Grails 1.3.7执行脚本时出错War：无法找到javax.xml.parsers.SAXParserFactory的提供程序

Question

我的问题是我发出的每个grails命令，即使只有grails help，结果也是javax.xml.parsers.FactoryConfigurationError。我想使用JVM系统属性 - Djaxp.debug=1（如记录here）来解决寻找SAXParserFactoryImpl的方式。但是，添加指令如下：grails -Djaxp.debug=1 help不会产生额外的调试信息。

是否需要额外的步骤才能从grails命令行获取jaxp调试语句？是否有另一种方法来发现为什么我得到这个错误？

这是我收到错误的完整堆栈跟踪：

谢谢。

几个月前我有同样的问题。 事实证明，我的应用程序中有另一个SAXParser *库。对我而言，这是一个更新的GPars图书馆。所以我删除它，它再次运作。 我真的不知道，如果有可能在同一时间使用两个实现......
