Hello everyone.  
I installed sonarQube with Helm.  
I encountered some problems in the inspection of the java language. I would like to ask you for advice. The error is shown in the figure. He said very clearly that I need a class file.

I want to add source code checking to my cloud platform. I want the check for all languages ​​to work with

```auto
docker run sonarsource/sonar-scanner-cli .

```

why does the java check still need a class file

Hey there.

The analysis of Java requires the actual bytecode of the compiled application to perform an accurate analysis. That’s why we suggest using the [SonarScanner for Maven](https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/scanners/sonarscanner-for-maven/) or [SonarScanner for Gradle](https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/scanners/sonarscanner-for-gradle/), scanner integrations with the build tools you’re probably already using to build your code.
