java - How can I create independent TestNG Maven executable

Question

I need to create a .jar file using maven and testng. My jar needs to read a testng.xml file and execute all the tests that are in there. I tried maven-shade-plugin and created a jar, but when i try to execute it i have the error:Could not find or load main class org.testng.TestNG. I tried to solve this problem finding a lot of solutions suggesting to create classpath but i fear this is not what i need. My jar file will be uploaded in a server and it will have to be executed from there, i can't create a classpath on that server, i need an independent file. i can use some workarounds if thery are able to do this task (war file, exe file, etc...)

My tests are under the src/test/java path. My POM:

        <repository>
            <id>jcenter</id>

        </repository>
    </repositories>

                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

I had a similar requirement long time back. You would need to create a jar with all dependencies. I had written up the process I followed here. HTH.
