Description

I've created a simple application using

https://start.spring.io/#!type=maven-project&language=java&platformVersion=3.3.0&packaging=jar&jvmVersion=21&groupId=com.example&artifactId=demo-simple-obeservability&name=demo-simple-obeservability&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo-simple-obeservability&dependencies=actuator,web,modulith,native

I had to manually change

<spring-modulith.version>1.2.0-RC1</spring-modulith.version>

to

<spring-modulith.version>1.2.0</spring-modulith.version>

after executing

./mvnw clean install -Pnative native:compile
./target/demo-simple-obeservability

I got the following

then I've tried mitigating the issue as far as I could by adding

import com.tngtech.archunit.core.importer.ModuleImportPlugin;

@SpringBootApplication
@RegisterReflectionForBinding({ModuleImportPlugin.class})
public class DemoApplication {

and in pom.xml

        <dependency>
            <groupId>org.springframework.modulith</groupId>
            <artifactId>spring-modulith-observability</artifactId>
<!--            <scope>runtime</scope> -->
        </dependency>
.....
			<plugin>
				<groupId>org.graalvm.buildtools</groupId>
				<artifactId>native-maven-plugin</artifactId>
                                 <configuration>
                                       <buildArgs>
                                             <buildArg>--enable-url-protocols=jrt</buildArg>
                                       </buildArgs>
                                 </configuration>
			</plugin>

now the stacktrace is

Research direction

Reproduce the failure with the shown Maven native build and target command, then start at SpringModulithRuntimeAutoConfiguration and ModuleTracingBeanPostProcessor in the stack trace. Investigate the GraalVM failure to load ArchUnit's ModuleImportPlugin; done means the observability-enabled native application starts without this ClassNotFoundException.
