Eclipse runs old code

eclipse runs old code.
I cleaned the project and build it again but eclipse show me always the old code.
I my editor window i see the new code, but in the debug there is old code.
This is my Window --> Preferences --> Run/ Debug --> Launing Window:

I installed eclipse from the officile eclipse/smarthome site and selected openHAB 2, OpenHAB 2 Bindings, eclipse smarhome and ESH Core (Does not know the exactly name of this repo) to clone from github.

When i open the files with the editor it shows me the new code.

Somebody can help me?

This is my window.

I changed code in Runtime Folder and there in
org.eclipse.smarthome.io.rest.core.internal.item.ItemResource.java

I created an issue in eclipse/smarthome repo…
