Building a Go Project

What This Guide Covers #

For Language versions and other build-environment specific information visit our reference pages:

The rest of this guide covers configuring Go projects in Travis CI. If you’re new to Travis CI please read our Tutorial and build configuration guides first.

Specifying a Go version to use #

You can use any tagged version of Go, a version with x in place of the minor or patch level to use the latest for a given major or minor version, or use master to get the latest version from source. All go version management is handled by gimme.

language: go

- 1.x
- "1.10"
- 1.11.x
- master

Go Modules #

Any value set for GO111MODULE via .travis.yml or repository settings is left as-is. If absent, a default value of GO111MODULE=auto is set.

Go Import Path #

The project source code will be placed in GOPATH/src/{repo-source}, but if vanity imports are necessary (especially for internal package imports), go_import_path: may be specified at the top level of the config, e.g.:


Dependency Management #

The default install step of travis_install_go_dependencies <go-version> [gobuild-args] will behave differently depending on the Go version specified, as well as the presence of certain environment variables and file paths.

If a Makefile is present by any of the following names, then no further actions are taken in the install step:

  • GNUMakefile
  • Makefile
  • BSDmakefile
  • makefile

In all other cases, the command go get ${gobuild_args} ./... is run.

godep support #

There is support included for godep when used with vendored dependencies such that the GOPATH will be prefixed with ${TRAVIS_BUILD_DIR}/Godeps/_workspace and PATH will be prefixed with ${TRAVIS_BUILD_DIR}/Godeps/_workspace/bin. Additionally, if the Godeps/_workspace/src directory does not exist,godep will be installed and a godep restore will be run.

It is important to note that using the older style Godeps.json at the top level is not supported.

All of the godep integration steps are performed prior to the separate go get and makefile steps listed above.

Note that the godep support is only activated if a custom install step is not specified.

Installing Private Dependencies #

As go get uses HTTPS to clone dependencies from GitHub rather than SSH, it requires a different workaround from our recommended way of handling private dependencies.

When cloning via HTTPS, git uses curl under the covers, which in turn allows you to specify a .netrc file, where you can store custom authentication credentials for specific domains, for instance.

Go to your GitHub account and create a personal access token.

Make sure to give it the repo scope, which allows accessing private repositories.

To reduce access rights of the token, you can also create a separate user account with access to only the repositories you need for a particular project.

Copy the token and store it in a .netrc in your repository, with the following data:

  login <username>
  password <token>

Add this to your repository and add the following steps to your .travis.yml:

- cp .netrc ~/.netrc
- chmod 600 ~/.netrc

Default Build Script #

Go projects assume that either Make or Go build tool are used by default. In case there is a Makefile in the repository root, the default command Travis CI will use to run your project test suite is


In case there is no Makefile, it will be

go test ${gobuild_args} ./...


These default commands can be overridden as described in the general build configuration guide. For example, to add the -v flag, override the script: key in .travis.yml like this:

script: go test -v ./...

The arguments passed to the default go test command may be overridden by specifying gobuild_args: at the top level of the config, e.g.:

gobuild_args: -x -ldflags "-X main.VersionString v1.2.3"

which will result in the script step being:

go test -x -ldflags "-X main.VersionString v1.2.3" ./...

To build by running Scons without arguments, use this:

script: scons

Environment Variable #

The version of Go a job is using is available as:


This may contain .x at the end, as described above. Use of this variable in the deployment condition should take this possibility into consideration. For example:

  - 1.7.x

    condition: $TRAVIS_GO_VERSION =~ ^1\.7
