I have a MainThing.launch starting the Simulator with my.package.MainThing as the argument. At first, I thought, I'd just copy and modify the Launch Configuration, but changing the program argument to my.package.TheOtherThing changed nothing. Still, the "MainThing" gets started.
So I thought, I could copy the launch file and change the line
<stringAttribute
key="org.eclipse.jdt.launching.PROGRAM_ARGUMENTS"
value="my.package.MainThing"/>
to contain my.package.TheOtherThing instead, but even after an Eclipse restart, nothing changes.
So what should I do in order to have multiple launches?
