Quarkus Classloader in Test not returning all results

[rdehuyss]

Describe the bug

Hi there, I'm Ronald and the creator of https://github.com/jobrunr/jobrunr.

I'm currently writing an extra test using @QuarkusTest and I'm loading resources from the classpath. My setup is Intellij / a multimodule Gradle project / Quarkus.

I'm using the following code:

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
Enumeration<URL> contextClassLoaderResources = classLoader.getResources(folder);
List<URL> result = Collections.list(classLoaderResources)

Currently, I only have the following result:
file:/Users/rdehuyss/Projects/JobRunr/jobrunr/core/build/classes/java/main/org/jobrunr/storage/sql/common/migrations

However, I also expected the following result:
file:/Users/rdehuyss/Projects/JobRunr/jobrunr/core/build/resources/main/org/jobrunr/storage/sql/common/migrations

From what I understand, the JavaDoc of getResources mentions:

Finds all the resources with the given name.

If I do

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL url = classLoader.getResource(folder + "/v000__create_migrations_table.sql")

then the url is available and the resource is found.

Any idea why the classloader.getResources(folder) is not returning the actual resources but only the java classes? Is this a bug in the Quarkus ClassLoader?

Expected behavior

Return all the resources on the classpath.

Actual behavior

Only returns first resource on the classath

How to Reproduce?

See https://github.com/rdehuyss/quarkus-classloader-reproducer.

The ClassLoaderTest in the module quarkus should succeed whereas it currently fails.
