Eclipse通过Maven插件创建webapp项目中遇到的问题

1. JSP Problem The super class “javax.servlet.http.HttpServlet” was not found on the Java Build Path

   解决办法:
   Properties – Java Build Path – Add Library – Server Runtime – Apache Tomcat vX.0

2. Faceted Project Problem Java compiler level does not match the version of the installed Java project facets。

   解决办法:
   打开项目目录下面的 .settings/org.eclipse.wst.common.project.facet.core.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <faceted-project>
    <fixed facet="wst.jsdt.web"/>
    <installed facet="java" version="1.5"/>
    <installed facet="jst.web" version="2.3"/>
    <installed facet="wst.jsdt.web" version="1.0"/>
   </faceted-project>

   修改 java 和 jst.web 到指定的版本。

    <installed facet="java" version="1.8"/>
    <installed facet="jst.web" version="3.0"/>

3. Dynamic Web Module 3.0 requires Java 1.6 or newer error while creating new project

   解决办法：
   在pom.xml 文件中指定编译时使用的java版本。

   <build>
       <plugins>
           <plugin>
               <artifactId>maven-compiler-plugin</artifactId>
               <configuration>
                   <source>1.8</source>
                   <target>1.8</target>
               </configuration>
           </plugin>
       </plugins>
   </build>
