Configure Eclipse to launch a fixed project in a workspace?

I have a small workspace with 3 projects. One main (Swing) application, two other projects tha开发者_StackOverflow社区t are just libraries.

Now, whenever I change stuff in my library project and want to execute i.e. run with Ctrl+F11) or debug , I have to select my main project first and run that.

Is there any way to set this up more smoothly, so I can just run my program regardless of which of my 3 project that is selected ?

Have a look at the "Launching" preference page. At the botton you can select *Always launch the previously launched application. That should do the trick...

If you are using Maven you can create hierarchical structure of projects, i.e. head and child projects. In this case try to define Run/Debug profile on the parent's project level. Probably it will work from any other child project.

I personally have never try this and unfortunately cannot try this right now but I hope it will work for you.

If it does not work it seem you have to create your own eclipse plugin.

Good luck.
