./gradlew No such file or directory - Android studio 2.3

Question

When i try to build the android app from command line in the android studio . I get command not found. but im able to run the app with the play button.

 M01GMBS30ZVG8WP:paylahmerchant dheerajprasad$ ls
MobileSDK          gradle                  merchant.iml
MPChartLib              gradle.properties       popuplibrary
app                     gradlew                 settings.gradle
build                   gradlew.bat             webapilibrary
build.gradle            local.properties

M01GMBS30ZVG8WP:paylahmerchant dheerajprasad$ ./gradlew assemble
env: bash\r: No such file or directory

But when i run the same command for the different project , gradle command works as expected.

Please help on this.

Answer 1

The problem was all the commands was converted to windows commands.

running this command replaced the content to correct format.

sed $'s/\r$//' ./source > ./destination

env: bash\r: No such file or directory
