从上面发现

repository.exception.ComponentLookupException: org/eclipse/jetty/maven/plugin/JettyRunMojo : Unsupported major.minor version 51.0

很明显是版本问题. 检查jdk,版本是1.6，改为1.7后，重新运行，一切正常.

 

http://download.eclipse.org/jetty/

解压之后在webapps下新建root目录

在root目录中新建index.jsp文件

<html>
<body>
<%
    out.println("hello world")
%>
</body>
</html>

进入控制台运行

java -jar start.jar

 

在windows下可能出现下面错误，原因是执行java命令时优先使用windows自带的java，但是lib却使用我们配置的classpath.

org.apache.jasper.JasperException: PWC6345: There is an error in invoking javac.  A full JDK (not just JRE) is required

解决办法

C:\Program" "Files\Java\jdk1.7.0_60\bin\java -jar start.jar

http://localhost:8080 即可看到hello word
