what's the kind of a Class that with annotations @ProxyGen but without @VertxGen

[okou19900722]

@ProxyGen
public interface Test {
    @Fluent
    Test foo();
}

this method will add to anyJavaTypeMethods because of the kind of Test is ClassKind.OTHER

[okou19900722]

it throw that "error: TestVertxEBProxy is not abstract and does not override abstract method foo() in Test"

[vietj]

I think that interfaces with @ProxyGen and without @VertxGen should be rejected

Sorry for bumping, but in my project (using vertx 3.5.4) I had this working and in the generated proxy it contained the proxy methods, but now that we upgraded to 3.6.0CR1 (for a fix we required) I am indeed getting incomplete classes (same error that @okou19900722 stated).

I was always under the impression that I don't need VertxGen unless I want stub services generated, but I tried it anways alongisde ProxyGen but then getting this error:

Error:(20, 1) java: Could not generate model for com.our.package.EBOurService: [Error: could not create constructor: null]
  [Near : {... var futMethod = new io.vertx.codegen.MethodInfo( ....}]
               ^
  [Line: 1, Column: 798]

In fact, the service generates OK with VertxGen, but I still get the error, thus the complete build fails.

What am I missing? An example service that's failing to generate:

import io.vertx.codegen.annotations.Fluent;
import io.vertx.codegen.annotations.GenIgnore;
import io.vertx.codegen.annotations.ProxyGen;
import io.vertx.codegen.annotations.VertxGen;
import io.vertx.core.AsyncResult;
import io.vertx.core.Handler;
import io.vertx.core.Vertx;
import io.vertx.core.eventbus.DeliveryOptions;

@ProxyGen
@VertxGen
interface EBCluster1Service {
    String ADDRESS = "api.service.cluster1";
    String NAME = "cluster1";

    @GenIgnore
    static EBCluster1Service create(Cluster1Service delegate) {
        return new EBCluster1ServiceImpl(delegate);
    }

    @GenIgnore
    static EBCluster1Service createProxy(Vertx vertx, DeliveryOptions deliveryOptions) {
        return new EBCluster1ServiceVertxEBProxy(vertx, EBCluster1Service.ADDRESS, deliveryOptions);
    }

    @Fluent
    EBCluster1Service pong(String message, Handler<AsyncResult<String>> handler);
}

Me too. My interface is more or less the same. I'm using 3.6.0 release version.

EodService.java:[17,8] Could not generate model for com.diabolicallabs.quant.eoddata.EodService: [Error: could not create constructor: null]
[Near : {... var futMethod = new io.vertx.codegen.MethodInfo( ....}]

Removing @VetxGen seems to fix it but then I can't generate clients for non-Java languages.

[vietj]

can you provide a reproducer project @diabolicallabs ?

[diabolicallabs]

Working on it...

[vietj]

thanks

[diabolicallabs]

In creating the reproducer, I found the problem. I had a maven dependency with a transitive dependency on an older version of vertx-rx-java 3.2.1. Updating that solved the problem.

Here is the reproducer if you're interested: https://github.com/diabolicallabs/codegen-reproducer

Thank you for your interest Julien.

I'm getting

is that what you have too ?

[vietj]

it is weird because we are not using anymore MVEL and that is MVEL templating....

[vietj]

the problem is that you have code depending on old vertx versions:

[vietj]

this load the vertx 3.2.1 generators which are executed

changing the dep to:

            <groupId>com.diabolicallabs</groupId>
            <artifactId>vertx-cron</artifactId>

                <exclusion>

        </dependency>

builds fine for me
