我在 CruiseControl.NET 中设置了两个项目：CI 构建和夜间构建。
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）。
为了更一致的版本控制，我希望两个项目共享相同的 CruiseControl.NET 标签值。
我调查了可作为 CruiseControl.NET 安装的一部分使用的标签器，但我找不到可以满足我需求的标签器。
如何在多个 CruiseControl.NET 构建之间共享标签值？
如果有更好的方法来做到这一点，我想知道。
我找到了一个方法。请看下面我的回答。
我找不到可以满足我需求的现有解决方案，因此我最终编写了一个自定义 CruiseControl.NET 贴标机。
这是如何完成的：
使用 ThoughtWorks.CruiseControl.Core；
使用 ThoughtWorks.CruiseControl.Remote；
// 这是将在 ccnet.config 中使用的贴标机名称
[ReflectorType("customLabeller")]
公共类 CustomLabeller : ILabeller
{
[ReflectorProperty("syncronisationFilePath", 必需 = true)]
公共字符串 SyncronisationFilePath { 获取；放; }
#region ILabeller 成员
公共字符串生成（IIntegrationResult previousResult）
{
if (ShouldIncrementLabel(previousResult))
返回增量标签（）；
如果（previousResult.Status == IntegrationStatus.Unknown）
返回“0”；
返回上一个结果。标签；
}
公共无效运行（IIntegrationResult 结果）
{
result.Label = 生成（结果）；
}
#endregion
私有字符串 IncrementLabel()
{
如果（！File.Exists（同步文件路径））
返回“0”；
使用 (FileStream fileStream = File.Open(SyncronisationFilePath,
FileMode.OpenOrCreate,
FileAccess.ReadWrite,
文件共享。无））
{
// 从文件中读取最后的内部版本号
var bytes = new byte[fileStream.Length];
fileStream.Read(bytes, 0, bytes.Length);
string rawBuildNumber = Encoding.ASCII.GetString(bytes);
// 解析最后的构建号
int previousBuildNumber = int.Parse(rawBuildNumber);
int newBuildNumber = previousBuildNumber + 1;
// 增加内部版本号并写回文件
bytes = Encoding.ASCII.GetBytes(newBuildNumber.ToString());
fileStream.Seek(0, SeekOrigin.Begin);
fileStream.Write(bytes, 0, bytes.Length);
返回 newBuildNumber.ToString();
}
}
私有静态 bool ShouldIncrementLabel(IIntegrationResult previousResult)
{
返回（previousResult.Status == IntegrationStatus.Success ||
previousResult.Status == IntegrationStatus.Unknown)
}
}
<labeller type="sharedLabeller">
<syncronisationFilePath>C:\Program Files\CruiseControl.NET\server\shared\buildnumber.txt</syncronisationFilePath>
<incrementOnFailure>假</incrementOnFailure>
</labeller>
我遇到了同样的问题，但我发现使用<stateFileLabeller>与 the 结合使用被<assemblyVersionLabeller>证明是一个更简单的解决方案。
使用 stateFileLabeller 的唯一问题是您不能为项目中的状态文件指定目录，因为 CruiseControl.NET 不会找到它。我把它放在默认目录中，效果很好。
我已经修改了 Arnold 类，使其更像是 defaultlabeller 的复制品：

好处应该是您现在可以指定前缀以及“incrementonfailure”。此外，我还添加了一个“增量”属性，可用于部署构建，它根本不应该增加构建号。如果你想自己修改它，我建议你看看他们的实现： CruiseControl.NET repository folder contains labellers
