Want to use sonar-drools-plugin

I m using sonarqube 4.5.1, sonar-drools 0.2
I want to run test my drools project.
I have tried to start the server but failed with error:
java.lang.IllegalStateException: One of HTML description or Markdown description must be defined for rule [repository=sonar-drools-plugin, key=DROOLS_OPTIMISATION]

Hi,

Welcome to the community!

4.5.1 is ancient and far, far past EOL. You should upgrade to either the current LTS, 7.9.3, or the most recent version, 8.3, at your earliest convenience. Note that you’ll have to traverse multiple former-LTSs in the process, so your upgrade path is:

4.5.1 -> 5.6.7 -> 6.7.7 -> 7.9.3 -> 8.3

And unfortunately Drools is no longer supported.
