Hilla stopped generating endpoints in typescript

Question

I am using Hilla 2.3.2 and hilla-maven-plugin with spring.

Hilla stopped generating all typescript classes for my BrowserCallable endpoints and Records. I can't see any errors during the build process. Some vaadin files are copied/generated under Frontend/generated/ but nothing else.

I also went back to the last commit where the generator worked but still, no endpoint generation anymore.

Any help? E.g. is there some debug logging to be enabled? How does the Hilla maven plugin scan the classpath?

For reference, I am posting the "java-side" of the project as the code generation should happen with the maven plugin.

spring.devtools.restart.additional-exclude=dev/hilla/openapi.json
vaadin.whitelisted-packages = com.vaadin,org.vaadin,dev.hilla,com.test

Spring Application:

package com.test;

import com.vaadin.flow.component.page.AppShellConfigurator;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationPropertiesScan;

@ConfigurationPropertiesScan
public class TestApplication implements AppShellConfigurator {

    public static void main(String[] args) {
        SpringApplication.run(TestApplication.class, args);
    }

}

Controller Endpoint (expecting a generated TypeScript proxy):

package com.test;

import com.vaadin.flow.server.auth.AnonymousAllowed;
import dev.hilla.BrowserCallable;

import java.util.List;

@BrowserCallable
@AnonymousAllowed
public class TestController {

  public List<TestDTO> test() {
    return List.of(
        new TestDTO("a"),
        new TestDTO("b")
    );
  }

}

Record class (expecting a generated TypeScript model):

package com.test;

public record TestDTO(String id) {

}
