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

Question

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

Which steps are you referring to from the official site? What is your directory structure? — Iain Duncan, Dec 29 '18 at 21:15
It seems that it’s serching the .jks file inside the app folder and not the parent. Tey put it on ./android/app. Btw how did you set up the signin keystore? With AS, by hand in gradle file, or what? — shadowsheep, Dec 29 '18 at 21:17
I set signing by this keytool -genkey -v -keystore D:\flutterapps\testapp\key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key in terminal and it gave succsesful mesaage and created key.jks file also in that path — Gudguy, Dec 29 '18 at 21:25
It considering its path as key.properties file path instead key.jks — Gudguy, Dec 29 '18 at 21:33

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.

This should be actually the right and marked answer. – Néstor Aug 24 '21 at 14:35

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 not the cause of the problem. The real cause is in windows's backslashes. The keytool thinks those are escape characters and just ignores them. You could whether do this D:\\flutterapps\\testapp\\key.jks or this D:/flutterapps/testapp/key.jks to avoid the problem. – Konstantin Nov 22 '19 at 11:17

If you are moving your key inside your app (not recommended), don't forget to add a line `key.jks` to your .gitignore file because this file should not be uploaded to any public repository. Also you need \\ instead of \ as mentioned above. – Md Azharuddin Jul 21 '20 at 09:32

With a second backslash per directory is enough. You don't need to move any key file. – Néstor Aug 24 '21 at 14:36
To emphasize the points above: MOVING YOUR .JKS INTO YOUR ANDROID DIRECTORY IS MERELY A *"WORKAROUND"*! It is *NOT* "best practice"! The real problem was the backslashes. You have two choices; either will work: A) `D:\\flutterapps\\testapp\\key.jks` or B) `D:/flutterapps/testapp/key.jks` – paulsm4 Nov 27 '21 at 18:45

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

it giving this weird error path Keystore file 'D:\flutterapps\publish\android\app\D: lutterappspublishkey.jks' not found for signing config 'release'. – Gudguy Dec 29 '18 at 21:20
what did you set as the storeFile? – blaneyneil Dec 29 '18 at 21:24
my key store file name is key.jks but it taking something as Keystore file 'D:\flutterapps\testapp\android\app\ (less than sign) D: lutterappspublishkey.jks (greater than sign)' not found for signing config 'release'. – Gudguy Dec 29 '18 at 21:29
you sure you're calling in the key.properties file? – blaneyneil Dec 29 '18 at 21:41

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
        }
    }

In build.gradle

Replace

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

to

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

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

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

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

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

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.

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

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.

Run flutter clean && flutter pub get
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.
