Answer 1

You can run a jar file using the exec:java goal by adding some arguments:

    org.codehaus.mojo
    exec-maven-plugin
    1.3.2
    
        org.example.Main
        
            -jar
            target/myJar-1.0-SNAPSHOT.jar
        
    

If you have an executable jar and don't want to define the entry point, you need to set the executable and use the exec:exec goal:

    org.codehaus.mojo
    exec-maven-plugin
    1.3.2
    
        java
        
            -jar
            target/myJar-1.0-SNAPSHOT.jar
