Devel: https://repo1.maven.org/maven2/io/arrow-kt/arrow-fx/0.12.1/arrow-fx-0.12.1-sources.jar
Deploy: https://repo1.maven.org/maven2/io/arrow-kt/arrow-fx/0.12.1/arrow-fx-0.12.1.jar#to

I ran the map_deploy_to_develop:Java pipeline in SCIO, but all .class files found in deploy side don't have match with the devel:

• All the .class files that ends with Kt.class in deploy have corresponding .kt extension files found in the devel
• Others .class files that don't ends with Kt.class are likely an inner class of a .kt files
