How to run ESH from Eclipse IDE with changes?

I have ESH project from http://docs.openhab.org/developers/development/ide.html tutorial.
Now when I make changes to it and run it those changes dont show up.
Instead Eclipse runs jars from
"openhab2-master\ws.metadata.plugins\org.eclipse.pde.core.bundle_pool\plugins".
Am I missing something?

In “Debug Configuration” -> Plugins, you can find two sections, Workplace and Targetplatform. You might have to deselect the plugin/binding you are changing in section Targetplatform and select it in section Workplace.

Thank you. That solved my problem.
