Cannot read resources from the native image

[georgiivanov9]

Hi ! I am trying to load resources run time. This seems to fail when doing it with native-image. I found this on my project when T.class.getClassLoader().getResource(fileName). I am using Java 17 , GraalVM graalvm-ce-java17-22.3.1, native-maven-plugin:0.9.19

But also I tried your example repo and it is not working also which is using getResourceAsStream(fileName)

To Reproduce

Use repo Execute: mvn -Pnative clean package (Also tried mvn -Pnative clean native:compile)

And it is failing [ERROR] Failed to execute goal org.graalvm.buildtools:native-maven-plugin:0.9.19:test (test-native) on project maven-app-with-tests: Execution of /home/joroivanov/FT/graalvm_samples/native-build-tools/samples/java-application-with-resources/target/native-tests --xml-output-dir /home/joroivanov/FT/graalvm_samples/native-build-tools/samples/java-application-with-resources/target/native-test-reports -Djunit.platform.listeners.uid.tracking.output.dir=/home/joroivanov/FT/graalvm_samples/native-build-tools/samples/java-application-with-resources/target/test-ids returned non-zero result ->

Even if I skip the tests , the image is build but when I start the image it is throwing an exception.

Expected behavior Hello, native! logged in the console.

System Info (please complete the following information):

• OS: [Debian 11]
• GraalVM Version [22.3.1]
• Java Version [17]
• Plugin version [native-maven-plugin:0.9.19]

Additional context Note: I have to change plugin version to 0.9.19 as 0.9.20-SNAPSHOT is not in maven repo.
