Injection causes IllegalAccessError depending on archiveBaseName

[JanWiemer]

Describe the bug

I have a gradle multi-project with one Quarkus App (prj2) extending another (prj1).
(See also attached zipped reproducer project)

The settings.gradle file simply references the two sub-projects:

pluginManagement {
    repositories {
        mavenCentral()
        gradlePluginPortal()
        mavenLocal()
    }
    plugins {
        id "${quarkusPluginId}" version "${quarkusPluginVersion}"
    }
}
rootProject.name='project'
include 'prj1'
include 'prj2'

The gradle file of the root project is empty.
The sub-project 'prj1' simply depends on ARC:

plugins {
    id 'java'
    id 'io.quarkus'
}

repositories {
    mavenCentral()
    mavenLocal()
}

dependencies {
    implementation enforcedPlatform("${quarkusPlatformGroupId}:${quarkusPlatformArtifactId}:${quarkusPlatformVersion}")
    implementation 'io.quarkus:quarkus-arc'
}

The project prj1 simply contains one bean referencing a second one:

@Dependent
public class BaseBean {

  @Inject
  ReferencedBean refBean;

  public String getIdentity() {
    return "BaseBean (including reference to  " + refBean.getIdentity() + ")";
  }

}

@Dependent
public class ReferencedBean {

  public String getIdentity() {
    return "ReferencedBean";
  }

}

The sub-project 'prj2' depends on ARC and prj1 (and has a test):

plugins {
    id 'java'
    id 'io.quarkus'
}

repositories {
    mavenCentral()
    mavenLocal()
}

dependencies {
    implementation enforcedPlatform("${quarkusPlatformGroupId}:${quarkusPlatformArtifactId}:${quarkusPlatformVersion}")
    implementation 'io.quarkus:quarkus-arc'
    implementation project(':prj1')
    testImplementation("io.quarkus:quarkus-junit5") { exclude group: 'io.quarkus', module: 'quarkus-junit5-properties' }
}

This project contains a deviation of the base bean defined in prj1:

@Dependent
public class DerivedBean extends BaseBean {

  @Override
  public String getIdentity() {
    return "DerivedBean extending " + super.getIdentity();
  }

}

The following test in prj2 checks if the injection works as expected:

@QuarkusTest
public class BeanTest {

  @Inject
  DerivedBean bean;

  @Test
  void test() {
    System.out.println(bean.getIdentity());
  }

}

The test works as expected in this scenario.
However if I add the following lines changing the archive base name
in the gradle.build file in prj1 the test will fail:

jar {
    archiveBaseName = "${rootProject.name}-${project.name}"
}

The test faile with the following exception:

[Ladicek]

I rewrote the reproducer to Maven and the issue is gone. This suggests the problem lies in the Quarkus Gradle plugin.

[gsmet]

@Ladicek and you rewrote this part too:

jar {
    archiveBaseName = "${rootProject.name}-${project.name}"
}

?

[Ladicek]

I translated that to <build> / <finalName>. Maybe that's not the right way to do it, but feels fairly close to me.

[JanWiemer]

In our tests it seemed to fail for any archiveBaseName other that the default...
