A uber-jar is a mega jar that contains all the dependencies. It's usually also a runnable jar.

Here are the steps to create a uber-jar:

1) First of all you need a build section in your pom to make your jar runnable:

       <build>
              <plugins>
                     <plugin>
                           <groupId>org.apache.maven.plugins</groupId>
                           <artifactId>maven-assembly-plugin</artifactId>
                           <configuration>
                                  <archive>
                                         <manifest>
                                                <mainClass>uk.co.davisfiore.MainClass</mainClass>
                                         </manifest>
                                  </archive>
                           </configuration>
                     </plugin>
              </plugins>
       </build>

2) Then you need to generate the uber file, running the following command:

       mvn assembly:assembly -DdescriptorId=jar-with-dependencies

In output you should get something like this: my-project-0.0.1-SNAPSHOT-jar-with-dependencies.jar

3) Now you can run your jar without passing a long list of dependencies from command line:

       java -jar myProject.jar
