> camel-jbang - camel export --runtime=quarkus ignores --java-version in the
> generated Dockerfile
> -----------------------------------------------------------------------------------------------
>
> Key: CAMEL-25495
> URL: https://issues.apache.org/jira/browse/CAMEL-25495
> Project: Camel
> Issue Type: Bug
> Components: camel-jbang
> Affects Versions: 4.22.1
> Reporter: Thomas Raddatz
> Priority: Minor
> Fix For: 4.23.0
>
>
> {{camel export \-\-runtime=quarkus}} writes {{src/main/docker/Dockerfile}}
> and {{Dockerfile.jvm}} with a fixed base image,
> {{registry.access.redhat.com/ubi9/openjdk-21-runtime:1.24}}, whatever
> {{\-\-java-version}} says. With {{\-\-java-version=25}} the exported project
> is compiled for Java 25 ({{maven.compiler.release}} is 25), but the image
> runs it on a Java 21 runtime, so the container cannot start
> ({{UnsupportedClassVersionError}}).
> Camel Main and Spring Boot pick their Dockerfile template by
> {{\-\-java-version}} ({{Dockerfile21.ftl}} / {{Dockerfile25.ftl}},
> {{Dockerfile-spring-boot21.ftl}} / {{Dockerfile-spring-boot25.ftl}},
> CAMEL-23088). The Quarkus fast-jar Dockerfile
> ({{quarkus-docker/Dockerfile.jvm}}, added with CAMEL-23192) is copied
> verbatim and never got a Java 25 variant. The Quarkus {{uber-jar}} package
> type is not affected: it uses the Camel Main template.
> To reproduce:
> {code:bash}
> camel init cheese.yaml
> camel export cheese.yaml --runtime=quarkus --java-version=25
> --gav=org.example:cheese:1.0.0 --dir=cheese
> grep '^FROM' cheese/src/main/docker/Dockerfile
> cheese/src/main/docker/Dockerfile.jvm
> {code}
> {code:none}
> cheese/src/main/docker/Dockerfile:FROM
> registry.access.redhat.com/ubi9/openjdk-21-runtime:1.24
> cheese/src/main/docker/Dockerfile.jvm:FROM
> registry.access.redhat.com/ubi9/openjdk-21-runtime:1.24
> {code}
> Expected: {{ubi9/openjdk-25-runtime}} for {{\-\-java-version=25}}, as for the
> other runtimes.
> Checked on 4.22.1, on the camel-4.22.x branch and on main. The workaround is
> to raise the base image of the exported Dockerfiles after the export.
