Got the following error while trying to build our common code.
尝试构建我们的公共代码时出现以下错误。
Description Resource Path Location Type
JavaServer Faces 2.0 can not be installed : One or more constraints have not been satisfied. Apps line 1 Maven Java EE Configuration Problem
JavaServer Faces 2.0 requires Dynamic Web Module 2.5 or newer. Apps line 1 Maven Java EE Configuration Problem

JavaServer Faces 2.0 requires Dynamic Web Module 2.5 or newer. Apps line 1 Maven Java EE Configuration Problem
I tried to find the error inside the code but there is no error. I suspect it's a dependency that is missing. Could someone please explain further if my thoughts are correct?
我试图在代码中找到错误，但没有错误。我怀疑这是缺少的依赖项。如果我的想法正确，有人可以进一步解释吗？

Somewhere in your project there is a web.xmldescriptor, and it declares version number for compliance with some edition of servlet-api.
Your application tries to use JSF2 which requires web.xmlto declare version 2.5 or newer.
Apparently yours is too old.
项目中的某个地方有一个web.xml描述符，它声明版本号以符合某些版本的 servlet-api。您的应用程序尝试使用需要web.xml声明 2.5 或更新版本的JSF2 。显然你的太老了。
Find this file and check what's there in the root element <web-app>.
There are examples of this descriptor for version 2.5 and 3 here on SO: link1, link2, link3.
找到这个文件并检查根元素中的内容<web-app>。在 SO 上有 2.5 版和 3 版的此描述符的示例：link1、link2、link3。
