Realm-java: Android Gradle Plugin 3.6.0: Realm Gradle plugin should process R classes from jar

[gavra0]

Starting with Android Gradle plugin 3.6.0-alpha01, R.java is not generated any more, and R clasess are compiled separately from the rest of the sources to R.jar e.g. ./app/build/intermediates/compile_and_runtime_not_namespaced_r_class_jar/debug/R.jar.

This means that the RealmTransformer should be able to process project classes coming from both directories and jars. Looking at implementation of BuildTemplate.categorizeClassNames it seems that classes coming from jars are in not processed.

Thanks. Yes, we should fix this.

I can reproduce with 3.6.0-alpha05 and the /examples/multiprocessExample

Many of the other example projects seem to work fine though, which strikes me as a bit odd.

Problem was that the JAR files were not correctly copied to the output folders again which is why the transformer worked correctly, but the project crashes at runtime. This should be fixed in #6575

fixed by #6575
