停止Windows服務不運行的原因構建失敗

Question

使用下面的搖籃動作，

developerBuild << { 
    exec{ 
     commandLine = ['cmd', '/c', 'net', 'stop', 'Foo'] 
    } 
} 

如果我執行這項任務，Windows服務Foo沒有運行，我會得到以下例外，

The Foo service is not started.

BUILD FAILED 

這會導致整個任務的執行停止，爲什麼？無論操作中的命令行調用的退出代碼如何，是否有辦法繼續執行該任務？

Answer 1

您可以在一個ExecSpec禁止出口值檢查的過程如下：

developerBuild << { 
    exec{ 
    commandLine = ['cmd', '/c', 'net', 'stop', 'Foo'] 
    ignoreExitValue = true 
    } 
} 

Answer 2

這可能是一個黑客位的，但我認爲它的工作原理：

developerBuild << { 
    try { 
     exec{ 
      commandLine = ['cmd', '/c', 'net', 'stop', 'Foo'] 
     } 
    } catch (TaskExecutionException e) { 
     //Do whatever you want 
    } 
} 

它看起來像gradle這個默認的執行失敗拋出異常（這是我會做什麼了，我實現它） 。解決方案是捕捉這個「業務異常」。
