Spring boot deployment on Heroku help

hi
as part of my ci/cd i want to deploy artifact after build stage which its only 1 jar to Heroku,

using on deploy stage
dpl --provider=heroku --app=xxxx --api-key=$HEROKU_API_KEY

what happened is that instead of deploying the jar its cloning the repo and triggering clean install

-----> Java app detected
-----> Installing JDK 11… done
-----> Executing: ./mvnw -DskipTests clean dependency:list install

so how i can control it? i want only to deploy the jar from build stage to heroku , or at lease control it not to trigger clean install to tigger package spring-boot:repackage for spring.
