SonarQube: Illegal characters in path

msedi · September 6, 2023, 2:30pm

I’m using SonarQube for code analysis in my azure build pipelines. During my last check-in I get an error message: “Illegal characters in path” without any hint about the location of the problem:

    ##[error]Unhandled Exception:
    ##[error]System.ArgumentException: Illegal characters in path.

    ---

I have already elevated the verbosity to find the problem:

 inputs:
    SonarQube: 'SonarQube'
    scannerMode: 'MSBuild'
    projectKey: 'CT-XXXX'
    extraProperties: |
      sonar.verbose=true
      sonar.log.level=TRACE
      sonar.log.level.app=TRACE
      sonar.log.level.web=TRACE
      sonar.log.level.ce=TRACE
      sonar.log.level.es=TRACE

But didn’t get more information and although I have set it to TRACE it is still:

sonar.verbose=true was specified - setting the log verbosity to 'Debug'

Is there any better switch that prints out the location of the problem?

Hey there.

Thanks for the report.

Can you upload a larger range of logs? It’s difficult to know where the issue is coming from right now.

msedi · September 7, 2023, 7:06pm

Sure. This is what I have

The pipeline looks like this:

The prepare step is this

- task: SonarQubePrepare@5
  inputs:
    SonarQube: 'IPIPE SonarQube'
    scannerMode: 'MSBuild'
    projectKey: 'CT-XXXX'
    extraProperties: |
      sonar.c.file.suffixes=-
      sonar.cpp.file.suffixes=-
      sonar.objc.file.suffixes=-
      sonar.exclusions=**/*.xml,**/*.xaml,**/*.yml,**/*.csproj,**/*.sln,**/*.slnf,**/*.cu,**/*.ptx,**/*.g.cs,**/*.dcm,**/*.png,**/*.ipv,**/*.ipp,**/*.ipx,**/*.IRSTBL,**/*.java,**/*.jar,**/*.html,**/*.css,**/*.js,**/*.py,**/*.cshtml,Tables/,Tools/,tools.p/,pipelines/,documentation/

The Analyze Step is this

steps:
- task: SonarQubeAnalyze@5
- task: SonarQubePublish@5
  inputs:
    pollingTimeoutSec: '300'

which then shows:

and this is all information I have. Maybe there is some switch I can turn on to find at least the path to see whats wrong.

Thanks for your help.

What’s the final one, and would you be able to extract it from the build agent for review?

msedi · September 8, 2023, 6:19am

The last one is 99 although there are in total 331. So they obviously not processed in numerical order. So if this is OK, the last one that is displayed is 99.json


08:07:37.047  The supplied Code Analysis ErrorLog file is a valid json file and does not need to be fixed: F:\agent\_work\2\.sonarqube\out\98\Issues.json
08:07:37.062  The supplied Code Analysis ErrorLog file is a valid json file and does not need to be fixed: F:\agent\_work\2\.sonarqube\out\99\Issues.json

##[error]Unhandled Exception:

If it helps, I have uploaded the whole 99 folder. If you require more information - I’m available
99.zip (2.5 KB)

Additionally I have uploaded the last 331 from the numerical order, because it seems this is also the last created folder (by looking at the folder creation date).
331.zip (99.4 KB)

Colin · September 8, 2023, 7:39am

Thanks. I’m not quite sure where to go from here, so I’ll tag this for some experts.

gregory.paidis · September 14, 2023, 1:59pm

Hey @msedi ,

Share the Scanner for .NET verbose logs

Add /d:"sonar.verbose=true" to the…
- SonarScanner.MSBuild.exe or dotnet sonarscanner begin command to get more detailed logs
  - For example: SonarScanner.MSBuild.exe begin /k:"MyProject" /d:"sonar.verbose=true"
- “SonarQubePrepare” or “SonarCloudPrepare” task’s extraProperties argument if you are using Azure DevOps
  - For example:
```
- task: SonarCloudPrepare@1
    inputs:
      SonarCloud: 'sonarcloud'
      organization: 'foo'
      scannerMode: 'MSBuild'
      projectKey: 'foo_sonar-scanning-someconsoleapp'
      projectName: 'sonar-scanning-someconsoleapp'
      extraProperties: |
        sonar.verbose=true
```
The important logs are in the END step (i.e. SonarQubeAnalyze / SonarCloudAnalyze / “Run Code Analysis”)

Share the msbuild detailed logs

MsBuild.exe /t:Rebuild /v:d

or

dotnet build -v:d

msedi · September 14, 2023, 2:57pm

Thanks for your help.

