                            <transformers>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                    <mainClass>net.javatutorial.tutorials.services.FileUploadService</mainClass>
                                </transformer>
                            </transformers>
                        </configuration>

                </executions>
            </plugin>

Answer 1

If you want an executable jar, your Jersey app needs to be a standalone app, which is an app that runs from a "main" class with a main method. To easily create a standalone app, you can use the Maven archetype mentioned in the Jersey Getting Started . (You can see the generated files from the archetype in this post ).

mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-grizzly2 \
-DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
-DgroupId=com.example -DartifactId=simple-service -Dpackage=com.example \
-DarchetypeVersion=2.27

Once you have your standalone app, then you can build it with the maven-shade-plugin like you are currently doing. The Main class is what you should specify in the <mainClass> element. One thing I should mention is that you should also use the ServicesResourceTransformer to concatenate the services files ¹
