Question

我在JBoss AS 7下使用Arquillian和TestNG来测试Maven项目，它运行得很好。我将 htmlunit 添加到我的POM之后：

<dependency>
    <groupId>net.sourceforge.htmlunit</groupId>
    <artifactId>htmlunit</artifactId>
    <version>2.9</version>
    <scope>provided</scope>
</dependency>

Arquillian测试立即开始崩溃，出现以下错误：

我对JBoss和Maven的了解有限，但似乎问题是 htmlunit 依赖于 xalan ，这显然也被Arquillian使用，但是我不知道为什么会搞砸。有什么想法吗？

Answer 1

事实证明，存档 serializer-2.7.1.jar 是 xalan 的一部分，在JBoss中打包不正确（无法解压缩） Maven存储库。像这样的错误是一个真正的调试难题，因为没有错误消息指向实际问题（谢谢，Java）。无论如何，我通过将相同的存档从JBoss安装复制到本地Maven存储库来解决了这个问题。

为什么在将htmlunit添加到POM后Arquillian会崩溃？
