• 修改步骤
  • 指定新目录位置app.dir
  • 添加编译插件，指定编译字节码版本
  • 添加clean插件，指定clean路径为${app.dir}位置
  • 添加resources插件
    • 先拷贝webapp目录/静态资源和动态页面 到${app.dir}位置
    • 拷贝resources下的配置文件到target/classes目录
    • 拷贝target/classes下的class和配置文件到${app.dir}/WEB-INF/classes目录
  • 添加dependency插件，将jar包拷贝到${app.dir}/WEB-INF/lib目录
• 修改build节点
