How do I change the output path for local EAS builds in Expo?

How can i change the path of EAS local builds?

Currently when i run a local EAS build, the build output is in the project root. I would like to define a custom path for the build output.

I have tried reading through the docs and the most promising is https://docs.expo.dev/build-reference/eas-json/. But it is still not 100% clear to me.

You can achieve this by using the --output flag.

Example - eas build -p ios --local --profile production --output "<CUSTOM_DIRECTORY>/<ipa|aab>"

Method 1.
Using a couple of env variables you can set it as below. This is from the doc:

EAS_LOCAL_BUILD_WORKINGDIR - Specify the working directory for the build process, by default it's somewhere (it's platform dependent) in /tmp folder.

EAS_LOCAL_BUILD_SKIP_CLEANUP=1 - Set this to disable cleaning up the working directory after the build process is finished.

Method 2.
It is mentioned in the --help that it can be done by adding the --output flag after the --local and specifying the output directory as below (showing other flags too).

eas build [-p android|ios|all] [-e <value>] [--local] [--output <value>] [--wait] [--clear-cache]
    [--auto-submit | --auto-submit-with-profile <value>] [-m <value>] [--json --non-interactive]

Note:
Method 1 takes precedence over Method 2, meaning if you set the env variable, Method 2 does not work.
