我有一个包含以下内容的网络应用。使用 Maven war plugin 2.2 ，我正在构建war文件。但是war文件仅包含 web.xml 文件，而没有其他内容。
.
├── META-INF
│ └── webapp-classloading.xml
└── WEB-INF
├── beans.xml
└── web.xml
尝试了Maven DEBUG模式-X。可以看到我的war插件正在复制工件，但没有将它们添加为条目。

如您所见，即使复制了webapp-classloading.xml或beans.xml文件，它也不会添加en条目。
最奇怪的是我的另一个Webapp，它使用相同的依赖项，并且插件版本（同一个父版本）将这些工件正确复制到war文件中。在那里我可以看到条目已添加。
