GO-GET(1)

NAME
go-get - add dependencies to current module and install them

SYNOPSIS
go get [-t] [-u] [-tool] [build flags] [packages]

DESCRIPTION
Get resolves its command-line arguments to packages at specific module versions, updates go.mod to require those versions, and downloads source code into the module cache.

To add a dependency for a package or upgrade it to its latest version:

    go get example.com/pkg

To upgrade or downgrade a package to a specific version:

    go get example.com/pkg@v1.2.3

To remove a dependency on a module and downgrade modules that require it:

    go get example.com/mod@none

To upgrade the minimum required Go version to the latest released Go version:

    go get go@latest

To upgrade the Go toolchain to the latest patch release of the current Go toolchain:

    go get toolchain@patch

See https://golang.org/ref/mod#go-get for details.

In earlier versions of Go, `go get' was used to build and install packages. Now, `go get' is dedicated to adjusting dependencies in go.mod. `go install' may be used to build and install commands instead. When a version is specified, `go install' runs in module-aware mode and ignores the go.mod file in the current directory. For example:

        go install example.com/pkg@v1.2.3
        go install example.com/pkg@latest

See `go help install' or https://golang.org/ref/mod#go-install for details.

`go get' accepts the following flags.

The -t flag instructs get to consider modules needed to build tests of packages specified on the command line.

The -u flag instructs get to update modules providing dependencies of packages named on the command line to use newer minor or patch releases when available.

The -u=patch flag (not -u patch) also instructs get to update dependencies, but changes the default to select patch releases.

When the -t and -u flags are used together, get will update test dependencies as well.

The -tool flag instructs go to add a matching tool line to go.mod for each listed package. If -tool is used with @none, the line will be removed.

The -x flag prints commands as they are executed. This is useful for debugging version control commands when a module is downloaded directly from a repository.

For more about build flags, see `go help build'.
