Overwriting test task in gradle - scala

Question

I want to overwrite test task in gradle (I am using Gradle 4.3 version at this moment) to change the behavior of this task.
Specifically, I am using scoverage gradle plugin in a Scala project and I want to execute $ gradle test to call test task and testScoverage task, both at the same time.
I attached task test(overwrite: true) << { testScoverage } statement to the last of build.gradle file but I always get the same message:
gradle test
> Configure project :
The Task.leftShift(Closure) method has been deprecated and is scheduled to be removed in Gradle 5.0. Please use Task.doLast(Action) instead.
at build_clmw9wbi7768vkj4j7g7sy8v2.run(C:\Users\sergio_rodriguez\Repositorios\my-autodevops-poc\build.gradle:52)
(Run with --stacktrace to get the full stack trace of this deprecation warning.)
I pretend to generate coverage report in a single statement to be able to use Auto Devops Gitlab.
How can I do this?
My build.gradle file is as given below:
