哈德森插件問題

我創建了幾乎與JobTypeColumn相同的插件。只有一個區別 - 它顯示工作描述而不是工作類型。但我無法將此列添加到我的列表視圖。我手動編輯我的config.xml後，我有一個NullPointerException。哈德森插件問題

你看過Hudson source code嗎？（描述符文件是here，但您必須首先訪問wiki頁面以閱讀用戶登錄名/密碼）。

當然，我不知道你是否使用最新的版本，但比較源代碼與堆棧跟蹤，它看起來像一個JSON對象的問題，其中哈德森無法實例化其中一個描述符。

直接編輯config.xml不是一個好方法。首先找出如何讓UI正確保存配置。這可能也會解決你的NPE問題，因爲你的插件可能沒有被哈德森正確拾取。
