Error generating classes from generateClientApi or generateClientApiV2
Error generating classes from generateClientApi or generateClientApiV2.
Constructors with invalid number of arguments.
schemas:
type Query {
shows: [Show]
}
type Show {
title: String,
id: String
}
I'm using graphqlcodegen-maven-plugin to generate the code. When I run mvn clean install the command generates the classes but with an error:
file: ShowsProjectionRoot.java
package com.graphql.engine.codegen.client;
import com.netflix.graphql.dgs.client.codegen.BaseSubProjectionNode;

@Generated(

@com.graphql.engine.codegen.Generated
public class ShowsProjectionRoot<PARENT extends BaseSubProjectionNode<?, ?>, ROOT extends BaseSubProjectionNode<?, ?>> extends BaseSubProjectionNode<PARENT, ROOT> {
public ShowsProjectionRoot() {
super(null, null, java.util.Optional.of("Show")); //current line with the error because the constructor only accepts two argument
}
public ShowsProjectionRoot<PARENT, ROOT> title() {
getFields().put("title", null);
return this;
}
public ShowsProjectionRoot<PARENT, ROOT> ano() {
getFields().put("ano", null);
return this;

}
this is error:

Hi @annarafaeladev. What version of the dgs-codegen are you using? The generateClientv2 configuration option was created to allow users to opt into the v2 API. It's still there for legacy reasons and as of v6.0.1, setting either generateClient or generateClientv2 to true will result in the v2 API being generated.
For your issue, in the latest version of the dgs-codegen gradle plugin v6.2.1, I am not able to replicate the errors with the schema provided. It may be related to the maven port, have you tried that community? That would be this github page

I noticed that the version you are using for the dgs BOM is bit outdated at v3.10.2. Right now latest is v8.6.1. Can you try upgrading to the latest version? I'm not sure if that will solve your issue but it might be a good start. Note that post v6.0.0 spring boot 3 is required.
its ok, so i updated dependencies for version 8.6.1 but the problem persist. I copied the pom.xml with dependencies correctly updated.

ERROR after update dependency version 8.6.1
package com.netflix.graphql.dgs.client.codegen does not exist cannot find symbol
error ocurrently in line 3
Per the docs here: https://netflix.github.io/dgs/generating-code-from-schema/#client-api-v2
You are missing an additional <> for the ProjectionRoot.
String query = new GraphQLQueryRequest(
new MoviesGraphQLQuery(),
new MoviesProjectionRoot<>().movieId()).serialize();
Sorry, I don't understand where I should add this code snippet since the classes MoviesGraphQLQuery and MoviesProjectionRoot are automatically generated by the codegen plugin inside the target folder.
Could you explain me?
And after modifying the plugin version, the codegen client import is giving a not found error
Ok, after lookingcloser, the error is in the generated classes. My guess is that somehow you are missing the com.netflix.graphql.dgs.codegen:graphql-dgs-codegen-shared-core in your deps which should be brought in by codegen. I am not familiar with your maven project set up, so would verify first whether you have that in your dependencies. I would also maybe try posting on the maven port project since there could be something missing there.
I added the mentioned dependency but the problem persists:
<dependency>
<groupId>com.netflix.graphql.dgs.codegen</groupId>

Hi @annarafaeladev - we don't support the maven port of codegen here. Please try https://github.com/deweyjose/graphqlcodegen for help with this issue.
