Jenkins groovy.lang.MissingPropertyException：沒有這樣的屬性：對於類：Script1

Question

該程序的目的是替換所有 TFS 用戶的密碼。 如果我直接在代碼中使用用戶名和密碼，它就可以工作，但是當我將它轉換為參數化構建時會出現此錯誤。

Answer 1

引發groovy.lang.MissingPropertyException的原因之一是當您嘗試訪問其范圍之外的變量或您尚未定義該變量時。

Answer 2

我想您可能需要在提到的屬性上使用Field注釋。 也請看這里。

Answer 3

您需要在訪問參數之前檢查參數是否已定義：

if ( System.getenv('VARIABLE') ) {
  println "VARIABLE parameter exists, and its value is: " + VARIABLE
}

這些方法也可能適用於 groovy 腳本：

• binding.variables.containsKey('VARIABLE')
• currentBuild.buildVariableResolver.resolve('VARIABLE')
• build.environment.get('VARIABLE')
