然后我对代码的Classes进行插装
java emma instr -m overwrite -ip /data/application/kitchen/WEB-INF/classes -Dmetadata.out.file=/soft/coverage.em
在soft 下也看到了coverage .em
重启项目
之后，输入指令：
java emma ctl -connect localhost:47653 -command coverage.get,data/coverage.ec
就报错了EMMA: processing control command sequence ...
EMMA: executing [coverage.get (root/coverage.ec,true,true)] ...
[EMMA v2.1, build 5320 (stable)]
