One-JAR

One-JAR (The original One-JAR™ project is here) is a tool to package a Java application with its dependency jars into a single jar file.

What is One-JAR-Boot?

one-jar-boot is The low-level JarClassLoader and other One-JAR bootstrap mechanisms Contains source-code for the One-JAR bootstrap classes (The description from the One-JAR web site).

So what is this repository for?

Unfortunately, it has an issue with some libraries like 'AWS SDK for Java'. When a jar file packaged by one-jar contains aws-sdk-java causes an Exception like:
