有一个MSBuild脚本,包括Delphi和C#项目的数字,单元测试等。
问题是:如果警告被引发,如何标记构建失败(出于测试目的,而不是发布版本)?在自定义任务中使用LogError而不是LogWarning似乎不是一个好的选择,因为构建应尽可能多地测试(直到真正的错误)在一段时间内尽可能多地报告警告(构建项目在CruiseControl.NET中使用) )。
可能是,解决方案是创建我自己的记录器,它会在里面存储警告标志,但我找不到是否有办法在构建结束时读取这个标志?
P.S。收到警告后立即使构建失败没有问题(Delphi编译器输出由自定义任务处理,而/ warnaserror可用于C#),但所需的行为是“构建所有内容;收集所有警告;构建失败”报告所有警告,而不仅仅是关于第一个警告。
P.P.S。至于我真的不需要警告的数量,而只是它们存在的标志,我决定简化信令机制,并使用琐碎的Mutex而不是共享内存。代码如下:
using System;
using Microsoft.Build.Framework;
using Microsoft.Build.Utilities;
using System.Threading;
namespace Intrahealth.Build.WarningLogger
{
public sealed class WarningLoggerCheck : Task
{
public override bool Execute()
{
Log.LogMessage("WarningLoggerCheck:" + mutexName + "...");
result = false;
Mutex m = null;
try
{
m = Mutex.OpenExisting(mutexName);
}
catch (WaitHandleCannotBeOpenedException)
{
result = true;
}
catch (Exception)
{
}
if (result)
Log.LogMessage("WarningLoggerCheck PASSED");
else
Log.LogError("Build log contains warnings. Build is FAILED");
return result;
}
private bool result = true;
[Output]
public bool Result
{
get { return result; }
}
private string mutexName = "WarningLoggerMutex";
public string MutexName
{
get { return mutexName; }
set { mutexName = value ?? "WarningLoggerMutex"; }
}
}
public class WarningLogger : Logger
{
internal static int warningsCount = 0;
private string mutexName = String.Empty;
private Mutex mutex = null;
public override void Initialize(IEventSource eventSource)
{
eventSource.WarningRaised += new BuildWarningEventHandler(eventSource_WarningRaised);
}
private void SetMutex()
{
if (mutexName == String.Empty)
{
mutexName = "WarningLoggerMutex";
if (this.Parameters != null && this.Parameters != String.Empty)
{
mutexName = this.Parameters;
}
}
mutex = new Mutex(false, mutexName);
}
void eventSource_WarningRaised(object sender, BuildWarningEventArgs e)
{
if (e.Message != null && e.Message.Contains("MSB3146"))
return;
if (e.Code != null && e.Code.Equals("MSB3146"))
return;
if (warningsCount == 0)
SetMutex();
warningsCount++;
}
}
}

AFAIK MSBuild没有内置支持来检索构建脚本的给定点的警告计数。但是,您可以按照以下步骤来实现此目标:
最困难的一步是第3步。为此,有几个选项,您可以在IPC - Inter Process Comunication下自由搜索它们。下面是一个如何实现这一目标的工作示例。每个项目都是不同的类库。
<强>共享内存强>
http://weblogs.asp.net/rosherove/archive/2003/05/01/6295.aspx
我为named创建了一个包装器 共享内存是一部分 更大的项目。它基本上允许 序列化类型和对象图 存储在共享中并从共享中检索 记忆(包括你所期望的 跨进程)。是否更大 项目永远完成是另一个 问题; - )。
<强> SampleLogger 强>
实现跟踪警告计数的自定义记录器。
namespace SampleLogger
{
using System;
using Microsoft.Build.Utilities;
using Microsoft.Build.Framework;
using DM.SharedMemory;
public class MySimpleLogger : Logger
{
private Segment s;
private int warningCount;
public override void Initialize(IEventSource eventSource)
{
eventSource.WarningRaised += new BuildWarningEventHandler(eventSource_WarningRaised);
this.s = new Segment("MSBuildMetadata", SharedMemoryCreationFlag.Create, 65535);
this.s.SetData(this.warningCount.ToString());
}
void eventSource_WarningRaised(object sender, BuildWarningEventArgs e)
{
this.warningCount++;
this.s.SetData(this.warningCount.ToString());
}
public override void Shutdown()
{
this.s.Dispose();
base.Shutdown();
}
}
}
<强> SampleTasks 强>
实现自定义任务,该任务读取MSbuild项目中引发的警告数。自定义任务从类库 SampleLogger 中实现的自定义记录器写入的共享内存中读取。
namespace SampleTasks
{
using System;
using Microsoft.Build.Utilities;
using Microsoft.Build.Framework;
using DM.SharedMemory;
public class BuildMetadata : Task
{
public int warningCount;
[Output]
public int WarningCount
{
get
{
Segment s = new Segment("MSBuildMetadata", SharedMemoryCreationFlag.Attach, 0);
int warningCount = Int32.Parse(s.GetData() as string);
return warningCount;
}
}
public override bool Execute()
{
return true;
}
}
}

答案 1 :(得分:1)
C#编译器(csc.exe)有一个/ warnaserror开关将警告视为错误并使构建失败。这也可以作为.csproj文件中的设置使用。我认为德尔福有类似的能力。
