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.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:
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>
