Hi @Ravikumar2 ,

The error message indicates that you need to run the SonarQube scanner with a JRE 8 version that is compatible with SonarServer 10.6.

It is important to understand that the JRE version used by the scanner is independent of the Java version of the code being analyzed.

In other words, even if your application uses Java 8, the SonarQube scanner must use a JRE 17 which is compatible with SonarServer.

Here are the steps to solve this problem:

  1. Check the JRE version used by your SonarQube scanner. You can usually find this information in the scanner configuration or in the log files.
  2. Make sure that the JRE version used by your scanner is compatible with SonarServer 10.6 . You can find information about compatible JRE versions in the official SonarQube documentation. SonarScanner requirements | SonarQube Server Documentation
  3. Reconfigure your SonarQube scanner to use the new JRE version.

Once you have updated your JRE and reconfigured the scanner, you should be able to run the code analysis without encountering the error.
