今天在查看Android项目中三方库的依赖关系时，发现蜜汁好用的gradle命令权限被限制了：
qingmeideMac-mini:FireProtectionClient_Android qing.mei$ ./gradlew -q app:dependencies
//注意这行，被提示没有权限
-bash: ./gradlew: Permission denied最后在 stackoverflow-gradlew: Permission Denied找到了答案：
输入 chmod +x gradlew
该命令的作用是是Linux下去除执行权限。
//输入该命令
qingmeideMac-mini:FireProtectionClient_Android qing.mei$ chmod +x gradlew
//检查权限，发现该命令可以用了
qingmeideMac-mini:FireProtectionClient_Android qing.mei$ ./gradlew

通过这个问题，深深感觉到，只是单纯的懂得在Android项目中配置gradle是不够的，接下来更需要深入学习这门脚本语言。
