很抱歉,如果我来晚了...但是在问题发布近7年后,我想看到一个完整的答案。我使用下面的代码进行了一些测试,以下是结论:
分析
msbuild.exe
当至少发生一个构建错误时返回 1
,当构建成功完成时返回 0
。目前,该程序不考虑警告,这意味着带有警告的成功构建仍会使 msbuild.exe
返回 0
。
其他错误,例如:尝试构建不存在的项目,或提供不正确的参数(例如/myInvalidArgument
),也会导致 msbuild.exe
返回 1
。
源代码
以下C#代码是通过从命令行启动 msbuild.exe
来构建您最喜欢的项目的完整实现。在编译项目之前,不要忘记设置任何必要的环境设置。
您的 BuildControl 类:
using System;
namespace Example
{
public sealed class BuildControl
{
public bool BuildStuff()
{
MsBuilder builder = new MsBuilder(@"C:\...\project.csproj", "Release", "x86")
{
Target = "Rebuild",
};
bool success = builder.Build(out string buildOutput);
Console.WriteLine(buildOutput);
return success;
}
}
}
MsBuilder类:通过从命令行调用MsBuild.exe来构建项目:
using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
namespace Example
{
public sealed class MsBuilder
{
public string ProjectPath { get; }
public string LogPath { get; set; }
public string Configuration { get; }
public string Platform { get; }
public int MaxCpuCount { get; set; } = 1;
public string Target { get; set; } = "Build";
public string MsBuildPath { get; set; } =
@"C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\MsBuild.exe";
public string BuildOutput { get; private set; }
public MsBuilder(string projectPath, string configuration, string platform)
{
ProjectPath = !string.IsNullOrWhiteSpace(projectPath) ? projectPath : throw new ArgumentNullException(nameof(projectPath));
if (!File.Exists(ProjectPath)) throw new FileNotFoundException(projectPath);
Configuration = !string.IsNullOrWhiteSpace(configuration) ? configuration : throw new ArgumentNullException(nameof(configuration));
Platform = !string.IsNullOrWhiteSpace(platform) ? platform : throw new ArgumentNullException(nameof(platform));
LogPath = Path.Combine(Path.GetDirectoryName(ProjectPath), $"{Path.GetFileName(ProjectPath)}.{Configuration}-{Platform}.msbuild.log");
}
public bool Build(out string buildOutput)
{
List<string> arguments = new List<string>()
{
$"/nologo",
$"\"{ProjectPath}\"",
$"/p:Configuration={Configuration}",
$"/p:Platform={Platform}",
$"/t:{Target}",
$"/maxcpucount:{(MaxCpuCount > 0 ? MaxCpuCount : 1)}",
$"/fileLoggerParameters:LogFile=\"{LogPath}\";Append;Verbosity=diagnostic;Encoding=UTF-8",
};
using (CommandLineProcess cmd = new CommandLineProcess(MsBuildPath, string.Join(" ", arguments)))
{
StringBuilder sb = new StringBuilder();
sb.AppendLine($"Build started: Project: '{ProjectPath}', Configuration: {Configuration}, Platform: {Platform}");
int exitCode = cmd.Run(out string processOutput, out string processError);
sb.AppendLine(processOutput);
if (exitCode == 0)
{
sb.AppendLine("Build completed successfully!");
buildOutput = sb.ToString();
return true;
}
else
{
if (!string.IsNullOrWhiteSpace(processError))
sb.AppendLine($"MSBUILD PROCESS ERROR: {processError}");
sb.AppendLine("Build failed!");
buildOutput = sb.ToString();
return false;
}
}
}
}
}
CommandLineProcess类 - 开始一个命令行进程并等待其完成。所有标准输出/错误都被捕获,不会为该进程启动单独的窗口:
using System;
using System.Diagnostics;
using System.IO;
namespace Example
{
public sealed class CommandLineProcess : IDisposable
{
public string Path { get; }
public string Arguments { get; }
public bool IsRunning { get; private set; }
public int? ExitCode { get; private set; }
private Process Process;
private readonly object Locker = new object();
public CommandLineProcess(string path, string arguments)
{
Path = path ?? throw new ArgumentNullException(nameof(path));
if (!File.Exists(path)) throw new ArgumentException($"Executable not found: {path}");
Arguments = arguments;
}
public int Run(out string output, out string err)
{
lock (Locker)
{
if (IsRunning) throw new Exception("The process is already running");
Process = new Process()
{
EnableRaisingEvents = true,
StartInfo = new ProcessStartInfo()
{
FileName = Path,
Arguments = Arguments,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
CreateNoWindow = true,
},
};
if (!Process.Start()) throw new Exception("Process could not be started");
output = Process.StandardOutput.ReadToEnd();
err = Process.StandardError.ReadToEnd();
Process.WaitForExit();
try { Process.Refresh(); } catch { }
return (ExitCode = Process.ExitCode).Value;
}
}
public void Kill()
{
lock (Locker)
{
try { Process?.Kill(); }
catch { }
IsRunning = false;
Process = null;
}
}
public void Dispose()
{
try { Process?.Dispose(); }
catch { }
}
}
}
PS: 我正在使用Visual Studio 2017 / .NET 4.7.2。
