fix(cli): do not override GOOGLE_CLOUD_PROJECT in Cloud Shell when using Vertex AI by jackwotherspoon · Pull Request #24455 · google-gemini/gemini-cli

jackwotherspoon · 2026-04-01T19:04:35Z

Summary

Fixes an issue where GOOGLE_CLOUD_PROJECT was being incorrectly overridden to cloudshell-gca in Cloud Shell even when the user had explicitly selected Vertex AI authentication.

vertex.-.cloud.shell.mp4

Details

In Cloud Shell, the CLI normally overrides GOOGLE_CLOUD_PROJECT to a default value (cloudshell-gca) to avoid using the project set via gcloud. However, when using Vertex AI, users often intend to use a specific project. This change ensures that if selectedAuthType is vertex-ai, the override is skipped, respecting the existing environment or .env settings.

When in Cloud Shell, if a user switches to Vertex auth, it tells the user to restart to make sure the project gets picked up.

Fixes #24494

How to Validate

Simulate Cloud Shell environment (export CLOUD_SHELL=true).
Set a custom GOOGLE_CLOUD_PROJECT.
Run the CLI with Vertex AI auth type configured in settings.
Verify GOOGLE_CLOUD_PROJECT remains as set by the user/env.

Automated tests added in packages/cli/src/config/settings.test.ts.

…ing Vertex AI

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses an issue where the CLI's default behavior in Cloud Shell was overriding user-defined project settings. By introducing a check for the selected authentication type, the system now correctly respects user configurations when Vertex AI is in use, ensuring a more predictable environment setup.

Highlights

Environment Variable Override: Modified the CLI to prevent the automatic override of GOOGLE_CLOUD_PROJECT when running in Cloud Shell if the user has explicitly selected Vertex AI authentication.
Testing: Added a new test case in settings.test.ts to verify that the project environment variable is preserved when Vertex AI auth is configured.

Code Review

This pull request modifies the Cloud Shell environment setup to ensure that the GOOGLE_CLOUD_PROJECT environment variable is not overridden when the vertex-ai authentication type is selected. This change allows the CLI to respect the user's project configuration in Vertex AI environments. The update includes a new unit test to validate this logic. I have no feedback to provide.

Whoaa we seem to have amazing redesign and refactoring here love it , i looked at the diff changes seems like those went like major changes (i just looked at them)

I love the UX improvements and the refactors !

it seems like the old issue still persists, which is the restart dialog seems to linger after exiting the session, (i just ran the changes locally)

I personally feel like we can fix this bug with this PR itself !

Sweet, let me tackle the final piece here 👍 Thanks @JayadityaGit

JayadityaGit · 2026-04-09T15:00:30Z

one final note I am including this issue #24505 , this was triaged as p3 (i feel this is a sub part of this PR)

anyways thanks !

JayadityaGit · 2026-04-09T16:55:47Z

i apologise for not communicating this sooner., by default i actually use Alternate screen buffer mode, where with a successfull google sign in

restart dialog in the actual session clears off
but still lingers after exiting the cli (creating unecessary noise)

i just switched to normal mode to check if it make any difference, in this mode after successful sign in

restart dialog in the session still persists
also lingers after exiting the cli

I just wanted to communicate this, thanks for making the cli better 💚.

Howdy @jackwotherspoon this PR looks good and largely addresses two birds with one stone. LGTM.
