Working with ReportGenerator in Cake

[garywoodfine]

I am having issues with ReportGenerator in a Cake Build Script and I'm not sure I have configured it correctly

I am running the Cake Script on a Linux Machine

const string TEST_COVERAGE_OUTPUT_DIR = "coverage";
Task("Test")
    .IsDependentOn("Build")
    .Does(() => {
       
       var testSettings = new DotNetTestSettings  {
                             Configuration = configuration,
                             NoBuild = true,
                    };
                    
     var projects = GetFiles("./test/**/*.csproj");
     foreach(var project in projects )
     {
     
      var coverageOutput = Directory(TEST_COVERAGE_OUTPUT_DIR);
      var codeCoverageOutputName = $"{project.GetFilenameWithoutExtension()}.cobertura.xml";
      var coverletSettings = new CoverletSettings {
                                CollectCoverage = true,
                                CoverletOutputFormat = CoverletOutputFormat.cobertura,
                                CoverletOutputDirectory =  coverageOutput,
                                CoverletOutputName =codeCoverageOutputName,
                                 ArgumentCustomization = args => args.Append($"--logger trx")
                            };
      
       Information($"Running Tests : { project.ToString()}");
       DotNetTest(project.ToString(), testSettings, coverletSettings );
      
     }
});

Task("GenerateReport")
    .IsDependentOn("Test")
    .Does(() =>
{
   var directory = Directory(TEST_COVERAGE_OUTPUT_DIR);
    Information($"Directory Path : { directory.ToString()}");
     
    var glob = new GlobPattern($"./{ directory}/*.cobertura.xml");
    
    
     Information($"globpattern : { glob.ToString()}");
     var outputDirectory = Directory("./reports");

    var reportSettings = new ReportGeneratorSettings
    {
        ArgumentCustomization = args => args.Append($"-reportTypes:HtmlInline_AzurePipelines")
    };
    
     ReportGenerator(glob, outputDirectory, reportSettings);
 
});

When I execute script , the cobertura files are generated However, when attempting to generate the reports I get

n error occurred when executing task 'GenerateReport'.
Error: An error occurred trying to start process ..... with working directory .... Exec format error

When I installed the Report Generator locally and exexuted

 ~/tools/reportgenerator -reports:*-coverage.cobertura.xml  -targetdir:report

It generates the report as expected but it doesn't in the Cake Script

Is there some addtional configuration I need to do in the Cake Script ?
I came across this question on Stack overflow https://stackoverflow.com/questions/62705105/reportgenerator-is-not-recognized-as-an-internal-or-external-command-operable

Which seemed to indicate I needed to register the tool locally. I assumed Cake took care of that?

I think I managed to resolve the issue myself

I found this https://www.nuget.org/packages/dotnet-reportgenerator-globaltool

I then added the following import to my cake script

#tool dotnet:?package=dotnet-reportgenerator-globaltool&version=5.1.19

I then ran the script and it all worked!
