After your changes from https://github.com/oss-review-toolkit/ort/commit/10b38cb65955e18bac471f06ec2c25a1d19e544a we get errors like:

Exception in thread "main" java.io.IOException: Running '/builds/foo/compliance/license-scanning/.ort/tools/ScanCode/30.1.0/scancode-toolkit-30.1.0/scancode --version' in '/builds/foo/compliance/license-scanning/.ort/tools/ScanCode/30.1.0/scancode-toolkit-30.1.0' failed with exit code 127:

We have build your Dockerfile from scratch - docker inline caching or anything else is deactivated.

Thanks for your help.

Could it be that you set a custom entrypoint? ORT now needs to be executed in a login shell to find the installed tools, that's why the default entrypoint is set to: https://github.com/oss-review-toolkit/ort/blob/main/docker/ort-wrapper.sh

@mnonnenmacher: We were using /opt/ort/bin/ort before, which is now at /usr/bin/ort (this is where the ort-wrapper.sh gets copied to). entrypoint is an empty string in our .gitlab-ci.yml file. Thank you for your fast reply. Now it works again.
