Documentation Update for Cache Location on macOS 
This threw me a bit, as I copied and pasted trying to clear the cache on macOS and this path was wrong.

Warp

Warp lets you create self-contained single binary applications making it simpler and more ergonomic to deliver your application to your customers. A self-contained binary is specially convenient when the technology you use, such as Node.js, .NET Core, Java and others, contain many dependencies that must be shipped alongside your application.

Warp is written in Rust and is supported on Linux, Windows and macOS.

Quickstart with Java

Linux

Create a Hello World application

Create HelloWorld.java:

// HelloWorld.java
public final class HelloWorld {
  public static void main(final String[] args) {
    System.out.println("Hello, world. ");
  }
}

Test that it works:

$ javac HelloWorld.java
$ java HelloWorld
Hello, world.

We need to bundle this as a .jar:

$ jar cvfe app.jar HelloWorld HelloWorld.class
added manifest
adding: HelloWorld.class(in = 428) (out= 290)(deflated 32%)
$ java -jar app.jar
Hello, world.

Download a JRE

There are prebuilt JREs over on AdoptOpenJDK.

Here we use JRE 8:

wget -N https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u202-b08/OpenJDK8U-jre_x64_linux_hotspot_8u202b08.tar.gz

Unpack it:

tar -xvf OpenJDK8U-jre_x64_linux_hotspot_8u202b08.tar.gz

Create a bundle

We need to create a folder containing: our compiled code, the JRE and a launch script.

mkdir bundle
cp -r ./jdk8u202-b08-jre ./bundle/jre
cp app.jar ./bundle/app.jar
touch bundle/run.sh
chmod +x ./bundle/run.sh

Finally, we to write run.sh. This script will run our .jar using the bundled JRE.

Here are the contents of ./bundle/run.sh:

#!/usr/bin/env bash

HERE=${BASH_SOURCE%/*}

"$HERE/jre/bin/java" -jar "$HERE/app.jar" "$@"

Test the bundle:

$ ./bundle/run.sh 
Hello, world.

Download warp-packer

If you save warp-packer in a directory in your PATH, you only need to download it once.

$ wget -O warp-packer https://github.com/dgiagio/warp/releases/download/v0.3.0/linux-x64.warp-packer
$ chmod +x ./warp-packer

Create your self-contained application

$ ./warp-packer --arch linux-x64 --input_dir bundle --exec run.sh --output app.bin
$ chmod +x app.bin

Run your self-contained application

$ ./app.bin 
Hello, world.

How it works

Warp is a multi-platform tool written in Rust and is comprised of two programs: warp-runner and warp-packer.

The final self-contained single binary application consists of two parts: 1) runner and 2) the compressed target application executable and dependencies.

warp-runner is a stub application that knows how to find the compressed payload within its own binary, perform extraction to a local cache and execute the target application.

The extraction process only happens the first time the application is ran, or when the self-contained application binary is updated.

warp-packer is a CLI application that's used to create the self-contained application binary by downloading the matching warp-runner for the chosen platform, compressing the target application and its dependencies, and generating the final self-contained binary.

Performance

The performance characteristics of the generated self-contained application is roughly the same of original application, except for the first time it's ran as the target application and its dependencies have to be decompressed to a local cache.
