How can I create an executable jar with dependencies in sub folder in jar using Maven?

Question

How can I create an executable jar with dependencies in sub folder in jar using Maven?

The following pom.xml will make a executable jar with the dependencies in the root but what if I wanted all the dependencies in a sub-folder in the jar so its easy if someone else would want to look in the jar. How can I change the following pom.xml file:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

You want to look at the Maven Shade plugin.

If you want a full web app in a single jar there are a couple of options:

• Do what DropWizard does which is an example maven shade + jetty.
• The Tomcat version +2 Maven plugin
• Winstone
