How to Build Java Project including all Dependencies as Jars

Question

I am building java project and by using maven-dependency-plugin i am able to copy all dependencies as jar in lib folder under target folder.

By using maven-jar-plugin i am able to create jar with classes/resources and manifest file.

But my desire output is that my.jar should include dependencies jar. I found couple of plugin like maven-shade-plugin, onejar-maven-plugin and maven-assembly-plugin.

But all of these provide exploded dependencies jars and i need jars dependencies as it is.
