gradle-launch4j | A gradle-plugin to create windows executables with launch4j | Plugin library

According to this oracle docs there is a conventional java app packaging along with runtime JRE. (Self-Contained Application Packaging)

I know that there is this thing (Launch4j gradle plugin) but I'd prefer to have a bat/sh executables along in the package.

Going through gradle docs and googling I can not seem to find is there is a way to teach gradle to package desktop app with JRE. Is there?

Please note: Although I specifically mention two Gradle plugins here, this is 100% a question about understanding task dependencies in Gradle, and does not require any knowledge of the individual plugins (I think)!

I have a project that will use two Gradle plugins:

• The Gradle Shadow plugin, which will produce a self-contained "fat jar" (basically a large jar with all my classes plus the classes of all my transitive dependencies, which then allows me to just run java -jar myapp.jar without having to manage the jar's external classpath, etc.). This will produce a fat jar at build/libs/myapp.jar; and
• The Gradle Launch4J plugin, which uses Launch4J under the hood to convert a jar into a native executable (EXE, etc.). Obviously the fat jar has to be created prior to the Launch4J tasks run, otherwise they'll have nothing to wrap inside of an EXE!

Here's my build.gradle:
