'AbstractCompile' task has inputs that are related only to Java
compilation and should not used for Kotlin compile tasks.
'SourceTask' most probably will be deprecated in future Gradle releases
- https://github.com/gradle/gradle/issues/9040. Plus it has
old 'sources' with 'FileTree' type which is not stable
for task inputs snapshotting.
Another breaking change - 'destinationDir' task property is not longer
available. It is replaced by 'destinationDirectory' which uses Gradle
Provider API type.
