How to Redirect the ~/.cache Directory During Go Build?

Redirection of ~/.cache Directory During Go Build

The Go build process utilizes the ~/.cache directory, which can be problematic in certain scenarios. This article addresses how to modify the location of this directory to suit your requirements.

Solution

The $GOCACHE environment variable allows you to specify an alternate location for the cache directory. By setting this variable before running the Go build command, you can redirect the cache to the desired directory.

Example

To redirect the cache to a directory named "/tmp/gocache," use the following command:

$ export GOCACHE=/tmp/gocache

Once the environment variable is set, subsequent Go builds will use the specified directory for caching.

Rationale

By default, the cache is located in the ~/.cache directory as defined by the operating system. However, this default location may not be suitable in all cases. For example, you may want to store the cache on a different drive or use a directory with more space. By modifying the $GOCACHE variable, you gain control over the cache's location.
