after upgrading our custom plugin to 8.9 and deploying it to our SonarQube server I am receiving notifications that SonarLint does not support our plugin. I upgraded SonarLint to 5.9, the notification still appears. In the log file I found the following message:
Starting SonarLint for Eclipse 184.108.40.206414 Starting SonarLint engine for connection 'host'... ... Load plugins ... Plugin 'My Custom Plugin' requires plugin API 220.127.116.11852 while SonarLint supports only up to 8.5. Skip loading it.
SonarQube: 8.9 LTS SonarLint: 18.104.22.168414
