proj.android-studio: gradlew permission denied

[wingyplus]

When I ran cocos to run on android platform with command:

$ NDK_ROOT=~/android-ndk-r13b cocos run -p android --android-studio -j 4

Expected:

cocos can run gradlew smoothly.

Actual:

/bin/sh: /Users/wingyplus/game-engine-experiment/FlappyClone/proj.android-studio/gradlew: Permission denied
Error running command, return code: 126.

The version that I use is

cocos2d-x-3.13.1
Cocos Console 2.1
