  使用 emma 2.1 (emma-stable-2.1.5320-lib)
  1. 新建 /home/q/java/emmalib 目录, 将emma.jar 与 emma_ant.jar 放入
  2. 复制 /server/bin/mobileserver/runServer.sh 到 runServer_emma.sh
  修改启动语句
  nohup java -Xmx1800M -Xms800m -Xbootclasspath/p:/home/q/java/emmalib/emma.jar -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.EPollSelectorProvider -XX:+AggressiveOpts -XX:+UseParallelGC -server -classpath "$jarFile" com.qunar.common.mobileArc.MobileServer conf/TaLog.property conf/TripServer.property >> $LOG_HOME/error.log 2>&1 &
  复制 /server/bin/mobileserver/stopServer.sh 到 stopServer_emma.sh
   添加覆盖率导出命令
   插入 emma 统计代码
   使用root账号
   1. 备份mobileserver.jar
   cp /server/TripAssistant/mobile-server.jar $MOB_JAR_BAK/mobile-server.jar.{$timestamp}
   2. 执行插入命令
  java -cp /home/q/java/emmalib/emma.jar emma instr -m overwrite -cp mobile-server.jar -out coverage.em
  输出如下:
  EMMA: processing instrumentation path ...
   EMMA: instrumentation path processed in 3117 ms
   EMMA: [1000 class(es) instrumented, 126 resource(s) copied]
   EMMA: metadata merged into [/server/TripAssistant/coverage.em]
    3. 运行mobileserver runServer_emma.sh
   sudo sh /server/bin/mobileserver/stopServer.sh && sudo sh /server/bin/mobileserver/runServer_emma.sh
   在 /server/mobileserverlog/error.log中可见:
   EMMA: collecting runtime coverage data ...
   EMMA: runtime controller started on port [47653]
   emma control 进程已启动
    [root@l-wap4.beta.cn1.qunar.com /server/mobileserverlog]# netstat -na | grep 47653
    tcp 0 0 0.0.0.0:47653 0.0.0.0:* LISTEN 20926/java
    4. 执行 覆盖率文件导出命令
    java -cp /home/q/java/emmalib/emma.jar emma ctl -connect localhost:47653 -command coverage.get,coverage.ec
   可见输出:
   EMMA: processing control command sequence ...
   EMMA: executing [coverage.get (coverage.ec,true,true)] ...
   EMMA: coverage.get: local copy of coverage data merged into [/server/TripAssistant/coverage.ec]
   EMMA: coverage.get: command completed in 79 ms
   EMMA: control command sequence complete

   并且当前目录生成文件 coverage.ec
    5. 生成报告
    java -cp /home/q/java/emmalib/emma.jar emma report -r html -in coverage.em,coverage.ec
    指定源代码生产覆盖率报告(需先上传源码)
   java -cp /home/q/java/emmalib/emma.jar emma report -r html -in /server/TripAssistant/coverage.em,/server/TripAssistant/coverage.ec -Dreport.html.out.file=mycoverage/coverage.html -sp /home/liang.zhou/mob_code_dir/mobs_trunk/src/main/java
    emma 方式启动 mobserver
   ==================================
   1. 判断mobserver.jar size, 大于5M 为已插入过, 小于5M为未插入(需要执行插入)
   2. 执行插入
   3. 启动
    4. 检查启动状态
    47653 端口打开
   mobileserver 进程打开
    emma 方式停止 mobserver
    ==================================
   1. 检查47653端口打开状态, 检查coverage.em是否存在
  2. 导出覆盖率文件 coverage.ec, 备份coverage.em (加上时间戳)
   3. 导出覆盖率HTML report (加上对应时间戳)
   4. kill mobserver 进程
   ls -lt mobile-server.jar
   判断 $? == 0
    判断mobile-server.jar size是否大于 5M
    #!/bin/bash
   function stop_mob_server(){
   #!/bin/bash
   function stop_mob_server(){
   pid=`ps aux | grep MobileServer | grep -v grep | awk '
   Unknown macro: {print $2}
  '`
   ` kill -9 $
   Unknown macro: {pid}
   `
   sleep 1
   echo "Stop mobileserver success."
   }
   #判断 emma ctl 是否启动
   port_check_result=`netstat -na | grep 47653 | awk '
   Unknown macro: {print $1}
   '`
   if [ -z $
   Unknown macro: {port_check_result}
   ]; then
    echo "Emma ctl port 47653 is not LISTEN. Coverage.ec export operation aborted."
   else
   #emma ctl 为启动状态,导出 coverage.ec, 并备份至 /home/q/mobsrv_cov
   if []
