maven-shade-plugin not including dependencies

[Désilets , Alain]

I am trying to use maven-shade-plugin for the first time to create an uber-jar 
and I can’t even get the simplest example to work.

For example, I created a simple pom based on the example at the top of this 
page:

   
https://maven.apache.org/plugins/maven-shade-plugin/examples/includes-excludes.html

The main difference with my pom is that I added a dependency to junit to test 
whether the shade plugin would include its classes in the jar. But when I run 
this command:


     mvn clean install -X

I get a build success, but when I inspect the generated jar, I don’t see the 
junit classes:


$ jar -tf spike-uber-jar-0.1.0.jar

META-INF/

META-INF/MANIFEST.MF

META-INF/maven/

META-INF/maven/org.example/

META-INF/maven/org.example/spike-uber-jar/

META-INF/maven/org.example/spike-uber-jar/pom.xml

META-INF/maven/org.example/spike-uber-jar/pom.properties

Not sure what I am doing wrong. Below is the pom file:


<?xml version="1.0" encoding="UTF-8"?>
