Protocol buffers GRPC在从1.25.0更新到1.34.1后找不到simbol错误

如果我使用旧版本，Protobuf会成功地生成我的protos，但是当我将Protobuf依赖项更新到最新的1.34.1时，我总是面临这个问题

JavaLite运行时是。它包括生成的代码和运行时之间的接口。因此，您必须使用与protobuf javalite jar相同的protoc gen javalite版本（在本例中，可能是3.12.0）

我看到您正在使用protoc gen javalite版本3.0.0：

Java Lite代码生成作为一个内置组件与

protoc

合并在一起，因此不再使用插件语法

protobuf {
    protoc { artifact = 'com.google.protobuf:protoc:3.12.0' }
    plugins {
        grpc { artifact = 'io.grpc:protoc-gen-grpc-java:1.34.1' }
    }

    generateProtoTasks {
        all().each { task ->
            task.builtins{
                java { option 'lite' }
            }
            task.plugins {
                grpc { option 'lite' }
            }
        }
    }
}

非常感谢，您已经回答了我关于grpc的第二个问题！）
