Resolution failed. Capabilities satisfying the following requirements could not be found

Development IDE & Build
1

Hi I use Windows 10 and Eclipse Java 2020-09. The error is:

Resolution failed. Capabilities satisfying the following requirements could not be found:
    [<<INITIAL>>]
      ⇒ osgi.identity: (osgi.identity=org.openhab.core)

I installed with Oomph the whole openHAB packages. Also all Core packages. Not only Add-ons and Development. Then I wanted to add a new own binding and the Astro binding to app.bdnrun Run Requirments. After clicking on Resolve the error appears.

Inside git\openhab-addons\bundles I run

mvn clean install -DskipChecks=true -DskipTests=true -Dfeatures.verify.skip=true -Dspotless.check.skip=true -U

without any errors.

I hope you can help. Thanks in advance.
