The CLIRR check is failing due to protobuf 4.x upgrade in the RC versions. Skipping clirr check for protobuf 4.x upgrade in this and next cycle. We should re-enable them once protobuf 4.x upgrade is completed.

Summary of Changes

Hello @blakeli0, 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 introduces a temporary modification to the build configuration by skipping the clirr API compatibility check. This adjustment is intended to streamline the ongoing upgrade process to Protobuf version 4.x, preventing potential build interruptions that might arise from clirr during this significant dependency update.

Highlights

  • Clirr Check Skipping: The clirr API compatibility check has been temporarily disabled in the gapic-generator-java-pom-parent/pom.xml by setting the clirr.skip property to true. This change is specifically made to facilitate the upgrade to Protobuf 4.x.

Code Review

This pull request disables the clirr binary compatibility check for all modules by setting <clirr.skip>true</clirr.skip> in the parent POM. While this is likely intended to unblock a Protobuf 4.x upgrade, it introduces a significant risk by disabling a key quality gate for the entire project. My review includes a comment recommending a more targeted approach by ignoring specific breakages, or at least adding a TODO to track the re-enabling of this check to mitigate the risk of unintentionally releasing breaking changes.

Globally disabling the clirr check with <clirr.skip>true</clirr.skip> is a significant risk, as it prevents the detection of any unintended binary incompatibilities across all modules, not just those related to the protobuf upgrade. This could allow breaking changes to be released accidentally.

The preferred and safer approach in this repository is to add specific, expected breakages to the clirr-ignored-differences.xml files. Was this approach considered?

If globally disabling the check is the only option, it should be treated as a temporary measure. Please add a TODO comment with a link to a tracking issue to ensure the check is re-enabled promptly.

This probably needs the check skip on showcase, like we tried last time.

Looks like the workflow file uses clirr:check directly. This may be overriding clirr.skip.
