Here is java version and error message when testing the scanner from server:
[root@devbagent061 share]# java --version

java.lang.UnsupportedClassVersionError: org/sonarsource/scanner/cli/Main has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

Not sure what steps to take next? Any help appreciated. Thanks!

Hi,

The server supports analyzing with Java 11. Unfortunately, we’ve released new scanner versions since 9.9 was released and bumped up the required version there. You can use the Show more link on the SonarScanner page to access the download for SonarScanner 4.8 if you really need to.

Or if this is a question of needing to build to a lower Java version, you can do that with Java 17, and the -target compile option.

 
HTH,
Ann
