Where to find google app engine JCache dependencies - google-app-engine

Question

The JCache documentation https://cloud.google.com/appengine/docs/java/memcache/usingjcache describes how to use the api, however there is no mention of where to find the dependencies. I guessed on
<dependency>
<groupId>javax.cache</groupId>
<artifactId>cache-api</artifactId>
<version>1.0.0</version>
</dependency>
which resolves all the classes except for CacheFactory. I found some old references to source forge but no mention of how to resolve these classes.
Maven error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project appengine-helloworld: Compilation failure: Compilation failure:
[ERROR] /Users/me/Google Drive/dev/app/src/main/java/com/example/appengine/helloworld/HelloServlet.java:[26,19] cannot find symbol
[ERROR] symbol: class CacheFactory

Answer 1

This problems seems to originate from the use of the helloworld sample app that is generated when you follow the Hello, World! in 5 minutes guide https://cloud.google.com/appengine/docs/java/
I created a new project with the mvn archetype command described here https://cloud.google.com/appengine/docs/java/tools/maven#maven_requirements This creates a skeleton project with the appengine jar and resolves the jcache stuff
https://cloud.google.com/appengine/docs/java/tools/maven#maven_requirements
Specifically, the dependency is
<dependency>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-api-1.0-sdk</artifactId>
<version>${appengine.version}</version>
</dependency>
