1.9.25'

}
