webstart maven plugin with dependencies

Question

My boss told me to work with the Maven Web Start plugin to generate a JNLP and a signed JAR.

The problem is no matter how I try I couldn't make a JAR containing my dependencies.

I'm always facing a ClassDefNotFound Exception

build output

please add your build output here (and possibily the directory structure created and its content, notably the content of the lib/ folder, if it went that far)

Answer 1

The webstart-maven-plugin doesn't create a JAR with the dependencies, it creates a JAR along with the JARs of dependencies in the lib/ folder.

If you want to package everything in one JAR, you'd need to use the maven-shade-plugin.
