Hi @maksat-software ,

thanks for this!
Currently this is introducing a lot of whitespace changes. Could you minimize these?

Also it seems to me, this PR breaks compat with SQ 6.7.
sonar-stash tries to preserve compatibility with the latest LTS version of SQ, which currently is 6.7.
Do you think it would be possible to support both 6.7 and 7.6 at the same time?

Also, the release file should not be part of the source repository.

@maksat-software I created a new PR #199 that

• Implements support for 7.6, without dropping 6.7
• Adds a new integrationtest to make validate multi-module projects

If you want, you can test it.
I will update the dependencies separately.
