运行 ReportGenerator 在 teamcity 上使用 cake 构建（执行格式错误）

Question

我正在尝试在项目构建完成后生成测试覆盖率报告并在 teamcity 上查看。到目前为止，我已经能够在我的本地机器 (windows) 上毫无问题地运行它。报告正在生成，我可以查看覆盖率报告（生成 html 个文件），但它在 teamcity 上失败（使用 linux 代理构建项目）并出现以下错误：

我也尝试使用 dotnet-reportgenerator-globaltool，遇到同样的错误。我还指定了 ReportGenerator 的工具路径运行使用 .dll 而不是 ReportGenerator 和 dotnet-reportgenerator-globaltool 的 .exe，仍然没有成功。

请在下面找到我的蛋糕脚本的一部分：

#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);
    });

Teamcity 上运行的 ReportGenerator 是否缺少任何内容？请指教

Answer 1

尝试改用 dotnet 工具包：

#module nuget:?package=Cake.DotNetTool.Module&version=0.4.0
#tool dotnet:?package=dotnet-reportgenerator-globaltool&version=4.6.7

然后调用 Cake 两次，首先是 bootstrap 模块：

dotnet cake --bootstrap --verbosity=verbose && dotnet cake --verbosity=verbose

运行 ReportGenerator 在 teamcity 上使用 cake 构建（执行格式错误）

Running ReportGenerator using cake build on teamcity (Exec format error)

teamcity

xunit

reportgenerator

.net-core
