Eclipse插件：将Java进程附加到代码启动

Question

So I am doing an eclipse plugin for educational purposes. My goal now is to have an additional java thread running , when the Run button is hit. So, alongside with the normally launched programme , I want to have my own plugin code running (which I specified in the plugin).

I thought about trying to create a new java thread , running my code when I execute DebugUITools.launch(config, mode); . But I am not sure how I would attach the thread to the launched process so that I could stop the thread too...

I also thought about creating java launch configuration for my plugin code, but it's probably impossible because as far as I can see, we need a Project for that.

So, are there any possibilities to programmatically attach new threads to a launched program? Or maybe create a second launch configuration out of plugin code, and launch it?

I hope I was able to explain my struggle to you.

Answer 1

Each Launch runs the code in a completely new JVM. You can't take a thread in the current JVM and move it to a different one.

A second launch configuration in your code would only end up launching yet another JVM which doesn't get you anywhere.

You would have the modify the existing launch configuration to add a jar containing your code and change the program entry point to point to your code so you can start your thread.
