Java com.sun.org.apache.xerces.internal.dom.DocumentImpl不能强制转换为org.codehaus.plexus.util.xml.Xpp3Dom

Afetr使用Maven pom.xml的模型库see在这几周内，我在尝试将ConfigurantContainer写入pom.xml时遇到了这个错误

javadoc for Model说：

public void setConfigurationObject配置

因此，我使用文档org.w3c.dom.Document和xml解析器标准javax库制作了一些xml。你知道代码，网络上到处都是，但我把它贴在这里

然后用元素声明填充代码，还有很多附加子元素等等

并试图让它发挥作用。似乎做得不好。 第一次尝试使用

plugin.setConfiguration(doc);

但它不起作用。 然后我试着

Obejct obj = doc;    
plugin.setConfiguration(obj);

但它不起作用

然后我在网上搜索答案，猜

它不起作用

在整个网络中，大约有0人在使用这个库maven.model。我又来了，向感官寻求帮助

我的错误在哪里？我已经下载了库的源代码，试图查看错误在哪里，但它似乎应该是可以的。 我添加stackrace以供参考

好的，问题解决了，我保证在服药期间再也不要问任何问题

我的主要问题是我无法理解如何将配置设置为DOM对象。从javadoc中可以看出，它指的不是一个典型的DOM对象，而是一个Xpp3Dom对象

非常抱歉让你耽误了时间

顺便说一句，这似乎导致了某种错误，我建议更改javadoc，使其更易于理解。类似于将配置设置为Xpp3Dom对象

plugin.setConfiguration(doc);

Obejct obj = doc;    
plugin.setConfiguration(obj);
