maven-resource-error

This project provides an example, for a failing quarkus builds, when using a custom resource directory with maven variables.

The project contains a custom resource directory with a file, which should be available after the build in target/my-custom-files

Until the quarkus plugin version 3.21.3 the resource filtering of custom resource directories worked as expected. Starting with 3.21.4, it ends with an error.

How to reproduce:

mvn clean package

when starting the first Quarkus Test it fails with the following exception:

java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
	[error]: Build step io.quarkus.deployment.steps.CompiledJavaVersionBuildStep#compiledJavaVersion threw an exception: java.io.UncheckedIOException: Failed to walk directory /${project.build.directory}/my-custom-files
	at io.quarkus.paths.PathTreeVisit.walk(PathTreeVisit.java:31)
	at io.quarkus.paths.OpenContainerPathTree.walk(OpenContainerPathTree.java:105)

	at io.quarkus.deployment.ExtensionLoader$3.execute(ExtensionLoader.java:856)
	at io.quarkus.builder.BuildContext.run(BuildContext.java:255)

Skipping the test, everything is built as expected. The custom files are available

mvn -DskipTests clean package

Also downgrading to the version 3.21.3 of the quarkus-maven-plugin works as expected. In the pom use the version 3.21.3 instead of the quarkus.platform.version. Afterwards the test do not fail.

mvn clean package
