Gradle variables

[Giuseppe Sorce]

I'd like send keystore variable by pipeline.

I have this signingconfig

storeFile file(RELEASE_STORE_FILE)
storePassword RELEASE_STORE_PASSWORD
keyAlias RELEASE_KEY_ALIAS
keyPassword RELEASE_STORE_PASSWORD

In local i use 

./gradlew assembleRelase -PRELEASE_STORE_PASSWORD -PRELEASE_STORE_PASSWORD

and it works.. but with pipeline doesn't work 

How can avoid write signinconfig in gradle.properties and use gradle to send variables?
