Android Studio – Keystore password was incorrect

When I try to create signed bundle for my flutter app I get

Execution failed for task ':app:signReleaseBundle'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.FinalizeBundleTask$BundleToolRunnable
   > Failed to read key key0 from store "/Users/username/keystores": keystore password was incorrect

I have the correct password and I know this because I wrote it down. My password has only numbers and basic letters. When I run

./gradlew signingReport

I get

Variant: release
Config: release
Store: /Users/myname/keystores
Alias: key0
Error: Failed to read key key0 from store "/Users/myname/keystores": keystore password was incorrect

This same failure happened when I tried to use the keystore for the first time but then I was able to fix it by cleaning the android project. But now the cleaning does not work anymore.

Here is my app/build.gradle

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    compileSdkVersion 31

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        applicationId "myApplicationId"
        minSdkVersion 24
        targetSdkVersion 31
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }

    buildTypes {
        release {
            signingConfig signingConfigs.release
            shrinkResources false
            minifyEnabled false
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

Here is my local.properties

sdk.dir=/Users/myName/Library/Android/sdk
flutter.sdk=/users/myName/developer/flutter
flutter.buildMode=release
flutter.versionName=0.1.5
flutter.versionCode=6

I have tried:

• Cleaning and rebuilding the project
• Default passwords ("changeit", "android", "password", "")
• Removing build folder
• Reinstalling Flutter, Dart and Android studio
