chore: fix broken integ tests after yarn berry migration#1343
Conversation
Add `yarn install --immutable-cache` after the version bump step. The bump changes workspace package versions, which requires the lockfile to be updated. Using `--immutable-cache` allows the lockfile to update while preventing new packages from being fetched from the registry.

Since the Yarn Berry migration, the integ test workflow fails during the build step because the version bump changes workspace package versions, which invalidates the
yarn.lockfile. The initialyarn install --immutablecorrectly ensures a clean lockfile on checkout, but afteryarn projen run bumpmodifies the workspace versions, the lockfile is now out of date and subsequent operations fail.This adds a
yarn install --immutable-cachestep between the bump and build steps. The--immutable-cacheflag allows the lockfile to be rewritten to reflect the new workspace resolutions, while still preventing any new packages from being downloaded from the npm registry. This gives us the safety guarantee we want (no surprise dependency changes) while accommodating the version bump.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license
