Auto Scanning not finding service classes

[jmihalich]

Hi,

First my set up is: Java 17, Jetty 11, and Jersey 3.0.4, and jersey-hk2. This is about as bare bones of a setup as you can get right now. My project has 2 classes in it, a resource class that injects a service class, and the service class itself. No other DI frameworks (like spring or guice).

I'm not able to get auto scanning working in the latest jersey-hk2. The code is not finding my @service class, and thus the Injection code is failing to find an instance of the class.

I added the following dependency to my maven pom file:

org.glassfish.hk2 hk2-metadata-generator 3.0.3

That generates the META-INF/hk2-locator/default file with the correct class name and path in it. However, in the .war file that file is not in the root /META-INF folder. it winds up in /WEB-INF/classes/META-INF folder. I don't know if that is the correct location or not. I tried manually putting the hk2-locator/default in the root META-INF folder but that had no effect.

Anyway, in my Jersey resource class where i Inject the service class, the container cannot find an instance of it...meaning nothing ever scanned and/or found the class to create it.

TestService class:

`TestService class:

import org.jvnet.hk2.annotations.Service;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@service
public class TestService implements PostConstruct, PreDestroy
{
private static final Logger LOGGER = LoggerFactory.getLogger(TestService.class);

public TestService()
{
}

public String getValue()
{
    return "got value";
}

public void postConstruct()
{
    LOGGER.info("postConstruct");
}

public void preDestroy()
{
    LOGGER.info("preDestroy:");
}

}
`

The full stack trace when the injection fails is attached.

Am I doing something wrong? Or am I missing something?

Thanks,
Joe
