>From Android-M, the default compiler for java source code is changed from 
javac to jack. As explained in https://source.android.com/source/jack.html, 
jack does not generate the intermediate classes.jar files. It directly 
generates classes.dex files from *.java files.

Furthermore, using such intermediate files (such as classes.jar) is not a 
very good idea. As an app developer, you should depend on SDK/NDK only.
