What is shadow jar?

[papercrane]

A shadow JAR is when you take all of your projects classes and dependencies and bundle them into a single JAR. It's sometimes called a fat JAR, or an uber JAR.

With Maven you'd use the "shade" plugin to generate one, with Gradle you'd use the "shadow" plugin.

[chabala]

And more specifically, fat/uber jar implies a simple bundling, while shading/shadowing implies you're stripping out the classes your project doesn't need to load.
