Unable to run QuarkusTests in Eclipse since Quarkus 3.22

[manofthepeace]

Describe the bug

In Eclipse IDE, Right click on a file Run As-> Junit fails with the followiing;

java.lang.RuntimeException: Internal error. The test class class org.acme.GreetingResourceTest should have been loaded with a QuarkusClassLoader, but instead it was loaded with jdk.internal.loader.ClassLoaders$AppClassLoader@63c12fb0. This is caused by the FacadeClassLoader not correctly identifying this class as a QuarkusTest.
	at io.quarkus.test.junit.QuarkusTestExtension.getClassLoaderFromTestClass(QuarkusTestExtension.java:337)
	at io.quarkus.test.junit.QuarkusTestExtension.ensureStarted(QuarkusTestExtension.java:631)
	at io.quarkus.test.junit.QuarkusTestExtension.beforeAll(QuarkusTestExtension.java:712)
	at java.base/java.util.ArrayList.forEach(ArrayList.java:1596)

Runnin a single test from a @QuarkuTest works

Expected behavior

Running a full file works

Actual behavior

Exceptions happens

How to Reproduce?

reproduder: code.quarkus.io and download the default project

Steps to reproduce

Thanks for the report! Will have a look. It's interesting (and unexpected) that it works for single tests, but not whole files.

@gsmet, @mkouba have you guys by any chance noticed this?

If I do run as on the org.acme package I get this:

so normal test passes, but IT fails with

java.lang.IllegalStateException: Unable to locate the artifact metadata file created that must be created by Quarkus in order to run integration tests. Make sure this test is run after the Quarkus artifact is built from your build tool.
	at io.quarkus.test.junit.IntegrationTestUtil.readQuarkusArtifactProperties(IntegrationTestUtil.java:409)
	at io.quarkus.test.junit.QuarkusIntegrationTestExtension.ensureStarted(QuarkusIntegrationTestExtension.java:141)
	at io.quarkus.test.junit.QuarkusIntegrationTestExtension.beforeAll(QuarkusIntegrationTestExtension.java:127)
	at java.base/java.util.ArrayList.forEach(ArrayList.java:1511)

if I run the test from the .java file it has same error.

But if I run the greetingtest (non IT) individually I get:

java.lang.RuntimeException: Internal error. The test class class org.acme.GreetingResourceTest should have been loaded with a QuarkusClassLoader, but instead it was loaded with jdk.internal.loader.ClassLoaders$AppClassLoader@251a69d7. This is caused by the FacadeClassLoader not correctly identifying this class as a QuarkusTest.
	at io.quarkus.test.junit.QuarkusTestExtension.getClassLoaderFromTestClass(QuarkusTestExtension.java:337)
	at io.quarkus.test.junit.QuarkusTestExtension.ensureStarted(QuarkusTestExtension.java:631)
	at io.quarkus.test.junit.QuarkusTestExtension.beforeAll(QuarkusTestExtension.java:712)
	at java.base/java.util.ArrayList.forEach(ArrayList.java:1511)

so for me it does NOT work when running individually - but tests does work when I run per package, but not when IT.

[maxandersen]

can confirm running single method or via package normal test works - IT fails always.

if I run the suite class it fails.

[maxandersen]

and can also confirm if i downgrade to 3.20 then test class works no matter what but IT class fails for same reasons as in 3.22 so i Ireckon that is not a new issue.

[holly-cummins]

Ah, I had a feeling the IT issue might have been there before, but I didn't want to say until I checked! I've raised #47661 for the IT case.
