Could not find any coverage report file matching the pattern

I believe your analysis parameters for the reportPaths is looking for *.trx and *.coveragexml files within the $(Agent.TempDirectory) as shown here:

sonar.cs.vstest.reportsPaths=D:\a\_temp\**\*.trx
sonar.cs.vscoveragexml.reportsPaths=D:\a\_temp\**\*.coveragexml

But in Task “9 Run unit tests and Publish report on pipeline”, the *.trx file is in a different directory:

2021-07-08T10:43:16.9579233Z Results File: D:\a\1\s\TestResults\VssAdministrator_WIN-OPGFMDA7R6A_2021-07-08_10_43_15.trx

In Task “11 Run code coverage”, you generated a coverage.cobertura.xml file, which is not an accepted format for SonarCloud and C# coverage:

2021-07-08T10:45:04.7381845Z   Generating report 'D:\a\_temp\TestResults\coverage.cobertura.xml'

So in summary:

Please double-check the directory of the *.trx file, it’s $(Agent.TempDirectory)\**\*.trx is not the right report path.
Please double-check the file type and the coverage task. From Task Coverage and Execution, we only accept these formats:

C#

sonar.cs.vscoveragexml.reportsPaths

Path to the Visual Studio Code Coverage report. Multiple paths may be comma-delimited or included via wildcards. See Notes on importing .NET reports below.

sonar.cs.dotcover.reportsPaths

Path to dotCover coverage report. See Notes on importing .NET reports below.

sonar.cs.opencover.reportsPaths

Path to OpenCover coverage report. See Notes on importing .NET reports below.

This post might help if you are wanting to use coverage.cobertura.xml, which uses sonar.coverageReportPaths with the generic test data format
