How Can I Redirect the Go Build Cache Directory?

Redirecting the Go Build Cache Directory

During the Go build process, certain dependencies are cached in the ~/.cache directory. However, this default location may be undesirable due to specific system requirements or concerns. To address this, Go provides a solution to alter the cache directory location.

Setting the $GOCACHE Environment Variable

The location of the Go build cache can be modified by setting the $GOCACHE environment variable. This variable specifies the desired path to the cache directory, allowing developers to choose a more appropriate storage location.

export GOCACHE=/my/custom/cache/directory

By setting the $GOCACHE environment variable before executing the Go build command, the cache will be redirected to the specified directory.

Note: The cache directory specified in $GOCACHE must exist and be writable by the current user. If the directory does not exist, the build process will fail with an error.
