Note: Before using this plugin, please note that there is no test coverage right now, but it will be done in near future.

What is gogradle

A Gradle plugin supports Go module/package build lifecycle, also integrate go modules started from Go 1.11 for dependency management.

Installation

}

Go Environment

gralde goenv, setup Go environment in .gogradle

gRPC Support

gralde godep, besides resolving package dependencies, setup environments for popular go frameworks (gRPC, gRPC gateway, Gin-Swagger)

gralde gogrpc, generate gRPC stubs from protobuf schemas and swagger files for gRPC gateway support

Swagger Support

gralde goswag, generate swagger files for Gin-Swagger support

Dependencies Management

gralde godep, resolve packages build/test dependencies in gogradle DSL, then create/update go.mod and download all dependent packages.

Test

gralde gotest, run testing, also support ignored folders and different coverage reports (json, xml). XML is Cobertura compatible.

Custom Go Task

import com.pivotstir.gogradle.tasks.Go

task myTask(type: Go) {
    go("help test", [:])
    go("help build", [:])
}
