Overview

build-info-go is a Go library, which allows generating build-info for a source code project. The library is also packaged as a CLI.

Read more about build-info and build integration in Artifactory here.

Using build-info-go as a CLI

Build the CLI from Sources

Make sure Go is installed.

Clone the sources:

git clone https://github.com/jfrog/build-info-go

CD to the root directory of the cloned project and build the sources as follows.

On Unix based systems run:

./buildscripts/build.sh

On Windows run:

.\buildscripts\build.bat

Once completed, you'll find the bi executable at the current directory.

Generating Build-Info

The Build-Info CLI allows generating build-info for your project easily and quickly.

All you need to do is to navigate to the project's root directory and run one of the following commands (depending on the package manager you use). The complete build-info will be sent to the stdout.

Go

bi go

Maven

bi mvn

Gradle

bi gradle

Logs

The default log level of the Build-Info CLI is INFO.

You can change the log level by setting the BUILD_INFO_LOG_LEVEL environment variable to either DEBUG, INFO, WARN or ERROR.

All log messages are sent to the stderr, to allow picking up the generated build-info, which is sent to the stdout.

Go APIs

Collecting and building build-info for your project is easier than ever using the BuildInfoService:

Creating a New Build

To use the APIs below, you need to create a new instance of BuildInfoService and then create a new Build (or get an existing one):

service := build.NewBuildInfoService()
bld, err := service.GetOrCreateBuild(buildName, buildNumber)

It's important to invoke this function at the very beginning of the build, so that the start time property in the build-info will be accurate.

Generating Build-Info

After you created a Build, you can create a new build-info module for your specific project type and collect its dependencies:

Go

// You can pass an empty string as an argument, if the root of the Go project is the working directory
goModule, err := bld.AddGoModule(goProjectPath)
// Calculate the dependencies used by this module, and store them in the module struct.
err = goModule.CalcDependencies()

// You can also add artifacts to that module:
artifact1 := entities.Artifact{Name: "v1.0.0.mod", Type: "mod", Checksum: &entities.Checksum{Sha1: "123", Md5: "456"}}
err = goModule.AddArtifacts(artifact1, artifact2, ...)

Maven

// You can pass an empty string as an argument, if the root of the Maven project is the working directory
mavenModule, err := bld.AddMavenModule(mavenProjectPath)
// Calculate the dependencies used by this module, and store them in the module struct.
err = mavenModule.CalcDependencies()

Gradle

// You can pass an empty string as an argument, if the root of the Gradle project is the working directory
gradleModule, err := bld.AddGradleModule(gradleProjectPath)
// Calculate the dependencies used by this module, and store them in the module struct.
err = gradleModule.CalcDependencies()

Collecting Environment Variables

Using CollectEnv() you can collect environment variables and attach them to the build.

After calling ToBuildInfo() (see below), you can also filter the environment variables using the IncludeEnv() and ExcludeEnv() methods of BuildInfo.

err := bld.CollectEnv()
buildInfo, err := bld.ToBuildInfo()
err = buildInfo.IncludeEnv("ENV_VAR", "JFROG_CLI_*")
err = buildInfo.ExcludeEnv("*password*", "*secret*", "*token*")

Get the Complete Build-Info

Using the ToBuildInfo() method you can create a complete BuildInfo struct with all the information collected:

buildInfo, err := bld.ToBuildInfo()
err = bld.Clean()

Clean the Build Cache

The process of generating build-info uses the local file system as a caching layer. This allows using this library by multiple processes.

If you finished working on a certain Build and you want to delete it from the cache, all you need to do is to call this function:

err := bld.Clean()

Tests

To run the tests, execute the following command from within the root directory of the project:

go test -v ./...
