#!/usr/bin/env bash
# Sync reference test-app/ to the E2E sibling copy, then npm install + cordova build (or run).
# Used by .af-e2e/test-plan.json build_cmd (CI + local) — default is **build** only, same as before.
#
# Usage (from plugin repo root):
#   ./scripts/e2e-cordova-build.sh android          # build APK only
#   ./scripts/e2e-cordova-build.sh android run      # build + install/launch on emulator
#   ./scripts/e2e-cordova-build.sh ios              # build .app for simulator only
#   ./scripts/e2e-cordova-build.sh ios run          # build + install/launch on simulator
#
# Env:
#   ENV_FILE                 Multiline `.env` body (DEV_KEY=, APP_ID=). CI: set from GitHub secret on
#                            this script’s environment (CI: GitHub secrets.ENV_FILE). Local: optional
#                            if `.af-e2e/.env.local` or `test-app/.env` exists — see scripts/write-e2e-env-to-dir.sh.
#   TEST_APP_E2E_COPY_DEST  Same as sync-test-app-e2e-copy.sh (must match .af-e2e paths if non-default)
#   CORDOVA_E2E_ANDROID_JAVA_HOME  If set, used as JAVA_HOME for Android builds only (overrides auto-pick).
#   CORDOVA_E2E_RESPECT_JAVA_HOME  If set to 1, do not change JAVA_HOME for Android (Gradle may still use
#                                  ~/.gradle/gradle.properties org.gradle.java.home unless you set GRADLE_OPTS).
#   CORDOVA_E2E_IOS_BUILDCONFIG    Optional path to Cordova build.json for iOS (default: build.json in E2E app root if present).
#   CORDOVA_IOS_POD_REPO_UPDATE    1 = refresh CocoaPods specs before iOS platform add/build (default: 1 in GitHub Actions, 0 locally).
