Not working with the latest SonarQube versions

[leonardomerlin]

Issue and Steps to Reproduce

If you try to run with the latest version (ie 9.1), then you will face the following error:

java.lang.UnsupportedClassVersionError: org/sonar/batch/bootstrapper/EnvironmentInformation has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Proposed solution

The issue seems to be with the Java version from the docker image used. Class file version 52 is for Java 8. And Class file version 55 needs Java 11.

Drop the unofficial docker image and use to official one: https://hub.docker.com/r/sonarsource/sonar-scanner-cli
