Symlinks cause sonar analysis to fail when using Concourse with Windows worker

[jstaley]

Description

Running Sonar scanner via Concourse fails with path issues

Repro steps

Create pipeline using Concourse. Run the analysis on Windows with Concourse. Scanner fails to find files due to symlink issue. Concourse symlinks the source repository to containers/live. This causes the analysis to fail with referenced file erros

1. Step A

2. Step B

If possible then please create a git repository with a repro sample or attach a zip to the issue.

Expected behavior

The analysis path to the file is the same as the sonar output

Actual behavior

File paths do not match.

This seems to be a general problem with SonarScanner for MSBuild 4.3.1. I am running this via TeamCity on an agent that has the work directory set to a relative path of the agent installation. Agent is installed on a symlink to another drive (eg. c:\buildagent is a symlink to e:\apps\buildagent).

When it runs with this setup, the builds and testing are done on the symlink drive but the end results are written to the actual drive, which results in all of the protobuf files not being read by the scanner.

I 'fixed' this by changing the work directory on the agent to be the absolute path to the actual location instead of using the symlink. Ideally the scanner should be able to handle symlinks properly.

Same issue. Guys any updates?

Hi @jakubprusak,
Sorry we haven't been able to work on this topic yet. We will keep you in touch with updates.

Hi @jstaley, @victrola0000 and @jakubprusak,

Has one of you been able to test newer versions of the scanner for msbuild? If so are you still experiencing the issue?

[victrola0000]

@Evangelink The last time I checked it was still happening.
Using sonarscanner msbuild 4.4.2.1543

Hi @victrola0000,

Thanks! We will have a look this week.

I'm getting similar warnings with the Azure DevOps integration with SonarCloud. Is there a workaround?
