Afetr 在这几周内为我的 Maven pom.xml 使用模型库（请参阅此内容）后，我在尝试将 ConfiguratonContainer 写入 pom.xml 时遇到了这个错误。
模型的 javadoc 说：
public void setConfiguration(对象配置)
Set the configuration as DOM object.
Parameters:
configuration -
所以我用 Document (org.w3c.dom.Document) 和 xml 解析器标准 javax 库制作了一些 xml。你知道代码（它通过所有网络），但我把它贴在这里......
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder parser = factory.newDocumentBuilder();
Document doc =parser.newDocument();
然后用 Element 声明、大量 appendChild 等填充代码。
并试图让它发挥作用。好像不太好 首先尝试使用
plugin.setConfiguration(doc);
但它没有用。然后我尝试了
Obejct obj = doc;
plugin.setConfiguration(obj);
但它没有用。
然后我在网上搜索答案，并猜测......
它没有用。
全网大约有 0 人在使用这个库（maven.model）。所以我又来了，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，但它似乎没问题（应该如此）。我添加了 stackrace 以供参考
