使用 Kotlin DSL 配置 Protocol Buffers 0.9.x

Question

我已将 Android 项目上的协议缓冲区版本从 0.8.x 更新到 0.9.1，但遇到了 gradle 同步错误。我已按照文档从文件中删除了导入build.gradle.kts，并且收到如下错误。

这是以下代码build.gradle.kts：

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:21.0-rc-1"
    }
    generateProtoTasks {
        all().forEach { task ->
            task.plugins {
                create("java") {
                    option("lite")
                }
            }
        }
    }
}

这就是错误，它指向该create("java") {行 - 如何使用 Kotlin DSL 配置协议缓冲区？

我需要更改它，如下所示

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:21.0-rc-1"
    }
    generateProtoTasks {
        all().forEach { task ->
            task.builtins {
                create("java") {
                    option("lite")
                }
            }
        }
    }
}
