Duplicate ProjectGuid Warning with Sonar MSbuild runner.

[Lexus-3141]

Hi. I have thouble with runner hook.
Plugin catch teamcity temporary file *.csproj.teamcity
[Step 12/12] WARNING: Duplicate ProjectGuid: "f8cc0961-f946-467c-a3d0-2251ab2852dc". The project will not be analyzed by SonarQube. Project file: "C:\TeamCity\buildAgent\work\a768aae0f58b116\repo\testconsole\TestConsole.csproj.teamcity" [14:07:11][Step 12/12] WARNING: Duplicate ProjectGuid: "f8cc0961-f946-467c-a3d0-2251ab2852dc".

What's wrong? How can do I avoid this?

Teamcity ver: Professional 2018.2.3 (build 61544)
SonarQube plugin ver: P2017.1-22

Please check this ticket on SonarSource bugtracker - there's an explanation of this message

Unfortunately, it's miss. I'm understand abount GUIDs in sln. But we have deferent trouble here.
'TestConsole.csproj.teamcity' - not a project's file. I mean it's temporary teamcity engine file. I've checked it exists short time only and plugin catchs it as real project file.

Then you should filter out this path. There's sonar.exclusions parameter which can be added to the runner but as far as I see (eg here) it's not working with Scanner for MSBuild. There's one workaround mentioned in that post. Unfortunately I'm not in common with .Net and cannot check it myself but will try to find more information.

[Lexus-3141]

Hmm, may will you filter it out programmaticaly? Because i mean it's wrong plugin behavior. It reacts to teamcity service file.

[Linfar]

What do you mean by teamcity service file? Does everything work when running the same procedure is run from commandline?

[Lexus-3141]

I guess *.csproj.teamcity files creates by teamcity wrapper for short time and it is outside the users scope. The file has a correlated to real project name. In my case the bug happens for one small project only. Can do we investigate this? But I know about the files nothing.

[Linfar]

I will ask my colleges who are responsible for .Net support in TeamCity about these files. If possible I will add some filtering by default.

Meanwhile you can try to add some manual exclusion to check workaround.

Upd:
I've fixed this used teamcity build configutation parameter teamcity.msbuild.generateWrappingScript=false
It's mentioned here: https://stackoverflow.com/questions/4211683/why-does-teamcity-add-csproj-teamcity-patch-to-web-app-package-files

But have one more trouble.
Windows has case-insensitive file paths, but the plugin is case-sensitive if define lowercase confiruration param for MSBuild step and repo has case-different file path.

It's one and the same file indeed.

[Linfar]

Which parameter caused this?

[Lexus-3141]

We have the template containing msbuild runner step. Step parameter "Build file path:" is defined as a %configuration parameter% for users.

[Linfar]

This seems to be 2 bugs - one in TC MSBuild Runner generating somewhere a project reference in different casing and SonarQube MSBuild Scanner bug not filtering same paths on Windows. I need some time to investigate this.
