Hi,
Welcome to the community!
That’s a really old version of SonarScanner for Maven. The current version is 5.1. You should upgrade, and then add sonar.java.jdkHome to your analysis parameters.
If that doesn’t work, can you provide the full analysis log?
The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.
This guide will help you find them.
Thx,
Ann
