JavaServer Faces 2.2 can not be installed

 

JavaServer Faces 2.2 can not be installed : One or more constraints have not been satisfied.
JavaServer Faces 2.2 requires Dynamic Web Module 2.5 or newer.

先改web.xmlwebapp节点:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">

然后关闭Eclipse,改项目下的.settings\org.eclipse.wst.common.project.facet.core.xml.将版本改成为3.1,将成后是<installed facet="jst.web" version="3.1"/>,再启动Eclipse. 

右键项目->Maven->Update Project
