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

Anonymous User169907-May-2015

I have written a little utility to run from the command line using Java. I want to package it in a single executable jar for distribution (.jar file).

How can I make Maven package all dependency jars into my jar?

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>

</build>
and you run it with

mvn clean compile assembly:single
Compile goal should be added before assembly:single or otherwise the code on your own project is not included.

See more details in comments.

Commonly this goal is tied to a build phase to execute automatically. This ensures the JAR is built when executing mvn install or performing a deployment/release.
