How to solve “Dynamic Web Module 3.1 requires Java 1.7 or newer” in Eclipse

先看后面有没有，

<build>
    <finalName>XiaoBenManager</finalName>
     <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
  </build>

错误级就是下面这个错误，不过关键是设置最后一步，如果还报错的话，关闭工程，然后打开工程，就Ok了
