Not able to build the project

I am following the tutorial :


OS: Windows 10
gradle was successfully installed
but when I tried doing $ ./gradlew build by typing
C:\gradle-site-plugin> ./gradlew build

It give me error
Task:signArchives FAILED
deprecated gradle features were used in this build, making it incompatible with Gradle 6.0.
What should I do in order to do the build.

Tks.

Running with -s will give you a full stacktrace that may help. Running with -i or -d to enable info or debug logging may also help you.
