Hello I have a simple android project. In that project I added an External jar file following this Stackoverflow Add External jar

Which generates below line in build.gradle(app):

implementation files('libs\classes.jar')

This Compile and run fine in Android Studio. I am trying to build the project in command line using below command:

./gradlew assembleDebug

But build is failed for the external library.

Tried to change the file path using this, still no luck.

implementation files('libs/classes.jar')

Any Help will be appretiated thanks in advance.
