# FIX SCRIPT: capacitor.build.gradle for Plugin Development Projects
# =============================================================================
# 
# PURPOSE: This script fixes a common issue in Capacitor plugin development
# projects where the auto-generated capacitor.build.gradle file tries to load
# a file that doesn't exist, causing build failures.
#
# 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 cordova.variables.gradle
#
# WHAT IT DOES:
# - Finds the problematic line in capacitor.build.gradle
# - Comments it out with an explanatory comment
# - Prevents build failures in plugin development projects
#
# 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"
#
# THE FIX:
# Comments out the problematic line and adds explanation:
#   // Plugin development project - no Capacitor integration files needed
#   // apply from: "../capacitor-cordova-android-plugins/cordova.variables.gradle"
#
