Description

When you create a SlingContext using ResourceResolverType.JCR_OAK you get the following error if you do not have the required dependency:

java.lang.RuntimeException: Unable to initialize JCR_OAK resource resolver factory: Unable to instantiate resourcer resolver: org.apache.sling.testing.mock.sling.oak.OakMockResourceResolverAdapter. Make sure this maven dependency is included: org.apache.sling:org.apache.sling.testing.sling-mock-jackrabbit-oak

The message contains the groupId and artifactId of the dependency you are supposed to add to your project:

org.apache.sling:org.apache.sling.testing.sling-mock-jackrabbit-oak

The problem is that this dependency does not seem to exist. I was able to solve this issue by adding the following dependency:

<dependency>
    <groupId>org.apache.sling</groupId>
    <artifactId>org.apache.sling.testing.sling-mock-oak</artifactId>
    <version>2.0.2</version>
 </dependency>

This dependency does include the class org.apache.sling.testing.mock.sling.oak.OakMockResourceResolverAdapter which is apparently the class that is supposed to be loaded by all of this.

Therefore, I would propose to update the artifact coordinates in the error message.

I added a demo project that can be used to re-produce this issue:

1. Extract the attached archive
2. Run mvn clean test
3. Error occurs
4. Uncomment dependency in pom.xml
5. Run mvn clean test
6. Error is gone
