AEM Mocks: Problem with ResourceResolverType.JCR_OAK

Question

I am using AEM Mocks (with JUnit 5). I create my context as follows:

private final AemContext aemContext = new AemContext(ResourceResolverType.JCR_OAK);

Note the use of JCR_OAK. Everything works fine if I try to use JCR_MOCK instead. When trying to inject certain services, I get the following error:

java.lang.RuntimeException: Unable to initialize JCR_OAK resource resolver factory: Unable to invoke method 'activate' for class org.apache.sling.resourceresolver.impl.ResourceResolverFactoryActivator

I already tried the advice described here - inverting the sling-mock-oak and uber-jar dependencies - but this can't be done. If sling-mock-oak comes before the uber-jar, other errors are thrown.

Can someone please tell me why I get the error above?

Thank you!

I was able to get my node property request's working by switching to ResourceResolverType.JCR_MOCK instead, and correcting my test decencies to match the pom.xml in the example https://github.com/adobe/aem-guides-wknd
