问题描述
我正在尝试生成测试覆盖率报告，并在我的项目构建完成后查看关于Teamcity的信息。到目前为止，我已经能够使其在我的本地计算机（Windows）上运行而没有任何问题。该报告正在生成，我能够查看覆盖率报告（生成的html文件），但是在teamcity（使用linux agent构建项目）上失败，并显示以下错误：

我也尝试使用dotnet-reportgenerator-globaltool，遇到相同的错误。 我还为ReportGenerator和dotnet-reportgenerator-globaltool指定了要使用.dll而不是.exe来运行ReportGenerator的ToolPath，仍然没有运气。
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);
});
在Teamcity上运行ReportGenerator时，我缺少什么吗？请告知。
解决方法
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
然后两次调用Cake，首先引导模块：
dotnet cake --bootstrap --verbosity=verbose && dotnet cake --verbosity=verbose
