by the way, sonarqube9 needs java 11 means my project also needs java 11?

Hi,

Welcome to the community!

@roy_zheng

sonarqube9 needs java 11 means my project also needs java 11?

Not at all. You can build your project with (or to) Java 8 and then analyze with Java 11. The docs talk about this.

 
HTH,
