Kotlin JVM Quarkus MicroProfile REST API implementation

• written in Kotlin for the JVM

• using Quarkus and MicroProfile 3.3

• exposes a REST API defined by a Kotlin interface with JAX-RS annotations

• Gradle build using Kotlin DSL

• targeting Java 11

Platform

The platform comprises all libraries/modules/packages that are by definition always present and are pre-approved to appear in all layers of the system, including domain.

• Jave SE 11 (https://docs.oracle.com/en/java/javase/11/docs/api/java.se/module-summary.html), but trying to use only

  • java.base (https://docs.oracle.com/en/java/javase/11/docs/api/java.base/module-summary.html)

  • java.logging (https://docs.oracle.com/en/java/javase/11/docs/api/java.logging/module-summary.html)

• Kotlin standard library for Common and JVM targets (https://kotlinlang.org/api/latest/jvm/stdlib/)

• JSR-330 javax.inject

• CDI javax.enterprise.context

How this app was generated

docker run --rm --name mvn -it -v $(pwd):/proj -w /proj maven:3-jdk-11 /bin/bash -c "\
	apt-get update; \
	apt-get install -y --no-install-recommends gradle; \
	mvn io.quarkus:quarkus-maven-plugin:1.3.1.Final:create \
		-DprojectGroupId=org.integrational \

		-DbuildTool=gradle"

This fails in the final Gradle build, which generates the Gradle wrapper. Hence:

cd kotlin-quarkus-mp-rest-service
docker run --rm --name gradle -it -v $(pwd):/proj -w /proj gradle:jdk11 gradle wrapper
