quarkus: Can't load static resource created by extension

Describe the bug

In my extension, I created a static resource with:

    @BuildStep
    public void processModel(BuildProducer<GeneratedResourceBuildItem> output,
            BuildProducer<AdditionalStaticResourceBuildItem> staticResources) {

        String path = "/routes.js";
        output.produce(new GeneratedResourceBuildItem("META-INF/resources" + path,
                "//hello".getBytes(StandardCharsets.UTF_8)));
        staticResources.produce(new AdditionalStaticResourceBuildItem(path, false));
}

When I try to test this:

@QuarkusTest
public class MyTest {
    @Test
    public void testJsRouting() {
        given()
                .when().get("/routes.js")
                .then()
                .statusCode(200)
                .body(is("//hello"));
    }
}

I’m getting the following exception:

ERROR: HTTP Request to /routes.js failed, error id: 0c1267fb-df47-4c0c-b97f-f7943ca4ef19-1

This is because those are served via a Vert.x StaticHandler, which accesses them via the file system, and obtains the URL to the resource via the QuarkusClassLoader: https://github.com/eclipse-vertx/vert.x/blob/master/src/main/java/io/vertx/core/file/impl/FileResolverImpl.java#L173 and then attempts to open it in https://github.com/eclipse-vertx/vert.x/blob/bbb4ddc417a604697d2ff4f5a8eda2e74113697e/src/main/java/io/vertx/core/file/impl/FileResolverImpl.java#L225

The problem is that QuarkusClassLoader serves it using a MemoryClassPathElement https://github.com/quarkusio/quarkus/blob/main/independent-projects/bootstrap/core/src/main/java/io/quarkus/bootstrap/classloading/MemoryClassPathElement.java#L86 that has a quarkus: URL scheme, which is registered via a UrlStreamHandler at https://github.com/quarkusio/quarkus/blob/main/independent-projects/bootstrap/core/src/main/java/io/quarkus/bootstrap/classloading/MemoryClassPathElement.java#L131 but Vert.x doesn’t know about it and doesn’t know how to deal with it.

I’m not sure what to do to fix this, frankly.

Well, OK, so I found how to write an extension test to have a special build step today:

package io.quarkus.vertx.http;

import java.nio.charset.StandardCharsets;
import java.util.function.Consumer;

import org.hamcrest.Matchers;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.RegisterExtension;

import io.quarkus.builder.BuildChainBuilder;
import io.quarkus.builder.BuildContext;
import io.quarkus.builder.BuildStep;
import io.quarkus.deployment.builditem.GeneratedResourceBuildItem;
import io.quarkus.test.QuarkusUnitTest;
import io.quarkus.vertx.http.deployment.spi.AdditionalStaticResourceBuildItem;
import io.restassured.RestAssured;

public class AdditionalStaticResourceTest {

    @RegisterExtension
    static final QuarkusUnitTest config = new QuarkusUnitTest()
            .addBuildChainCustomizer(buildCustomizer());

    static Consumer<BuildChainBuilder> buildCustomizer() {
        return new Consumer<BuildChainBuilder>() {
            @Override
            public void accept(BuildChainBuilder builder) {
                builder.addBuildStep(new BuildStep() {
                    @Override
                    public void execute(BuildContext context) {
                        String path = "/routes.js";
                        

                        context.produce(new GeneratedResourceBuildItem("META-INF/resources" + path,
                                "//hello".getBytes(StandardCharsets.UTF_8)));
                        context.produce(new AdditionalStaticResourceBuildItem(path, false));
                    }
                }).produces(GeneratedResourceBuildItem.class)
                .produces(AdditionalStaticResourceBuildItem.class)
                .build();
            }
        };
    }

    @Test
    public void testNonApplicationEndpointDirect() {
        RestAssured.given()
        .when().get("/routes.js")
        .then()
        .statusCode(200)
        .body(Matchers.is("//hello"));
    }
}

Here’s your reproducer 😉
