Error running OpenKNXproducer on v5.1.5

[sgeb]

Steps to reproduce

1. Installed latest OpenKNXproducer v3.12.2 with .\Install-OpenKNX-Tools.ps1

2. Cloned and prepared dependencies (tag v5.1.5 == f13098e)

   git clone https://github.com/OpenKNX/OAM-RaumController
   cd OAM-RaumController
   git checkout v5.1.5
   cd restore
   .\Restore-Dependencies.ps1
   

   Two smaller issues related to this:

   1. The command .\Restore-Dependencies.ps1 contains the following error to checkout bd01c36 on OGM-Common:

      - CloneRepository - Cloned  OGM-Common : 'https://github.com/OpenKNX/OGM-Common' to '[...path...]\dev\OGM-Common'  √
      error: pathspec 'bd01c36' did not match any file(s) known to git
      - CloneRepository - 'OGM-Common' Hash 'bd01c36' Checked out. √
      

      Neither commit bd01c36 nor branch new/improve-build-debug-environment exist in project OGM-Common. This is fixed by pinning to 193e462 in dependencies.txt, which is the release commit for v1.5.1:

        06ebdcb v1 lib/OFM-VirtualButton https://github.com/OpenKNX/OFM-VirtualButton.git
      - bd01c36 new/improve-build-debug-environment lib/OGM-Common https://github.com/OpenKNX/OGM-Common
      + 193e462 v1 lib/OGM-Common https://github.com/OpenKNX/OGM-Common
        d4f8a07 v1 lib/OGM-HardwareConfig https://github.com/OpenKNX/OGM-HardwareConfig

   2. The command .\Restore-Dependencies.ps1 fails to pin the commit but the overall command doesn't fail. Better would be to fail the entire command. This led me to overlook the error multiple times.

3. Run task OpenKNXproducer OAM-RaumController in VSCode.

Other information

Tried with ETS v6.0.6, v6.2.0 and v6.3.1 -- same results.
Tried with OpenKNXproducer in different recent versions -- same results.

=> Is there an additional step needed to produce the knxprod file? Thanks!
