Flutter Picking Wrong Keystore path and giving error key.jks not found

I followed all the steps on the Flutter official site and thought I'd done everything correctly but it is failing to locate the keystore file when I build it.

This is the error message I get showing it taking wrong path instead of D:\flutterapps\testapp\key.jks:

PS D:\flutterapps\testapp> flutter build apk
Initializing gradle...                                       1.3s
Resolving dependencies...                                    4.3s
Gradle task 'assembleRelease'...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:validateSigningRelease'.
> Keystore file 'D:\flutterapps\testapp\android\app\ D: lutterappspublishkey.jks' not found for signing config 'release'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 4s

I experienced the same issue with my Flutter app and here's how I solved it on my Mac.

  1. Ensure that your key.properties file is located inside the android directory, so the path should be android/key.properties.

  2. Your key.properties file should have the following structure:

    storePassword=Yourpasswordgoeshere 
keyPassword=Yourpasswordgoeshere
keyAlias=key
storeFile=/Users/yourUsername/Apps/yourappname/android/app/upload-keystore.jks

  3. If you're unsure what your keyAlias key is, open your terminal and run this command keytool -list -v -keystore /path/to/your/keystore , replacing /path/to/your/keystore with the actual keystore path which is provided when you run the keytool -genkey.. command. To find your keyAlias, search for
    -alias.

Alternatively, if you used Android Studio to generate your keystore, go to Build>Generate Signed Bundle/APK, select APK and the key store path, password and alias can be found there.

  1. Open your build.gradle file located at android>app>build.gradle. Make sure you have added the following code above the android block and below 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 {..............// IGNORE THIS LINE

  2. Within the defaultConfig block, check that you have also added the following code:

    signingConfigs {
 release {
     keyAlias keystoreProperties['keyAlias']
     keyPassword keystoreProperties['keyPassword']
     storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
     storePassword keystoreProperties['storePassword']
    }
}
 buildTypes {
    release {
     signingConfig signingConfigs.release
     minifyEnabled true
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
   }
 }

The minifyEnabled and proguardFiles keys are used for code shrinking and obfuscation and are optional.

  1. Run flutter clean && flutter pub get
  2. Run flutter build appbundle. If the build process completes successfully, you will see ✓ Built build/app/outputs/bundle/release/app-release.aab. This path indicates where the app bundle is stored within your Flutter project.

I was having the same issue, I ended up having quotes around my path.

In key.properties, change

storeFile="D:\\mypath\\tokeystore\\key.jks"

to

storeFile=D:\\mypath\\tokeystore\\key.jks

In build.gradle

Replace

def keystorePropertiesFile = rootProject.file('key.properties')

to

def keystorePropertiesFile = rootProject.file('app/key.properties')

Yeah, for me... I forgot to change my signingConfig to singingConfigs.release in my build.gradle file.

    buildTypes {
        release {
           //CHANGE THIS TO RELEASE
            signingConfig signingConfigs.debug
        }
    }

On Windows you have to use 2 backslashes to indicate the path separation. In your key.properties, you should have something like this:

storeFile=D:\\flutterapps\\testapp\\key.jks

You don't need to copy your key.jks file to your flutter project.

modified key.properties file with 

storePassword=123456
keyPassword=123456
keyAlias=key
storeFile=key.jks

instead of this 

storePassword=123456
keyPassword=123456
keyAlias=key
storeFile=D:\flutterapps\testapp\key.jks

and also moved key.jks to D:\flutterapps\testapp\android\app\key.jks

as this path shown in error inside terminal

Thanks all.

it's wherever call it from in your build.gradle. insert this:

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

and call this in above your android{}:

def keystorePropertiesFile = rootProject.file("key.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

and that key.properties file (which should be in your root android folder) should have this:

storePassword=12345
keyPassword=12345
keyAlias=key
storeFile=/Users/me/somekey.jks
