由于 Xerces 错误，Spring Roo 无法生成 Selenium 测试

Question

看完 Roo Google IO 后，我决定尝试一下使用 本教程，但我在尝试时遇到了困难创建 Selenium 测试。

~.web roo> selenium test --controller ~.web.PizzaOrderController
Created SRC_MAIN_WEBAPP/selenium
Created SRC_MAIN_WEBAPP/selenium/test-pizzaorder.xhtml
Created SRC_MAIN_WEBAPP/selenium/test-suite.xhtml
Undo create SRC_MAIN_WEBAPP/selenium/test-suite.xhtml
Undo create SRC_MAIN_WEBAPP/selenium/test-pizzaorder.xhtml
Undo create SRC_MAIN_WEBAPP/selenium
com.sun.org.apache.xerces.internal.dom.DeferredCommentImpl cannot be cast to org.w3c.dom.Element

此论坛中的一个人建议从类路径中删除 Xerces，因为 Java 6 有其自己的基于Xerces的XML解析器。但是，我还没有找到从类路径中删除某些内容的明确方法，只有设置它（我认为每次都会很乏味）。

有谁知道从类路径中删除 jars 的明确方法？有没有人遇到过这个Roo问题并以其他方式解决过？

您能否输入“开发模式”，按 Enter 键，然后重新运行 Selenium 命令并包含后面更详细的堆栈跟踪？
