It happened out of nowhere. One day I was running my code which was working just fine, and the next day, without touching my build.gradle files or any other build files this error popped up.
I have tried a lot of different solutions like changing my buildToolsVersion or setting a specific flag of AAPT(can't remember which) to false. Nothing works. My app\build.gradle file:
android {
compileSdkVersion 27
buildToolsVersion '27.0.3'
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
// TODO: Specify your own unique Application ID
(https://developer.android.com/studio/build/application-id.html).
applicationId "com.skydevs.bookx"
minSdkVersion 16
targetSdkVersion 27
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner
"android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release`
works.
signingConfig signingConfigs.debug
}
}
}
flutter {
source '../..'
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-
core:3.0.2'
implementation 'com.google.firebase:firebase-core:16.0.1'
}
apply plugin: 'com.google.gms.google-services'
The error I'm getting is:
Execution failed for task ':app:processDebugResources'.

Today, I got the same error at my project which I was working on yesterday without any problem.
Some upgrade causes this error IMO, my solution is:
Open the project via Android Studio
Open android/build.gradle and android/app/build.gradle
Just correct things what IDE warns about, it usually warns your SDK, Kotlin and Gradle versions etc.
It's not mandatory but you can check your .bashrc exports or environment variables, sometimes it can fix some problems.
Edit: When you are updating your SDK versions, don't forget to upgrade also your project dependencies.
