DGS代码生成插件: generateJava无法工作

Question

我正在尝试使用本指南https://netflix.github.io/dgs/generating-code-from-schema/从模式生成pojo文件。

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
    }
}

获取误差

我尝试了较早版本的插件，但这没有帮助

Answer 1

看起来你和ANTLR有类路径冲突。这很可能是由于另一个Gradle插件引入了另一个(可能更旧的)版本的ANTLR。简单的解决办法是重新排序您的插件，将codegen插件放在其他插件之前。希望其他插件能与新版本的ANTLR一起工作，但通常情况下是这样的。

Answer 2

我在其他使用gradle的项目中尝试过，它可以工作。
