I have a multi-module project

 ![Снимок экрана 2023-09-26 в 18.25.26](https://europe1.discourse-cdn.com/sonarsource/uploads/sonarcommunity/original/3X/7/9/79c315833d6afe06f223fbc6fbf3408f88673eca.jpeg)

I add a SonarQube property to the root gradle

```auto
sonarqube {
    properties {
        property("sonar.sourceEncoding", "UTF-8")
        property("sonar.projectName", "projectName")
        property("sonar.projectKey", "projectKey")
        property("sonar.host.url", "url")
        property("sonar.login", "login")
        property("sonar.language", "kotlin")
        property("sonar.sources", "src/main/")
        property("sonar.tests.exclusions", "src/main/**",)
        property("sonar.tests", "src/main/")
    }
}

```

Use sonarqube ver 4.0.0.2929

But the report contains the results of scanning only xml files

When I configured in Gradle file modules with these properties at the very beginning, all files were scanned. But since I needed to include all the modules in the report, I moved them to the gradle root

How can I get sonar to scan a kotlin file?

Hi,

Version 4.0.0 has a little age on it now. Can you upgrade to the [current version](https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/scanners/sonarscanner-for-gradle/), 4.4.0.3356 and try again?

&nbsp;  
Thx,

Hi  
Honestly, I don’t think this has anything to do with the version, because with ver 3, when defining properties in the gradle module, sonarqube read Kotlin

Okay, but I’m almost immediately out of my depth with Gradle & I can’t escalate for help if you’re not on the latest version.

Hi,

So you’ve upgraded, but are still seeing an error? Can you provide full, debug analysis logs?

The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.

[This guide](https://community.sonarsource.com/t/how-to-find-logs-about-importing-code-coverage/73317) will help you find them.

Hi,  
Yes, that’s right, let me remind you that when I declared sonarqube and its properties in the garadle module, it scanned Kotlin, and when I brought it to root, it stopped transferring

Is this a `--debug` log? Also, could you share your configuration?

Hi,

> [@Kristina](#):
>
> what configuration are you referring to?

It’s been a week and a half. I don’t remember 😂

Based on the log you posted, it seems your analysis command was this?

> `+ gradle sonarqube\`

I.e. you didn’t add the `--debug` specified in the guide I linked earlier?

That means that in 78k lines of logging, there’s no analysis logging, only the mention of the task and about 2k lines about missing JaCoCo reports. There’s nothing to go on here.

Looking back at your OP

> [@Kristina](#):
>
> `property("sonar.language", "kotlin")`

This does nothing. You can drop it.

> [@Kristina](#):
>
> ```auto
> property("sonar.tests.exclusions", "src/main/**",)
> property("sonar.tests", "src/main/")
> 
> ```

I don’t understand the point of this pair. Your test exclusion covers everything you’ve configured for `sonar.tests`.

And per [the docs](https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/scanners/sonarscanner-for-gradle/), `sonar.sources`, `sonar.tests`, `sonar.projectName` and `sonar.projectKey` default to what’s read from your build environment.

I suggest paring this back a bit and trying again **with the `--debug` flag** :

Hi,  
what about sonar.projectName & sonar.projectKey, deleting them too?

there are difficulties with gradle sonarqube --debug, there are a lot of logs, when running on Jenkins the browser crashes when you view them, and locally if you run it shows only the last part, the logs don’t look informative

It seems the problem is still in the gradle declarations, perhaps there is a specialist who can help with this?

We use SonarQube (with it’s Gradle plugin) in a multi module (150+) Android project (with one Android app module and a mix of many Android-library and Kotlin-only modules). We use custom [convention plugins](https://github.com/android/nowinandroid/tree/main/build-logic#convention-plugins) to set up each module properly. In these convention plugins we apply SonarQube plugin per module and set the required properties.  
This is working fine. So you should consider moving to a similar approach.

in this repository are you using sonar? I just can’t find his ad.

and another question, if I make a convention plugin, do I need to specify some sonar properties in gradle root?

Yeah sure. You still need to apply the plugin to the root project and set the `projectKey`, token etc. there. In your submodules you then also apply the plugin but only set your `exclusions`, `reportPaths`, `sonar.tests` path and so on.
