I am trying generate pojo files from schema using this guide https://netflix.github.io/dgs/generating-code-from-schema/

build.gradle.kts

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation(project(":graphql-dgs-spring-boot-starter"))
    implementation(project(":graphql-dgs-subscriptions-websockets-autoconfigure"))
    implementation("io.projectreactor:reactor-core:3.4.0")

    api("com.graphql-java:graphql-java:${Versions.GRAPHQL_JAVA}") //v 16.2
}

// Using plugins DSL
plugins {
    id("com.netflix.dgs.codegen") version "4.4.1"
}

tasks {
    generateJava {
//        schemaPaths = ["${projectDir}/src/main/resources/schema"] // List of directories containing schema files
        packageName ="com.example.packagename" // The package name to use to generate sources
        generateClient = true // Enable generating the type safe query API
    }
}

Getting error

I tried older versions of plugin, but that didn't help

It looks like you have a classpath conflict with ANTLR. This is very likely caused by another Gradle plugin that pulls in another (probably older) version of ANTLR. The easy workaround is to re-order your plugins, putting the codegen plugin before the other plugin. Hopefully, the other plugin works with the newer version of ANTLR, but usually, that is the case.

I tried in other project that use gradle, and it works.
