Gradle plugin

The kotlinx.rpc library provides a Gradle plugin that applies the compiler-plugin artifacts and exposes the rpc extension. The extension covers compiler diagnostics, strict-mode reporting, and optional protoc-based code generation.

        plugins {
            kotlin("jvm") version "2.3.0"
            id("org.jetbrains.kotlinx.rpc.plugin") version "0.10.1"
        }
    

The plugin exposes the rpc extension:

        rpc {
            annotationTypeSafetyEnabled = true

            protoc {
                // gRPC / protobuf schema-first code generation
            }
        }
    

Top-level capabilities:

annotationTypeSafetyEnabled: Controls annotation type-safety checks. See Annotation type-safety.
strict: Configures strict-mode reporting for deprecated RPC patterns. See Strict mode.
protoc() / protoc { ... }: Enables Buf/protoc integration for schema-first protobuf and gRPC code generation. See Configuration.
