📝 Walkthrough

Walkthrough

This pull request introduces configuration updates, refactors code for efficiency and maintainability, and modernizes several components. Changes include extending bash command permissions and adjusting dangerous-mode settings in the configuration file, adding a Gradle cache warm-up step to the build workflow, removing obsolete comments from the Travis CI configuration, and refactoring the Options and OptionsDoclet classes with improvements such as converting string concatenation to StringBuilder, making static fields immutable, replacing Scanner with String.lines(), correcting typos, and adjusting error handling and filtering logic.

Inline comments:
In @.claude/settings.json:
- Line 32: The shared config currently disables the dangerous-mode confirmation
by setting skipDangerousModePermissionPrompt to true; change this value back to
false (or remove the override) so the confirmation guard remains enabled for
multi-user repos, and ensure the setting key skipDangerousModePermissionPrompt
is updated accordingly in the .claude/settings.json entry to restore the prompt.
- Line 22: Replace the overly-broad permission string "Bash(xargs cat:*)" with
scoped permissions that prevent arbitrary stdin-driven file reads: remove the
wildcard form and either drop the Bash xargs cat entry entirely or replace it
with explicit Read(...) rules and/or a narrowly-scoped Bash entry such as
allowing xargs cat only for a specific whitelist of safe paths (i.e., use
explicit Read(...) permissions or a non-wildcard "Bash(xargs
cat:/allowed/path/*)" style entry instead of "Bash(xargs cat:*)"). Ensure the
original "Bash(xargs cat:*)" token is removed so stdin-driven arbitrary file
disclosure is not possible.

In @.github/workflows/gradle.yml:
- Around line 28-29: The warm-up step "Warm up Gradle cache" currently masks all
errors by redirecting stdout/stderr and only sleeping on failure with "./gradlew
spotlessCheck > /dev/null 2>&1 || (sleep 60 && true)"; change it to a bounded
retry that preserves diagnostics (do not discard stdout/stderr) and retries a
small number of times with delays before giving up, e.g. loop up to N attempts
running "./gradlew spotlessCheck" and on failure echo the attempt and error,
sleep between attempts, and exit non‑zero only after all attempts fail; update
the workflow step command so failures are visible in logs while still
non‑blocking on transient flakiness.

In `@build.gradle`:
- Line 8: Update the misleading comment about Spotless task wiring so it
accurately states that only spotlessCheck is hooked into the Gradle lifecycle
(the check task) and that spotlessApply is not run automatically and must be
invoked explicitly; locate the comment mentioning spotlessApply and
spotlessCheck and change its wording to reflect that spotlessCheck runs with
check while spotlessApply must be run manually.
