io.vertx.core.spi.VerticleFactory: Provider io.vertx.lang.ceylon.CeylonVerticleFactory not a subtype

[Евгений Мартын]

Hi,

I have java maven project "launcher" :

package launcher;

import java.io.File;
import java.io.IOException;
import java.util.HashMap;

import io.vertx.core.DeploymentOptions;
import io.vertx.core.Vertx;
import io.vertx.core.VertxOptions;
import io.vertx.core.json.JsonObject;

public class Deployer {
   
    public static void deployVerticle(String verticle, HashMap<String,String> dOptions){
        System.out.println("start deployVerticle");
        try {
            File current = new File(".").getCanonicalFile();
            System.out.println(current.toString());    
            System.setProperty("vertx.cwd", current.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }

        // ClusterManager mgr = new HazelcastClusterManager();
        VertxOptions options = new VertxOptions().setClustered(true);// .setClusterManager(mgr);

        Vertx.clusteredVertx(options, res->{
            if (res.succeeded()) {
                Vertx vertx = res.result();
                try {
                   
                    JsonObject jObject = new JsonObject();
                    dOptions.forEach((key,value)->{
                        jObject.put(key, value);
                    });
                   
                    vertx.deployVerticle(
                            verticle,
                            new DeploymentOptions().setConfig(jObject)                            
                    );
                   
                } catch (Throwable t) {
                    t.printStackTrace();
                }
               
            } else {
                res.cause().printStackTrace();
            }
        });
        System.out.println("finish deployVerticle");
    }
   
    public static void main(String[] arg){
        deployVerticle("ceylon:ru.dellin.math.solver.gurobi.client.launcher/1.0.0",new HashMap<String,String>());
    }
}

</project>

and Ceylon project "test" with module "verticle":

native("jvm")
module verticle "1.0.0" {
    shared import io.vertx.ceylon.core "3.2.2";
    shared import launcher "1.0.0";
}

import java.lang {
    JString=String
}
import java.util {
    HashMap
}

import launcher {
    Deployer
}

"Run the module `verticle`."
shared void run(){    
}

shared void testRun() {
    HashMap<JString,JString> dOptions  = HashMap<JString,JString>();
   
    Deployer.deployVerticle(
        "ceylon:verticle/1.0.0",
        dOptions
    );
}

import io.vertx.ceylon.core {
    Verticle
}

shared class TestVerticle() extends Verticle() {
    shared actual void start(){
        print("-- TestVerticle --");
    }
}

When I run testRun() from module "verticle" everything is fine. But if I create other ceylon project "test2" with module "runner":

native("jvm")
module runner "1.0.0" {
    shared import verticle "1.0.0";
}

import verticle {
    testRun
}

"Run the module `runner`."
shared void run() {
    testRun();
}

and run run() from this module I get error:

what could it be?

Does anyone know what it means: Provider io.vertx.lang.ceylon.CeylonVerticleFactory not a subtype ?
