Hi Jörg-Michael,

I now got a first working version of a Github Action Workflow that uses ABAP Cleaner 😄.
As I am not a GitHub Workflow expert by far, I am not sure if it is the best approach to do it, but hey, it is working.

Here is the workflow in my sample repository. I only had one minor hickup after the job first ran and I tried to import the changes back into my ABAP system.
After a little bit of debugging I found the culprit... crlf 😋. abapGit is splitting the received text content from git at lf into an internal table. The left behind carriage return is then seen as unknown statement and the import fails.

In a local setup the crlf characters written by ABAP cleaner never caused this because of the git setting core.autocrlf = true. And luckily enough this can also be set inside the workflow. So an additional step before the checkout solved it.

    - run: git config --global core.autocrlf true

    - name: Checkout
      uses: actions/checkout@v3

After that additional file changes via the workflow could be imported back to the ABAP system without any issue.

All the best,
Ludwig
