问题描述:maven项目出现如下错误

JavaServer Faces 2.0 requires Dynamic Web Module 2.5 or newer..Maven Java EE Configuration Problem
JavaServer Faces 2.0 can not be installed : One or more constraints have not been satisfied..line 1 Maven Java EE Configuration Problem

解决方案:

首先,将webapp下的web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!-- <!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">


替换为

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
<display-name>Archetype Created Web Application</display-name>
</web-app>


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3.0,将成后是<installed facet="jst.web" version="3.0"/>,再启动Eclipse.

最后,在Problems View的出错提示右键选Quick Fix,再按提示确定就OK;或者,右键项目->Maven->Update Project

=====================

此时,问题一般解决。如还不能解决,尝试在pom.xml中加入如下代码:

<build>
<finalName>chm</finalName>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
</build>
