Scanner ignores Javascript files in C# project

Hi, I’m using dotnet sonarscanner to analyse a repository which contains multiple projects.
At least one project has both C# and Javascript code. Only the C# code is being picked up by sonarscanner.
This is despite all of the code being referenced in the .csproj.

Could you please help me get the javascript code analysed on top of the C# code?

  • ALM used: GitHub

  • CI system used : GitHub Actions

  • Scanner command used when applicable:
    dotnet sonarscanner begin /k:"REDACTED" /d:sonar.host.url=https://sonarcloud.io /d:sonar.login="REDACTED" /o:"REDACTED"
    .\Build.cmd
    dotnet sonarscanner end /d:sonar.login="REDACTED"

  • Languages of the repository: C# and Javascript

  • Error observed (wrap logs/code around with triple quotes ``` for proper formatting)

.csproj of project includes javascript files:
<Content Include="Scripts\dist\app.all.js" />

Output of dotnet sonarscanner end:

The code page on SonarCloud shows the Scripts folder is missing

Hi @Vincent-FundApps

Yes this is a know aspect of the Scanner for MSBuild : it can only analyse the dotnet code.

On way to achieve what to want is to do a second analysis for your JS code only. Be careful though : you will have to create another SonarCloud project for that, otherwise the latter analysis will overwrite everything.

HTH,

Thanks @mickaelcaro. I wish I had come to you earlier.

It’s probably worth mentioning this in the sonarscanner MSBuild documentation: https://docs.sonarqube.org/latest/analysis/scan/sonarscanner-for-msbuild/

Hi @Vincent-FundApps. We’ve had a discussion internally about the expected behaviour and we’d like to revise our previous answer.

The SonarScanner for MSBuild can analyse non-C#/VB files if those files are referenced in the MSBuild project. More specifically, any files using one of the ItemTypes in this list should be analysed automatically. If the ItemType you are using isn’t in the list, you can add it as described here.

Now, as to why your .js files are not being analysed:

Content is included in the list of ItemTypes that should be analysed. However, Scripts\dist\app.all.js doesn’t include any of the wildcards that are used by MSBuild, so it refers to a single file.
As an example, an expression like Scripts\dist\*.js would include all .js files in the dist folder.
An expression like Scripts\**\*.js would include all .js files in all folders under Scripts.

You can check which files the scanner thinks should be analysed by looking in the file .sonarqube\out\sonar-project.properties after MSBuild has finished.

FYI we’ve created a ticket to update the scanner documentation: https://jira.sonarsource.com/browse/SC-2048.

Apologies for any inconvenience caused.
