Code isn't analyzed using Azure DevOps Unity 3D pipeline

Dear community,

in general, the idea is to build a project developed in Unity 3D via a pipeline so that we can analyze its code with SonarCloud.
The build of a Unity 3D application is first done via Unity itself, which creates a Visual Studio .sln. This in turn is used to create an App Package from the project.

To map this in Azure DevOps, we use the following extensions:

To build the pipeline, we used the following documentation:

The pipeline runs through successfully. SonarCloud also seems to work somehow. The problem, however, is that SonarCloud doesn’t seem to analyze any code. See screenshot:

Our pipeline.yaml file:

# This build pipeline is designed for ARM UWP projects, running Unity 2019.x or later, with MRTK Foundation 
# If using 2018.x or earlier: Change unity.installComponents to 'Windows, UWP_IL2CPP'
# If not using MRTK Foundation: Change unity.executeMethod to your build method (We recommend basing off the one in MRTK Foundation)
# If you want to build x86 UWP builds: In theory should just be able to change vs.appxPlatforms, but it's a TODO
# This pipeline depends on secret variables that you must define within your Azure DevOps!
#   unity.username  = <Your Unity account username / email>
#   unity.password  = <Your Unity account password>
#   unity.serialkey = <The serial key for your Unity pro licence>
# Without all three, this pipeline will fail to run!
# Unity will be licensed, used, and then unlicensed during the unity and unitytests jobs in this pipeline.
# A Pro license works on 2 machines, and in theory this pipeline will only use one licence at a time.
# However, should there be unexpected errors and deactivation doesn't complete properly, you may need to log into your Unity account and deactivate all.
# Variables predefined for this build process:
  # If true, will run tests, otherwise skip them. If you do not have tests, set to false to increase build speed.
  runTests: false
  # The path to the folder which contains the Assets folder of the project.
  # If your Unity project is located in a subfolder of your repo, make sure it is reflected in this.
  unity.projectPath:        '$(System.DefaultWorkingDirectory)/'
  # If you are using Unity 2019 or later, leave this alone!
  unity.installComponents:  'Windows, UWP'
  # If you are using Unity 2018 or earlier, comment out the above and uncomment below:
  #  unity.installComponents:  'Windows, UWP_IL2CPP'
  # Explanation: In Unity 2019 and later, .NET scripting was removed. You no longer need to specify 'UWP_IL2CPP', it's now simply 'UWP'!
  # The build method of the Unity project. This assumes you have MRTK in your project, and uses its build script.
  # If you want to customize your build script, change the method name here:
  unity.executeMethod:      'Microsoft.MixedReality.Toolkit.Build.Editor.UnityPlayerBuildTools.StartCommandLineBuild'
  # Are we buolding an .appx for x86 or ARM?
  # TODO: Theoretically, could expect to use 'x86|ARM' to build for both HL1 and 2, but yet to get that to work.
  vs.appxPlatforms:         'ARM'
  # I would not expect you to have to change the rest of these unless you had a special reason:
  unity.targetBuild:        'WindowsStoreApps'
  unity.outputPath:         '/Builds/WSAPlayer'
  unity.editorPath:         '/Editor/Unity.exe'
  vs.packagePath:           '/AppPackages'
  # This also needs to be passed to the install template, along with unity.projectPath
  unity.installFolder:      'C:/Program Files/Unity/Hub/Editor/'

# defaults to 'not provided'
# Path is relative to the file. Defaults to .
# Encoding of the source code. Default is default system encoding

→ The path points to the directory where all C# files are located.

In the logs I could find for example the following WARNING:
WARN: Property missing: ‘sonar.cs.analyzer.projectOutPaths’.

So far we have not been able to find a solution.

We would appreciate if you could help us.

Thank you very much in advance!

Welcome to our Community @paulo_novatec !
Is your project private or public? If public, could you please share the repository and SonarCloud URLs?
I understood that the file is in a parent folder compared to the Assets folder, that is correct? Something like this:

/Assets/* (all source files)

If you have access to the logs, could you check if any file is analysed? You can also share this log with me in a private message, if you think is better!

Hi @Alexandre_Holzhey,
thank you very much for your response!
The project is private which is why I cant share the repo and SonarCloud URL with you.

I understood that the file is in a parent folder compared to the Assets folder, that is correct?

→ Yes that is correct.

I would really like to share the logs with you in a private message. Thank you so much!

Hey @Alexandre_Holzhey,

unfortunately I can’t write you any private messages, although I reached the necessary trust level…
Which is why you can find the logs below:

(logs removed for security)

I only posted the logs from the SonarCloud tasks. Please let me know if other ones would be interesting too :slight_smile:

Thank you very much in advance!


Can you confirm whether you are trying to analyze C# or C/C++ files, or both?

Earlier in the thread you mentioned C#, but there are no C# files referenced in the analysis log, only C/C++.

If you want to analyze C/C++ files then you need to use the CFamily build wrapper.
