Native Android Build, it will not building when this Plugin added:

Used Android Build Template from Corona-3723

build.gradle.kts:

plugins {
    id("com.android.application")
    id("com.google.gms.google-services")  // ← This causes the issue
}

Task :app:mergeDebugAssets FAILED
AGPBI: {"kind":"error","text":"Duplicate resources","sources":[...]}

Fixed File Example:

// ============================================================================
// GOOGLE-SERVICES PLUGIN FIX - DUPLICATE RESOURCES WORKAROUND
// ============================================================================
//
// PROBLEM: The google-services plugin causes "Duplicate resources" build errors
// when integrated with Solar2D/Corona SDK Native Android builds.
//
// ROOT CAUSE: The google-services plugin scans all registered asset directories
// during its processing phase. Since Solar2D registers the Corona assets directory
// using srcDirs(), it gets registered twice, causing duplicate resource errors.
//
// CHANGES MADE TO FIX THIS ISSUE:
//
// 1. LINE ~264 - coronaAssetsCopySpec() function:
// Added excludes for iOS-specific files that shouldn't be in Android builds:
// - Icon.png (iOS App Icon)
// - Images.xcassets/** (iOS App Icons)
// - LaunchScreen.storyboardc/** (iOS Launch Screen)
// - google-services.json (processed by google-services plugin)
//
// 2. LINE ~351-364 - android.applicationVariants.all block:
// CRITICAL CHANGES:
// a) REMOVED: android.sourceSets[name].assets.srcDirs(generatedAssetsDir)
// This line caused the duplicate registration with google-services plugin
//
// b) ADDED: doLast block in mergeAssetsProvider.configure
// Manually copies assets AFTER the merge process completes
// This prevents double-registration by google-services plugin
//
// c) ADDED: mustRunAfter for google-services task ordering
// Ensures google-services runs after Corona assets are ready
//
// RESULT:
// ✅ Build succeeds with google-services plugin enabled
// ✅ Firebase services work correctly
// ✅ No duplicate resource errors
// ✅ resource.car and all Corona assets properly included in APK
// ✅ App runs without crashes
//
// Compatible with:
// - com.google.gms.google-services
// - com.google.firebase.crashlytics
// - com.google.firebase.firebase-perf
// - All other Firebase plugins
//
// For more details, see Solar2D forum post about this fix.
