Go (GOPATH)

You might want to create this type of a project if you do not need a complex dependency management and ready to store all the project files under GOPATH.

Create a GOPATH project

By default, IntelliJ IDEA creates a project with Go modules integration. You can disable this option in settings. But ensure that you keep the necessary file structure and store your project under GOPATH. For more information about storing your code under GOPATH, see How to Write Go Code (with GOPATH) at go.dev.

Firstly, you need to create a default Go project with Go modules integrations but be sure to place your project under GOPATH.

Create a project with Go integration

Select File | New | New Project.
Alternatively, click New Project in the Welcome to IntelliJ IDEA dialog.
In the New Project dialog, select New Project from the list of available projects.
Ensure that Go is selected as a project language in the Language list.
In the GOROOT field, specify the location of your Go installation. Usually, the location is defined automatically.
To change or install a new version of Go SDK, click the Add SDK… button and select Local… to choose the Go SDK version on your hard drive, or select Download… to download Go SDK from the official repository.
(Optional) Select or clear the Enable vendoring support automatically checkbox.
Since Go 1.14 RC, the automatic vendoring mode became a built-in Go feature. For Go versions 1.14 RC and later, the Enable vendoring support automatically checkbox is disabled. For more information about vendoring, see Vendoring.
(Optional) In the Environment field, specify environment variables that you need for your project. For example, the GOPROXY environment variable. Read more about environment variables in the Environment variables section.
Click Create.

Secondly, disable Go modules integration.

Disable the Go modules integration

Press Control+Alt+S to open the IDE settings and select Languages & Frameworks | Go | Go Modules.
Clear the Enable Go modules integration checkbox.

Add and install dependencies

GOPATH stores your code base and all the files that are necessary for your development. Also, it includes packages that you download and install. When disabled, only project and vendored packages are indexed. It might improve the overall performance but makes it impossible to use packages from GOPATH.

If your project has external dependencies, you might want to enable entire GOPATH indexing. By default, indexing of entire GOPATH is disabled.

Enable entire GOPATH indexing

Open settings by pressing Control+Alt+S and navigate to Languages & Frameworks | Go | GOPATH.
Select the Index entire GOPATH checkbox.

Download and install dependencies

Click an unresolved dependency in the import section and press Alt+Enter.
Select go get -t <package>.

Installing Go SDK

Select a local copy of the Go SDK

Press Control+Alt+S to open the IDE settings and select Languages & Frameworks | Go | GOROOT.
Click the Add SDK button () and select Local….
In the file browser, navigate to the SDK version that is on your hard drive.
Click Open.

Download the Go SDK

Press Control+Alt+S to open the IDE settings and select Languages & Frameworks | Go | GOROOT.
Click the Add SDK button () and select Download….
From the Version list, select the SDK version.
In the Location field, specify the path for the SDK. To use a file browser, click the Browse icon ().
Click OK.
