# FIX SCRIPT: Capacitor Auto-Generated Files for Plugin Development Projects
# =============================================================================
# 
# PURPOSE: This script fixes common issues in Capacitor plugin development
# projects where auto-generated files have incorrect paths or references.
#
# WHEN TO USE:
# - After running 'npx cap sync'
# - After running 'npx cap update'  
# - After running 'npx cap add android'
# - After any Capacitor CLI command that regenerates integration files
# - When you get build errors about missing files or incorrect paths
#
# WHAT IT DOES:
# 1. Fixes capacitor.build.gradle (missing cordova.variables.gradle)
# 2. Fixes capacitor.settings.gradle (incorrect plugin path in test-apps)
#
# FIX 1: capacitor.build.gradle
# THE PROBLEM:
# Capacitor generates this line in capacitor.build.gradle:
#   apply from: "../capacitor-cordova-android-plugins/cordova.variables.gradle"
# But plugin development projects don't have this file, causing:
#   "Could not read script '.../cordova.variables.gradle' as it does not exist"
#
# FIX 2: capacitor.settings.gradle (Test App)
# THE PROBLEM:
# Capacitor generates this path in test-apps:
#   project(':timesafari-daily-notification-plugin').projectDir = new File('../node_modules/@timesafari/daily-notification-plugin/android')
# But the plugin module is actually in android/plugin/, not android root, causing:
#   "No matching variant of project :timesafari-daily-notification-plugin was found"
#
