## What it is
A Gradle plugin from Google that compiles Protocol Buffer (.proto) definition files by invoking protoc and wiring the generated Java/Kotlin sources into the project's compilation units. It supports both Java and Android Gradle projects.

## Use cases
- compile .proto files in a Gradle build
- generate Java classes from protobuf definitions
- set up protobuf codegen for an Android project
- integrate protoc into Gradle source sets
- build gRPC services with generated stubs in Gradle

## When to choose
- your JVM or Android Gradle project uses Protocol Buffers
- you want automatic protoc invocation and generated-source wiring
- you need per-sourceSet or per-variant proto compilation

## When to avoid
- your project does not use Gradle (e.g., Maven or Bazel)
- you generate only non-Java/Kotlin sources and need custom wiring anyway
- you need protobuf support outside the JVM ecosystem
