I'm trying to generate test coverage report and view on teamcity after my project build is complete. So far I have been able to make it work on my local machine (windows) without any issue. The report is generating and I am able to view the coverage reports (html files generated) but it is failing on teamcity (project building with linux agent) with the error below:
Error: System.AggregateException: One or more errors occurred. (Exec format error)

I tried with dotnet-reportgenerator-globaltool as well, encountered same error. I also specified the ToolPath for ReportGenerator to run using the .dll instead of .exe for both ReportGenerator and dotnet-reportgenerator-globaltool, still no luck.
Please find part of my cake script below:
#tool nuget:?package=ReportGenerator
#addin nuget:?package=Cake.Coverlet
// define variables
...
Task("Test")
.Does(() =>
{
var resultsFolder = Directory(@".\coverage\");
if (testProjectFiles != null)
{
var settings = new DotNetCoreTestSettings
{
Configuration = "Release"
};
foreach (var projectFile in testProjectFiles)
{
var coverletSettings = new CoverletSettings {
CollectCoverage = true,
CoverletOutputFormat = CoverletOutputFormat.opencover,
CoverletOutputDirectory = resultsFolder,
CoverletOutputName = $"{projectFile.GetFilenameWithoutExtension()}.opencover.xml",
};
Information("Running tests in {0}", projectFile.GetFilenameWithoutExtension());
DotNetCoreTest(projectFile.ToString(), settings, coverletSettings);
}
}
else
{
Warning("No unit tests found in the solution!");
}
});
Task("GenerateCoverageReport")
.Does(() =>
{
// Generate test coverage report
var reportGeneratorSetting = new ReportGeneratorSettings{
Verbosity = ReportGeneratorVerbosity.Verbose
};
// ---> failing on teamcity
ReportGenerator("./coverage/*.xml", "./coverage", reportGeneratorSetting);
});
Is there anything I'm missing for the ReportGenerator to run on teamcity? Please advise.
Try using the dotnet tool package instead:
Then invoke Cake twice, first to bootstrap the module:
