enunciate-maven-plugin failed to compile Java JSON client-side classes with generic type

[ChambreNoire]

Hi,

I'm updating a legacy project using java 8 and enunciate-maven-plugin version 2.13.0. I have updated to jdk 11 and enunciate-maven-plugin 2.15.1 and since this I have encountered problems.

                </executions>
            </plugin>
        </plugins>
    </build>

When the plugin is run by maven upon deploy, the following dto is not correctly compiled.

Any ideas ?

Many thanks in advance!

Looks like a bug in the java-json-client module. I'll look into it.

Can you share what your getters and setters look like for the profile property of the IdentityView class? Is it just something like:

public T getProfile() {
  ...
}

public void setProfile(T profile) {
  ...
}

[ChambreNoire]

@stoicflame yup that's exactly it, just basic getters & setters:

public T getProfile() {
    return this.profile;
}

public void setProfile(T profile) {
    this.profile = profile;
}

Thanks

I'm attempted to reproduce this, but everything seems to work for me.

Here's a diff I applied to enunciate-sample, can you tell me how to modify it to expose the problem?

No updates, closing this out. I'm happy to re-open as needed.
