We are currently using SonarQube Server 4.5.7 dowloaded as zip. We are trying to upgrade our java project from Java 9 to Java 11 but we are not planning to upgarde the SonarQube server itself.
So, Is it possible for us to scan java 11 code with older SONAR version?
Sonarqube 4.5.7 is a version of the middle ages past EOL and you shouldn’t use it anymore.
What is preventing you from updating your Sonarqube instance to Sonarqube 9.9.0 LTS/latest ?
