Answer 1

Run cd android &&./gradlew clean

chmod +x gradlew

It will work

Answer 2

cd android;
chmod +x gradlew;
./gradlew clean && cd ..;

It worked for me this way.

Answer 3

If you are using Linux / Ubantu then you need give folder permission. so you just need to type the command on your root Directory of project folder: sudo chmod -R 777 folder_name

eg:kishan@kishan-ideacentre-588S-0554iKL:~/Workspace/HundredAcer$ sudo chmod -R 777 android

Then copy file named local properties from AndroidStudioProject/Your AppName/ then paste it to your projectName/Android/

you are done..!
