Have I chosen the correct configuration for a project using spring?

Question

Spring

I'm creating a restfull web-framework on Kotlin as a project, have I chosen the correct settings configuration in spring for it? Or is it not important for the server to cover more devices, or is the jar outdated?

Maven as a builder, because Gradle is not always stable
Packaging: JAR archive, as it is easier to run
JVM: 8 to cover more devices
And also from libraries:
Spring Web, Spring Data JPA, PostgreSQL Driver, Spring Actuator

I create restfull web-framework on Kotlin

Choose what you like and what you are best at.

Maven as builder because Gradle is not always stable

Not a fact about the grade. But maven will do.

Packaging: JAR archive because it's easier to run

This depends on your goals. If you need a self-contained application, then jar is fine. When deploying, create an initd service and the application will take off. In the case of WAR, it would be necessary to raise a separate tomcat or something else ...

JVM: 8 to cover more devices

JDK 11 as far as I know is better in this case. Maybe I'm wrong

Spring Web, Spring Data JPA, PostgreSQL Driver, Spring Actuator

Well, here you need to choose what you need.
