I want to check my Ruby on Rails app with sonarqube. I've added the Web plugin which should work with Ruby but I get the following error during sonarqube exectution:

Once SonarQube is upgraded to 7.4, ruby analysis was available by default. No configuration was required on the Admin side/web app. We did the following to do an analysis of our ruby project.
SonarScanner is a separate client type application that in connection with the SonarQube server will run project analysis and then send the results to the SonarQube server to process it. SonarScanner can handle most programming languages supported by SonarQube except C# and VB.
Overview. SonarQube includes support for the programming languages Java (including Android), C#, C, C++, JavaScript, TypeScript, Python, Go, Swift, COBOL, Apex, PHP, Kotlin, Ruby, Scala, HTML, CSS, ABAP, Flex, Objective-C, PL/I, PL/SQL, RPG, T-SQL, VB.NET, VB6, and XML.
SonarQube has dropped support for Ruby.
If you want to supply code styles check for your application, you take a look into following links:
Ruby Style Guide.
RuboCop - Ruby static code analyzer. Out of the box it will enforce many of the guidelines outlined in the community rails-style-guide. Very configurable and well maintained gem.
Guard-ruboCop - allows you to automatically check Ruby code style with RuboCop when files are modified.
Rails best practices - a code metric tool to check the quality of rails cod. Well maintained.
Simplecov - code coverage analysis tool for Ruby (tests).
Reek - is a tool that examines Ruby classes, modules and methods and reports any Code Smells it finds.

Looks like SonarQube 7.4 now has support for Ruby!
