1、先运行build.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="app" default="compiler">
<target name="compiler">
<property name="dir.compiler.home" location=".." />
<exec executable="cmd" failonerror="true" dir="${dir.compiler.home}">
<arg line="/c mvn clean install -Dmaven.test.skip=true" />
</exec>
</target>
</project>
2、然后jetty:run-war -Djetty:port=9999
每次修改文件之后，都要运行上面的1,2步骤才能生效
