TopShelf MSDeploy在出錯時安裝退出代碼

Question

我正嘗試從CI安裝使用TopShelf的服務。但是，無論何時在安裝期間發生異常，TopShelf回滾事務並繼續構建過程，返回0x0狀態。

這意味着就CI服務器而言，部署是成功的。

我使用的MSBuild命令的一個例子是：

<Message Text ="Installing Service" /> 
<Exec Command=""$(MSDeployPath)" -verb:sync -source:runCommand="$(RemoteServicePath) install /instance:$(DeployEnvironment)",dontUseCommandExe=false,waitAttempts=10,waitInterval=10000 -dest:auto,computername=%(ComputerName) -verbose -retryInterval:10000 -retryAttempts:10"></Exec> 

我收到的輸出是：

[Exec] Running a transacted installation. <br> 
[Exec] <br> 
[Exec] Verbose: Received response from agent (HTTP status 'OK'). <br> 
[Exec] Info: <br> 
[Exec] Beginning the Install phase of the installation. <br> 
[Exec] <br> 
[Exec] Info: Installing service Foo...<br> 
[Exec] <br> 
[Exec] Info: Creating EventLog source Foo in log Application...<br> 
[Exec] <br> 
[Exec] Info: <br> 
[Exec] An exception occurred during the Install phase.<br> 
[Exec] <br> 
[Exec] Info: System.ComponentModel.Win32Exception: The specified service already exists<br> 
[Exec] <br> 
[Exec] The Rollback phase of the installation is beginning.<br> 
[Exec] Restoring event log to previous state for source Foo.<br> 
[Exec] <br> 
[Exec] The Rollback phase completed successfully.<br> 
[Exec] <br> 
[Exec] The transacted install has completed.<br> 

任何想法如何，我可以使異常在構建失敗？

最新版本的Topshelf（3.0.2）添加了一個TopshelfExitCode，它是一個枚舉，可以在控制檯應用程序中將其轉換爲（int）並從Main返回。

如果安裝/卸載失敗，則錯誤代碼爲非零（枚舉具有所有可能的值）。所以，現在它應該可以很好地與批處理文件/構建，當事情不正確安裝時期望非零退出代碼。
