Subject: [PATCH] Fix Javadoc generation.

Accessing task providers (like javaCompileProvider) at sync time is not
possible. That's why the source sets of all generateJavadoc tasks is empty.

The set of source directories can also be accessed directly through the static
sourceSets field. Combining these allows to statically provide the relevant
source files to the javadoc task without needing to access the run-time task
provider.
