Hello @fjuma, 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 a minor code quality issue by fixing a typo in the Artifact.Builder class. The change removes a redundant assignment within the extensions method, which improves code clarity and correctness without altering the functional behavior of the builder.

Highlights

Code Review

This pull request correctly fixes a typo in the Artifact.Builder where a field was being assigned to itself twice. The change is good. I've added one suggestion to further improve the code by ensuring the extensions list is never null, which aligns with best practices and seems to be the convention in other parts of your codebase.


public Builder extensions(List<String> extensions) {
this.extensions = this.extensions = (extensions == null) ? null : List.copyOf(extensions);
this.extensions = (extensions == null) ? null : List.copyOf(extensions);

While the typo fix is correct, consider initializing extensions to an empty list instead of null when the input is null. This avoids potential NullPointerExceptions for consumers of the Artifact object and aligns with the general best practice of returning empty collections instead of nulls. It also appears to be consistent with how other parts of the codebase handle collections, based on the tests for the Task class.

Suggested change
this.extensions = (extensions == null) ? null : List.copyOf(extensions);
this.extensions = (extensions == null) ? List.of() : List.copyOf(extensions);

Going to ignore this one since we use null elsewhere too.
