Gradle-lean

A gradle plugin that minimizes dependency jars.

Motivation

We have maven-shade to help us minimize jars. But when it comes to gradle, the similar plugin gradle-shadow doesn't do the favor. This project is to provide a lightweight way to reduce the size of an java application distribution package on the fly.

This plugin depends on JavaPlugin and ApplicationPlugin.

• for installDist, jars under install/$PROJECT_NAME$/lib/
• for distZip, jars under /lib/ inside package

will be minimized by respective lean tasks.

Todo list:

• resolve current issues
• lean for distTar
• customized jars

How to use:

Add gradle-lean plugin to build:

plugins {
    id "com.github.gradle-lean" version "0.1.2"
}

Execute gradle tasks:

• installDistLean will trigger installDist and then minimize the jars.
• distZipLean will trigger distZip and then minimize the zip archive.

Exclusions

Class or dependency jar exclusion can be set in build.gradle:

leanConfig {
    excludedClasses = [
            "com.google.common.cache.*",
            "com.google.common.io.ByteSink"
    ]
    excludedDependencies = [
            "com.google.jimfs:jimfs:1.1"
            //or "com.google.jimfs:jimfs:*"
    ]
}
