Subject: [PATCH] JAR files building Will build JAR for each 3 step separately
 when executing `gradlew build` or `gradlew jarStepX` where X is the step you
 want to export as JAR. The generated JARs are located in `build/libs`. To run
 a JAR, use `java -jar build/libs/stepX-1.0-SNAPSHOT.jar` where `X` is the
 step number
