Create a new project

If you plan to work on a project that does not require complex dependency management, consider creating the Go project (File | New | Project ). Otherwise, create the Go modules project or enable Go modules in your current project.

Without Go modules, you need to store your source code under the GOPATH directory (a Go workspace). Also, you cannot install multiple versions of the same dependency package since the go get command downloads the dependency package to the same directory.

Create a Go project

  1. Select File | New | Project.

  2. In the New Project page, select Go.

  3. 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. For more information about installing Go SDK, see Installing Go SDK.

  4. (Optional) Toggle the Index entire GOPATH checkbox:

    • Checkbox cleared: project files and vendored packages are indexed. Packages from GOPATH are not indexed. Might improve the overall performance.

    • Checkbox selected: packages from GOPATH and project files are indexed.

  5. Click Next, specify a project name and click Finish.

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

  1. Open settings by pressing Ctrl+Alt+S and navigate to GOPATH.

  2. Select the Index entire GOPATH checkbox.

    Index entire GOPATH

Download and install dependencies

  1. Click an unresolved dependency in the import section and press Alt+Enter.
