Thanks for this plugin at all and this PR.

Would it be possible to consider renaming this PR to something like 'Fix Build with Docker' to make its purpose even clearer? It helps other to find it while it is not being merged.

Adding the whole error message to make it easier to find when searching for it:

tl;dr: git ... No such file or directory

Additionally, we would be grateful if this PR could be prioritized for merging, as the current Docker build process as documented in the README is unfortunately broken and requires these changes to function correctly again.

Thank you very much for your attention to this!
