Version 9.6.1 (build 59531)
And before you ask, no, I’m not able to update.
But this problem is related to the build-wrapper, I’m not getting to the analysis yet.
Bet yes, I know, the wrapper comes with the Sonar version ;).
Could you share with us the file build-wrapper.log? It should be next to build-wrapper-dump.json.
If you prefer not to make it public, I can send you a message so you can share it privately.
Make sure you upgrade to SonarQube v9.9 LTS soon, not only to benefit from our Best LTS Ever™, but because soon we will systematically ask users to upgrade when they ask questions about earlier versions of SonarQube, which are now considered unsupported.
Seriously, it’s an unsupported release that will receive no bug fixes or security updates.
