      Problem

      Running Quarkus.io on a JVM works with Java 8 and Quarkus.io version 1.13.4 (latest as of Today). However, Java 8 support was announced to be discontinued starting with version 1.6 [1]. Native executable support requires already Java 11 [2]. With Quarkus.io 2.0, Java 8 support is discontinued in favor of Java 11.

      The Maven plugin already warns the users:

      [INFO] --- quarkus-maven-plugin:1.13.4.Final:build (default) @ camunda-bpm-quarkus-rest-example ---
[WARNING] [io.quarkus.deployment.QuarkusAugmentor] Using Java versions older than 11 to build Quarkus applications is deprecated and will be disallowed in a future release!

      Solution idea

      When Quarkus.io starts to enforce Java 11, we can bump the Java version in the assembly job and set the compiler target to Java 8.
