Android – You uploaded an APK that was signed in debug mode. You need to sign your APK in release mode error

androidgoogle-playjarsignermaven

I am trying to upload an Application on the Google Play store. I am building the .apk and signing it using Maven. I have used maven-jarsigner-plugin to sign the .apk file. I am using the key that I created using Eclipse wizard for signing another Android app. I zipalign the .apk file using the following command:
zipalign [-f] [-v] infile.apk outfile.apk

When I try to uplaod the application on the playstore, I get the error You uploaded an APK that was signed in debug mode. You need to sign your APK in release mode. Can anyone please tell me how to sign the apk in release mode? I am new to Maven (started using it today).
Thanks

Change to: signingConfig signingConfigs.release

from signingConfig signingConfigs.debug

in your build.gradle app level
