I faced a problem (I had a checkstyle-config.xml that, should not be included in the final assembly). A solution below worked for me:
Adding the **resources** section made my project-jar-with-dependancies.jar not containing checkstyle-config.xml file
Simplified pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<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">

Taking Unanswered's answer and reformatting it, we have:
<!-- language: xml -->
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>fully.qualified.MainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
</plugins>
</build>
Next, I would recommend making this a natural part of your build, rather than something to call explicitly. To make this a integral part of your build, add this plugin to your `pom.xml` and bind it to the `package` lifecycle event. However, a gotcha is that you need to call the `assembly:single` goal if putting this in your pom.xml, while you would call 'assembly:assembly' if executing it manually from the command line.
