One-JAR™
One-JAR™ 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:
Exception in thread "main" java.lang.reflect.InvocationTargetException
