## 场景 ##

想要修改Maven项目的Dynamic Web Module，直接右击项目--properties--Project Facets

将Dynamic Web Module直接通过下拉框选择为3.0却提示说需要java1.6或者newer。

## 解决 ##

来到Eclipse下的workspace下的项目目录下。

进入到.settings目录下

找到org.eclipse.wst.common.project.facet.core.xml，并打开

打开之前

修改之后

保存并关闭

打开maven项目下的web.xml，修改为

<?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" metadata-complete="true">
    </web-app>

pom.xml修改build节点，添加

<plugins>
           <plugin>
                  <groupId>org.apache.maven.plugins</groupId>
                  <artifactId>maven-compiler-plugin</artifactId>
                  <configuration>
                         <source>1.8</source>
                         <target>1.8</target>
                  </configuration>
           </plugin>
    </plugins>

回到Eclipse，右击项目---Maven--Update Project

此时再右击项目--properties--Project Facets
