GitHub - cdsap/FatBinary: Gradle plugin than generates a fat binary with all the dependencies of a given Project

FatBinary

Gradle plugin than generates a fat binary with all the dependencies of a given Project.

A common use case is to generate tooling from jvm projects that could be portable to ci/local environments.

Include plugin in your root build.gradle(kts) file:

plugins {
  id("io.github.cdsap.fatbinary") version "1.1.0"
}

Defines the main class of the application and the binary name

fatBinary {
    mainClass = "com.example.Main"
    name = "binary"
}

Finally execute the binary:

./binary

Publish the plugin locally, build the e2e consumer binary, and smoke-test it (TaskReport-style):

./scripts/test-cli-matrix.sh

To exercise multiple JDKs on your machine, pass their JAVA_HOME paths:

./scripts/test-cli-matrix.sh "$JAVA_HOME" /path/to/jdk-21 /path/to/jdk-25

The idea came from the Diffuse library where the binary is updated with the java command execution:

binaryFile << "#!/bin/sh\n\nexec java \$JAVA_OPTS -jar \$0 \"\$@\"\n\n"
