Qute: "No template found for path ..." only in Eclipse IDE

[mailq]

Describe the bug

When I run a Quarkus app from within Eclipse, I get an io.quarkus.qute.TemplateException that the specified template can not be found.
On the other hand, if I run ./gradlew quarkusDev from the command line, it works perfectly. Also when I build the app and then run the compiled quarkus-app.jar

Expected behavior

Quarkus (or Eclipse) should find the existing template in src/main/resources/templates.

Actual behavior

A "io.quarkus.qute.TemplateException: No template found for path ..." exception is thrown.

How to Reproduce?

I created a minimal project here https://github.com/mailq/qutebug

Run it as Java Application from within the Eclipse IDE (2021-12) and experience the exception.

Run it with ./gradlew quarkusDev at the command prompt and you get the correct output from the rendered template.
