詹金斯getDescriptor（）返回NullPointerException異常

Question

我的描述符填充兩個列表，我試圖調用與以下的描述：

ZAPDriverDescriptorImpl zapDriver = getDescriptor();

然後我打電話

zapDriver.getAllFormats()和zapDriver.getAllExportFormats())獲得兩個列表。我將它們連接成只有唯一元素的列表。

滿級可以發現on GitHub

的問題是，這個當我（僅主機）運行詹金斯在當地，但是當我做了master-slave，這個代碼將執行的奴隸，碰上工作一個NullPointerException

Answer 1

你調用來自從執行Jenkins.getInstance()。它不可用，因爲從機不運行Jenkins實例。
