Error when running plugin

[magx2]

Hey,

I took you plugin configuration from quick start and run the mvn compile phase. Sadly I'm getting and error: Cannot invoke "java.lang.Class.isAssignableFrom(java.lang.Class)" because "superClass" is null

Class that has implementation for endpoint:

@Slf4j
@RestController
@RequiredArgsConstructor
public class Foo implements Boo {

  @Override
  public ResponseEntity<Collection<AppInfo>> getDeployedApplications(ILoginName loginName) {
    // ...
  }

}

Interface:

@RequestMapping(API_PREFIX)
public interface Boo {

  String API_PREFIX = "/api";

  // @RequestBody ILoginName loginName
  @PreAuthorize("isAuthenticated()")
  @PostMapping(path = "/available-applications")
  ResponseEntity<Collection<AppInfo>> getDeployedApplications(
      @RequestBody ILoginName loginName);

}

Hello @magx2 , than you for your bug report.

I was not able to reproduce the bug with the given informations. Could you create a minimal project containing the error + host it on github to help me fix your problem?

I would also like to know which version of java is executing maven (available with "mvn --version").

Kind regards, Kevin

[magx2]

I'm using Java 17 + Maven 3.9.4

[kbuntrock]

Nothing suspicious about theses versions. To guide you, I suspect the bug is related to the structure of the "AppInfo" or "ILoginName" classes. Maybe you can give me more informations about them before creating a minimal project?

Kind regards, Kevin

Yes, le configuration looks normal. I meant informations about those two classes used as input and output in your webservice :

• AppInfo
• ILoginName

[magx2]

public interface AppInfo {

  IApplicationName getApplicationName();

  Collection<FleetNameIdentifiers> getAvailableFleets();
}

public interface ILoginName extends IName {
}

public interface IName {
    String getValue();
}

Hello @magx2.

It was still not enough information to enable me to reproduce your bug over the weekend. I'll need a sample project with the bug to help my investigation.

Wish you a nice day.

Kind regards, Kevin

[magx2]

Let me try to build something tommorow

Got it! The problem is with generics (extending and more generics...).

PS. Do not think to much about the model. It does not make sense (in this project). In my project it makes more sense 😁

[kbuntrock]

Perfect, I confirm you that I can reproduce the bug now. :)

Starting to think how to handle properly this problem, I keep you updated.

[kbuntrock]

Fixed, TU is done, and I tested the new version on your demo project.

I will make a new release in the following days as I want to integrate some small evolutions into v0.0.16.

[magx2]

Ok. Waiting for new version. Please do not wait too long cause I needto use it in my company project 😁

Pinky swear! ;) if tomorrow evening I see that I take more than an evening to code what I'm planning to add : I'll ship the version as it is.

[kbuntrock]

@magx2 : Version 0.0.16 is alive and available in Maven Central. :)

[magx2]

Works 🎉. Thanks!
