JavaServer Faces 2.0 can not be installed解决方案

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

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

替换为

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

然后,关闭Eclipse,改项目下的.settingsorg.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:

 1     <build>
 2         <finalName>chm</finalName>
 3         <plugins>
 4             <plugin>
 5                 <artifactId>maven-compiler-plugin</artifactId>
 6                 <version>2.0.2</version>
 7                 <configuration>
 8                     <source>1.6</source>
 9                     <target>1.6</target>
10                 </configuration>
11             </plugin>
12         </plugins>
13     </build>
