Answer 1

把shell里面的cp test.war /home/was/test/tomcat/webapps/dqmhsm/test.war改成
cp test.war /home/was/test/tomcat/webapps/dqmhsm/

Answer 2

#echo rm -rf $MY_TOMCAT/webapps/$PROJECT_NAME/*  
rm -rf $MY_TOMCAT/webapps/$PROJECT_NAME/*&&echo delete file success!  
echo cp $WAR $MY_TOMCAT/webapps/$PROJECT_NAME/$WAR  
cp $1 $MY_TOMCAT/webapps/$PROJECT_NAME/$WAR  
请注意，这几句是在函数 “dep_project()”里面的，而函数里面的位置变量是在调用函数时传入的。并不和脚本运行时的一致。上例中调用“dep_project”并没有传入参数。所以在函数中"$1"是空值。

可以将  
cp $1 $MY_TOMCAT/webapps/$PROJECT_NAME/$WAR  
改为
cp $WAR $MY_TOMCAT/webapps/$PROJECT_NAME/$WAR

或将：  
dep_project;  
改为
dep_project $WAR;  
。
