code.quarkus.io: gradle native build fails

[Karm]

Describe the bug

Hello,

I wanted to use the https://code.quarkus.io/ service to build a Quarkus native image on Windows, using Linux container builder image . I don't know much about Gradle, so I used the README, to no avail.

Expected behavior

It works.

Actual behavior

It doesn't work.

How to Reproduce?

Gradle 🔴

C:\tmp
λ powershell -Command "Invoke-WebRequest -Uri 'https://code.quarkus.io/d?e=rest&b=GRADLE&cn=code.quarkus.io' -OutFile 'code-with-quarkus.zip'"

C:\tmp
λ powershell -c "Expand-Archive -Path code-with-quarkus.zip -DestinationPath . -Force"

C:\tmp
λ cd code-with-quarkus

C:\tmp\code-with-quarkus
λ gradlew build -Dquarkus.native.enabled=true -Dquarkus.native.container-build=true
Starting a Gradle Daemon (subsequent builds will be faster)

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':quarkusBuild'.
> Outputting both native and JAR packages is not currently supported

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
> Get more help at https://help.gradle.org.

No idea if the README is broken or the Gradle integration is broken.

Yeah, we have an issue. Either with the README or with the code. And I think expecting people to use -Dquarkus.native.enabled=true -Dquarkus.package.jar.enabled=false to enable native is a bit too much.

The problem is due to these lines: https://github.com/quarkusio/quarkus/blob/main/devtools/gradle/gradle-application-plugin/src/main/java/io/quarkus/gradle/tasks/QuarkusBuild.java#L104-L106 .

From what I can see, we are not enforcing this in the Maven plugin. I think we had to at some point but maybe we relaxed things there and forgot to do it in the Gradle plugin?

@dmlloyd AFAICS, you added this check, is it still needed? (we are not setting quarkus.package.jar.enabled to false in the Maven projects AFAICS).

Note that when using the CLI, we are passing -Dquarkus.package.jar.enabled=false to the Gradle runner.
