Gradle multi-module project causes quarkusDev to fail

[kdubb]

Describe the bug

The issue manifests itself differently between Java and Kotlin projects but the setup is the same, a multi-module Gradle project where one module depends on one or more other modules and any of the depended on modules have empty sources.

Running quarkusDev in a Kotlin project causes it to fail with gradle outputting Failed to run. If you run with --stacktrace you can see a further error Failed to locate classes directory in the project.

For Java, quarkusDev executes without error but Quarkus startup fails with a rather long chain of exceptions like Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: java.io.UncheckedIOException: Error while reading file as JAR: /Users/kdubb/Downloads/code-with-quarkus/modA/build/classes/java/main

This setup may seem unnecessary but we have some modules that are effectively dependency containers. One of the modules previously had some shared code and when that shared code was removed we encountered this issue; determining the cause of the issue was pretty time consuming.

Expected behavior

quarkusDev completes correctly in both Java & Kotlin projects with this configuration and that Quarkus starts up correctly in the same configuration.

Actual behavior

For Kotlin projects, quarkusDev fails with nondescript Failed to run error.

For Java projects, quarkusDev completes but Quarkus fails to start with Error while reading file as JAR.

To Reproduce

Attached are reproducer projects for both Java & Kotlin. The projects were derived from a simple code start project and adapted to use a shared gradle config in a way that many multi-module projects are setup

code-with-quarkus-kotlin.zip
code-with-quarkus-java.zip

To solve the issues in either project you just need to place a dummy.kt or dummy.java in the appropriate source directory for modA module.

Steps to reproduce the behavior:

1. Run quarkusDev in modB directory.

This may be related to #10894 as it seems to have an auspicious conclusion.

@kdubb thanks for reporting this I will have a look on both issue.

is this issue has been fixed ?
