Walkthrough

This update modifies the WORKSPACE.bazel file to reference a newer version of the rules_java external dependency, updating both its URL and SHA256 checksum. Additionally, a minor whitespace adjustment is made in the _fail_with_attr function within antlr/repositories.bzl, with no impact on logic or functionality.

Poem

A hop and a skip, to Java anew,
With rules updated, dependencies grew.
A tiny space, in code aligned,
All neat and tidy, whitespace refined.
The rabbit approves, with whiskers a-twitch—
Onward to builds that go without a hitch! 🐇✨

Code Review

This PR updates rules_java to version 7.3.1 and includes a minor stylistic fix in antlr/repositories.bzl. The dependency update from 6.5.2 to 7.3.1 is a significant one.

To improve clarity for reviewers and future maintainers, could you please consider adding a brief note to the PR description? Linking to the rules_java 7.x release notes (e.g., 7.0.0 for major changes and 7.3.1 for this specific version) would be very helpful to highlight key changes, such as the default JDK version moving to 17 and the Bazel 6+ requirement.

Summary of Findings

  • rules_java Upgrade Implications: The update of rules_java to 7.3.1 brings significant changes, such as the default Java toolchain now being JDK 17 (previously JDK 11) and a requirement for Bazel 6.0.0+. Confirmation of testing and compatibility with these changes is recommended to ensure the project continues to build and function as expected.
  • Stylistic Improvement (Low Severity): A stylistic improvement was made in antlr/repositories.bzl (line 166) by adding an extra space before an inline comment (# type: ignore). This aligns with common style practices like PEP 8, which recommends two spaces before inline comments. This is a positive change for code readability. (Not commented on directly due to review severity settings focusing on medium+ issues).

Merge Readiness

This pull request updates a key dependency, rules_java, to a significantly newer version. While the code changes themselves are minimal, the implications of this upgrade (such as a new default JDK version and Bazel version requirements) are important to consider.

I recommend that the author confirm that the project has been thoroughly tested with rules_java 7.3.1 and that it is compatible with the new defaults and requirements. Adding details about this verification and linking to the rules_java release notes in the PR description would greatly benefit the review process and future maintainability.

As a reviewer, I am not authorized to approve pull requests. Given the medium severity concern raised regarding the implications of the dependency upgrade, I suggest these points be addressed or confirmed before this PR is merged.

Updating rules_java from 6.5.2 to 7.3.1 is a notable version jump. The 7.x series of rules_java introduces some important changes, including:

  • The default Java toolchain is now based on JDK 17 (previously JDK 11).
  • Bazel 6.0.0 or newer is required.

Could you confirm if:

  1. The project has been tested with these new defaults, particularly the implications of using JDK 17 by default?
  2. The Bazel version currently used by the project meets the new minimum requirement of 6.0.0+?

Understanding these aspects is crucial for ensuring a smooth upgrade. It might also be beneficial to explicitly state any necessary configuration changes or testing performed in the PR description.
