# Syntax: ./setup-worktree-gradle-wrapper.sh
#
# gradle/wrapper/gradle-wrapper.jar is listed in .gitignore -- it's not
# committed, by design (see gradle/init-gradle-wrapper.sh), to keep a binary
# out of version control. Every fresh checkout downloads and SHA-256-verifies
# it once. But `git worktree add` only checks out tracked files, so a freshly
# created linked worktree gets no gradle-wrapper.jar at all, and `./gradlew`
# fails immediately with "Unable to access jarfile .../gradle-wrapper.jar"
# until someone runs gradle/init-gradle-wrapper.sh (or copies the jar over
# by hand).
#
# Run this script from inside a linked worktree of this repo to fix that. If
# the main checkout already has a verified gradle-wrapper.jar for the same
# Gradle version, it's copied over directly (no network needed). Otherwise
# this falls back to gradle/init-gradle-wrapper.sh, which downloads and
# verifies the jar from Gradle's distribution service.
