[Solved]-Running multiple launch configurations at once-eclipse

You don't need any plugin:

1. Create all Run Configurations in eclipse
2. Select Organize Favorites...
3. Add you favorites, done

You can create a separate class that calls your program with different arguments, and run it instead.

public class YourClass {
    public static void main(String arg){
        System.out.println(arg);
    }
}

public class YourClassTester {
    public static void main(String[] args){
        YourClass.main("SomeArg1");
        YourClass.main("SomeArg2");
        YourClass.main("SomeArg3");
    }
}

There are two more options listed in Launch an Eclipse Run Configuration from ANT.

You could group them in Ant and then call them using Ant4Eclipse. Or call multiple launch configs from a command script using eclipse remote control.

Since Eclipse Oxygen (4.7.0) you can use a run configuration of the type Launch Group for that.

This short video shows how to use a Launch Group.

EDIT: According to this answer since Eclipse Oxygen (4.7.0) you can use a run configuration of the type Launch Group for that.

Just install "C/C++ Development Tools" from the CDT (see eclipse.org/cdt/downloads.php ) - this single package is enough, no other CDT packages are needed. This won't disturb your Java environment ;-) Then you have "Launch Groups", for any kind of project, including Java projects. See the following screenshot:

You can run or debug the projects (also mixed mode), define delay times and so on. Have fun!
