我在CruiseControl.NET中设置了两个项目：CI构建和每晚构建。
它们都执行相同的NAnt脚本，但参数不同。
CruiseControl.NET标签（当前由 DefaultLabeler 生成）作为版本的构建部分嵌入到AssemblyInfo中（例如， MajorVersion.MinorVersion.CCNET_Label.SVN_Revision ）。
对于更一致的版本控制，我希望两个项目共享相同的CruiseControl.NET标签值。
我已经调查了作为CruiseControl.NET安装的一部分提供的贴标机，但我找不到能满足我想要的标签。
如何在多个CruiseControl.NET构建之间共享标签值？
如果有更好的方法，我想知道。

我找不到能够做我需要的现有解决方案，所以我最终编写了一个自定义的CruiseControl.NET贴标机。
以下是它的完成方式：
using ThoughtWorks.CruiseControl.Core;
using ThoughtWorks.CruiseControl.Remote;
// this is the labeller name that will be used in ccnet.config
[ReflectorType("customLabeller")]
public class CustomLabeller : ILabeller
{
[ReflectorProperty("syncronisationFilePath", Required = true)]
public string SyncronisationFilePath { get; set; }
#region ILabeller Members
public string Generate(IIntegrationResult previousResult)
{
if (ShouldIncrementLabel(previousResult))
return IncrementLabel();
if (previousResult.Status == IntegrationStatus.Unknown)
return "0";
return previousResult.Label;
}
public void Run(IIntegrationResult result)
{
result.Label = Generate(result);
}
#endregion
private string IncrementLabel()
{
if(!File.Exists(SyncronisationFilePath))
return "0";
using (FileStream fileStream = File.Open(SyncronisationFilePath,
FileMode.OpenOrCreate,
FileAccess.ReadWrite,
FileShare.None))
{
// read last build number from file
var bytes = new byte[fileStream.Length];
fileStream.Read(bytes, 0, bytes.Length);
string rawBuildNumber = Encoding.ASCII.GetString(bytes);
// parse last build number
int previousBuildNumber = int.Parse(rawBuildNumber);
int newBuildNumber = previousBuildNumber + 1;
// increment build number and write back to file
bytes = Encoding.ASCII.GetBytes(newBuildNumber.ToString());
fileStream.Seek(0, SeekOrigin.Begin);
fileStream.Write(bytes, 0, bytes.Length);
return newBuildNumber.ToString();
}
}
private static bool ShouldIncrementLabel(IIntegrationResult previousResult)
{
return (previousResult.Status == IntegrationStatus.Success ||
previousResult.Status == IntegrationStatus.Unknown)
}
}
<labeller type="sharedLabeller">
<syncronisationFilePath>C:\Program Files\CruiseControl.NET\server\shared\buildnumber.txt</syncronisationFilePath>
<incrementOnFailure>false</incrementOnFailure>
</labeller>

我遇到了同样的问题，但我发现将<stateFileLabeller>与<assemblyVersionLabeller>结合使用证明是一个更简单的解决方案。
使用stateFileLabeller的唯一问题是，您无法在项目中为状态文件指定目录，因为CruiseControl.NET无法找到它。我将它保留在默认目录中，效果很好。

我修改了Arnold这个类，使它更像是defaultlabeller的副本：

using System.Text;
using Exortech.NetReflector;
using ThoughtWorks.CruiseControl.Core;
using ThoughtWorks.CruiseControl.Remote;
// This namespace could be altered and several classes could be put into the same if you'd want to combine several plugins in one dll
namespace ccnet.SharedLabeller.CruiseControl.plugin

#endregion

好处应该是您现在可以指定前缀以及“incrementonfailure”。此外，我添加了一个“increment”属性，可用于部署版本，根本不应增加版本号。如果您想自己修改它，我建议您查看它们的实现： CruiseControl.NET repository folder containing labellers
