Single Jar Application Gradle Plugin

This gradle plugin let you create fat-jars without repacking the libs, they are kept intact inside the lib folder of the single jar.

The classes are loaded by a custom class loaded that is added to the resulting jar which is capable of loading and providing resources of jars that are inside the same jar.

Usage

Add the code snipped bellow in your build.gradle or build.gradle.kts file.

The file JAR file will be generated when you build the project or execute the new distSingleJarApp task.

The single jar application file will be located at the build/distributions folder by default.

Important note: The jar which is created in build/libs folder is left untouched, it's not the same jar as the one inside the build/distributions folder.

If you open the jar with a ZIP file viewer such as 7-Zip you will be able to find all the dependencies inside the META-INF/lib folder and a new synthetic class named: your.package.YourMainClass$SingleJarLauncher (it uses your main class name as base).
