Grails 1.3.7執行腳本時出錯War：無法找到javax.xml.parsers.SAXParserFactory的提供程序

Question

我的問題是我發出的每個grails命令，即使只有grails help，結果也是javax.xml.parsers.FactoryConfigurationError。我想使用JVM系統屬性 - Djaxp.debug=1（如記錄here）來解決尋找SAXParserFactoryImpl的方式。但是，添加指令如下：grails -Djaxp.debug=1 help不會產生額外的調試信息。

是否需要額外的步驟才能從grails命令行獲取jaxp調試語句？是否有另一種方法來發現爲什麼我得到這個錯誤？

這是我收到錯誤的完整堆棧跟蹤：

謝謝。

Answer 1

幾個月前我有同樣的問題。 事實證明，我的應用程序中有另一個SAXParser *庫。對我而言，這是一個更新的GPars圖書館。所以我刪除它，它再次運作。 我真的不知道，如果有可能在同一時間使用兩個實現......
