Describe the bug
The latest version (3.0.0) of this plugin appears to require Java 11.
However as it's claimed to support Sonar 8.9+ where Java 8 is still supported for the scanners: https://docs.sonarqube.org/8.9/requirements/requirements/#header-3 this requirement seems incorrect.
Our Maven projects that use Java 8 and this plugin are now getting an error about the plugin being compiled for Java 11.
We had to revert to the plugin 2.0.8 for now.

Current behavior
Maven output:
[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.9.1.2184:sonar (default-cli) on project xyz: The plugin [dependencycheck] does not support Java 1.8.0_322: org/sonar/dependencycheck/DependencyCheckPlugin 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
