Community SonarQube Error For Swift Language

SonarQube Server / Community Build
1

  • I am using this community Release version 25.8.0.112029

  • SonarQube is deployed via zip

  • I have set up sonarqube on localhost:9000, but when I run the sonar-scanner command on my project folder, it will not show any issues on the sonarqube dashboard. Then I added backelite-sonar-swift-plugin-0.4.6.jar at this position Sonarqube>extensions>plugins. Then I got a compatibility error, and sonarqube server has not been set up. The error has been pasted below.

    How to resolve this. Please help.

Hi,

The Swift plugin is a third-party plugin that doesn’t support recent SonarQube versions, the API it depends on (ProfileImporter) was removed years ago. Version 0.4.6 hasn’t been updated since 2020, so it won’t work with 8.x or newer. The issue was already reported multiple times on the repository without any answer from its mantainer. Do not expect any fix for this.

To get your SonarQube server running again you’ll need to remove backelite-sonar-swift-plugin-0.4.6.jar from extensions/plugins. Community Edition has no built-in Swift analyzer, so without a compatible plugin you won’t see Swift issues.

To analyze Swift, either upgrade to Developer Edition+ for the official Swift plugin, or use a tool like SwiftLint and import its results via SonarQube’s Generic Issue format. Updating the plugin yourself is possible but would require major rewrites to match today’s APIs.
