Java Format

Apply google-java-format (AOSP style, in place) to Java files: the changed files, the staged files, all files, or specific paths. It asks which google-java-format version to use (e.g. 1.7 or 1.32.0), resolves the jar (GJF_JAR, then $GJF_DIR if set, then a cache, else auto-downloads that version), and runs it. Use when you want to format Java code to the project style, before committing. Triggers on phrases like 'google-java-format 적용', '자바 코드 스타일 적용', '변경된 자바 포맷', 'format the java files', 'apply java formatting'.

Apply google-java-format

Format Java files with google-java-format in AOSP style, replaced in place (-a -r). Handles the four scopes: changed, staged, all, or explicit paths.

Step 1: Pick the version

Ask the user which google-java-format version to use (commonly 1.7 or 1.32.0) unless they already said it. Projects pin different versions to match their CI, so do not assume a default.

Step 2: Run

bash <skill-base-dir>/assets/format.sh --version <ver> <changed|staged|all|FILE...>

changed: working-tree changes (git diff --diff-filter=ACM -- '*.java')
staged: staged files (git diff --cached …)
all: every *.java under the current directory
or one or more file / directory paths

The helper resolves the jar in this order (no hardcoded personal path): GJF_JAR (explicit jar path) → $GJF_DIR/google-java-format-<ver>-all-deps.jar if GJF_DIR is set (point it at your local jar folder, e.g. export GJF_DIR="$HOME/Driver/google-java-format") → the cache ~/.cache/claude-skills/google-java-format/ → otherwise auto-download that version from GitHub releases into the cache. Needs java on PATH (and curl only if it has to download).

Step 3: Report

Say how many files were formatted. This edits files in place, so suggest reviewing git diff before staging. For the all scope on a large tree, confirm the scope with the user first (it can touch many files).

Notes: style is AOSP (4-space) via -a, matching your convention. To format a specific file, pass its path instead of a scope word.
