Quarkus native and org.kohsuke:github-api - Failed to deserialize exception

问题

I'm playing with Quarkus native and org.kohsuke:github-api:1.111 and I see Failed to deserialize exception in native mode when doing simple new GitHubBuilder().withOAuthToken(ghToken).build();. This works in JVM mode.

The main problem is probably the fact that org.kohsuke:github-api is not ready for native mode. I still want to ask if there are any options to workaround this, maybe some jackson tricks for https://github.com/github-api/github-api/blob/master/src/main/java/org/kohsuke/github/GHMyself.java (stacktrace contains Cannot construct instance of org.kohsuke.github.GHMyself (no Creators, like default construct, exist)).

Exception details:

Reproducer details:

generate the app - https://quarkus.io/guides/getting-started#bootstrapping-the-project

add dependencies and quarkus.native.enable-https-url-handler propery for native

    <dependency>
      <groupId>org.kohsuke</groupId>
      <artifactId>github-api</artifactId>
      <version>1.111</version>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-resteasy-jackson</artifactId>
    </dependency>
...
      <properties>
        <quarkus.package.type>native</quarkus.package.type>
        <quarkus.native.enable-https-url-handler>true</quarkus.native.enable-https-url-handler>
      </properties>

change GreetingResource

        GitHub github = new GitHubBuilder().withOAuthToken(ghToken).build();
        GHRepository ghRepo = github.getRepository("quarkusio/quarkus");
        return ghRepo.toString();

drop .body(is("hello")) from GreetingResourceTest

run mvn clean verify -Dnative

回答1:

You can also use @RegisterForReflection(targets = GHObject.class) on any of your classes

回答2:

My guess is that you will need to register all the GHObject hierarchy for reflection using a ReflectiveHierarchyBuildItem.

So that requires an extension. It would be a useful addition for the Platform IMHO.
