Msbuild不支持多线程解决方案构建 [英] Msbuild not supporting multi thread solution build

问题描述

我有一种情况是在多线程中使用MSBUILD构建多个解决方案，但在构建期间，总是很少有解决方案失败。我尝试逐个构建每个解决方案，它的工作完美。但我尝试使用多线程构建5解决方案，很少生成失败。当我调查成功构建和失败构建的构建日志文件时，似乎MSBUILD与每个构建过程发生冲突。作为参考，我附上了两个构建日志的文本文件。



提交ID 11468的构建开始



构建开始提交ID 11468

字符串SolutionPath = System.IO.Directory.GetFiles（SolutionFolder，* .sln）。 FirstOrDefault（）; 
 WriteLog（A，TimeStartExecute.ElapsedMilliseconds.ToString（），string.Format（构建解决方案名称{0}，SolutionPath））; 
 ProjectCollection pc = new ProjectCollection（）; 
 Dictionary GlobalProperty = new Dictionary（）; 
 GlobalProperty.Add（配置，appConfiguration）; 
 GlobalProperty.Add（平台，appPlatform）; 
 //GlobalProperty.Add(\"Platform，x86）; 
 GlobalProperty.Add（OutputPath，appOutputPath）; 
 GlobalProperty.Add（VisualStudioVersion，appVSVersion）; 
 GlobalProperty.Add（BuildInParallel，true）; 
 GlobalProperty.Add（maxcpucount，2）; 
 BuildParameters bp = new BuildParameters（pc）; 
 
 
 if（appBuildLogger.Equals（true））
 {
 bp.Loggers = new [] 
 {
 new FileLogger 
 {
 Verbosity = LoggerVerbosity.Detailed，
 ShowSummary = true，
 SkipProjectStartedText = true，
参数= @Logfile =+ SolutionFolder +\\ build .log
} 
}; 
} 
使用（BuildManager objBuildManager = new BuildManager（））
 {
 BuildRequestData BuildRequest = new BuildRequestData（SolutionPath，GlobalProperty，14.0，new string [] 
 {Build}，null，
 BuildRequestDataFlags.ReplaceExistingProjectInstance）; 
 BuildResult buildResult = objBuildManager.Build（bp，BuildRequest）
 if（buildResult.OverallResult == BuildResultCode.Success）
 {
 buildPath = Convert.ToString（buildResult.ResultsByTarget.FirstOrDefault （x => 
 x.Key ==Build）。Value.Items [0]）; 
} 
} 

我的尝试：



调查后通过构建日志发现构建过程中的问题..

故障构建日志 https://github.com /Microsoft/msbuild/files/1115979/11468.failed.txt

解决方案

在failed.txt中我可以看到MsBuild在找到时遇到问题CopyArray_Test 并在很多地方进行搜索，直到找到一个你可能不想要的地方。

所以请确保你的路径正确，也许做重建也会有所帮助。 / BLOCKQUOTE>

I have a situation to build multiple solution using MSBUILD in multi threading, but during build, always few solution get failed. I have try to build each solution one by one , its working perfectly. but i have try to build 5 solution using multi threading, few build get failed. As I investigated the build log file of both success build and failure build, it seems MSBUILD getting conflict with each build process. For reference I have attached two text file of build log.

string SolutionPath = System.IO.Directory.GetFiles(SolutionFolder, "*.sln").FirstOrDefault();
                WriteLog("A", TimeStartExecute.ElapsedMilliseconds.ToString(), string.Format("Build solution name {0}", SolutionPath));
                ProjectCollection pc = new ProjectCollection();
                Dictionary GlobalProperty = new Dictionary();
                GlobalProperty.Add("Configuration", appConfiguration);
                GlobalProperty.Add("Platform", appPlatform);
                //GlobalProperty.Add("Platform", "x86");
                GlobalProperty.Add("OutputPath", appOutputPath);
                GlobalProperty.Add("VisualStudioVersion", appVSVersion);
                GlobalProperty.Add("BuildInParallel", "true");
                GlobalProperty.Add("maxcpucount", "2");
                BuildParameters bp = new BuildParameters(pc);
                 

                if (appBuildLogger.Equals("true"))
                {
                    bp.Loggers = new[]
                    {
                        new FileLogger
                        {
                        Verbosity = LoggerVerbosity.Detailed,
                        ShowSummary = true,
                        SkipProjectStartedText = true,
                        Parameters=@"Logfile="+SolutionFolder+"\\build.log"
                        }
                    };
                }
 using (BuildManager objBuildManager = new BuildManager())
 {
 BuildRequestData BuildRequest = new BuildRequestData(SolutionPath, GlobalProperty, "14.0", new string[]
 { "Build" }, null,
    BuildRequestDataFlags.ReplaceExistingProjectInstance);
    BuildResult buildResult = objBuildManager.Build(bp, BuildRequest)
 if (buildResult.OverallResult == BuildResultCode.Success)
 {
  buildPath = Convert.ToString(buildResult.ResultsByTarget.FirstOrDefault(x =>
x.Key == "Build").Value.Items[0]);
 }
}

What I have tried:

After investigation found the problem in build process by build log..

Success build log https://github.com/Microsoft/msbuild/files/1115978/11468.success.txt

failure build log https://github.com/Microsoft/msbuild/files/1115979/11468.failed.txt

解决方案

In failed.txt I can see that MsBuild has problems finding CopyArray_Test and searches in lot of places until it finds one that you probably did not intend.
So make sure you have got your paths right, and maybe doing a Rebuild will help too.