Attached is the log of our whole build pipeline.

logs_8790.zip (3.6 MB)

I don’t know if this helps. If you need more, please just ask.

Thanks

gregory.paidis · September 18, 2023, 12:07pm

Hey again @msedi ,

Could you run the build part of your dotnet/msbuild step with verbosity set to Detailed and re-send us the logs?

For MSBuild you need: /v:d
For dotnet you need -v:d

For reference, I already opened a ticket on the appropriate a repo, where you can track it.
I am just curious to see which path is the culprit, which might make our verification more accurate when implementing said ticket

Thanks again,
Greg

msedi · September 19, 2023, 6:14am

Hi Gregory,

sorry, that was my fault. While playing around I accidently took the wrong pipeline output.
Attached is the log output with -v:d.

Hi Gregory,

just for you rinformation. It seems the problem was in the excludes.
I was using

sonar.exclusions=...Tables/,Tools/,tools.p/,pipelines/,documentation/

because I wanted to exclude all files unterneath the given folders. When removing the items it worked again.

To make it work I thought the following line works, but it doesn’t

sonar.exclusions=Tables/**,Tools/**,tools.p/**,pipelines/**,documentation/**

What would be the correct way to exclude everything unterneath a folder?

msedi · September 28, 2023, 1:11pm

Hi Gregory,

unfortunately I thought the problem is the wrong path filters. But this was not the case. So I’m struggling now since 22 days with the problem without any solution. Even our main IT department cannot solve it, so it would be nice if we could work on this.

gregory.paidis · October 2, 2023, 2:42pm

Hey @msedi ,

I apologize for the delay.
Unfortunately, after looking into it a bit more, there doesn’t seem to be an easy solution I can implement right now.

I will inform my team and try to prioritize it as much as possible during upcoming work on the scanner side.

Thanks for raising this and sorry again for my slow reply,
Greg

msedi · October 2, 2023, 4:17pm

Gregory, no problem. Is there anything I can do from my side? I think the only problem is that I cannot find out which path causes the problem.

The other side is, even if you can solve something on your side, our company installed SonarQube might not be updated accordingly, so solving the problem on my side would help me most at the moment.

Thanks for your help
Martin

gregory.paidis · October 3, 2023, 12:13pm

Hey again Martin,

Based on your error stack trace, what seems to be the problem is a call to new FileInfo.

As you can see in the constructor exceptions, there is some detection of illegal characters that throws this stack trace.

You could try to find all the files that are processed during the build process from the verbose logs and write a script to check them.

Note: This seems to be happening only in .NET Framework and early .NET Core versions.

Extra note: If you really want to go in depth, you can also check the source code of the method that is throwing inside the runtime.

msedi · October 11, 2023, 6:38am

Hi Gregory,

I have tried to get the log from the server and scanned through all files in config/FilesToAnalyze.txt and any other files in the config and out that contains file pathes, but couldn’t find the error.

I also checked it by using the dotnet sonar-scanner locally and didn’t see any problems there.

Do you have any other idea what could cause the problem. Obviously there is something different on the server.

gregory.paidis · October 11, 2023, 2:56pm

Hey again Martin,

Unfortunately at this time, I am out of ideas.
It will be tackled in the near future when we will work on the scanner.

Thanks and sorry for not being able to help more,
Greg

achtus · September 5, 2024, 8:07am

I see this is an old post. But have you managed to find a workaround or is there a patch? We’re apparently using the latest version 6.3.2 and we’re encountering exactly the same problem in a net8 project without being able to identify ‘the’ file containing illegal characters.

gregory.paidis · September 6, 2024, 4:01pm

Hey Frederic,

Thanks for the reminder.
I have a fix for this, and I will try to add it on the next or second-next release of the scanner for .NET.

achtus · September 9, 2024, 7:05am

As soon as it’s available, I’ll let you know.
