Execution failed for task ':app:signReleaseBundle'

I have this error at the moment to make flutter build appbundle

this is the error:

FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:signReleaseBundle'. > A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade > Failed to read key sd from store "C:\flutter_project\cursin2\cursin-main\android\app\upload-keystore.jks": Integrity check failed: java.security.NoSuchAlgorithmException: Algorithm HmacPBESHA256 not available * 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 BUILD FAILED in 6s Running Gradle task 'bundleRelease'... 9,1s Gradle task bundleRelease failed with exit code 1 PS C:\flutter_project\cursin2\cursin-main> 

i've tried all ways to fix it, but the error is still appearing.

my key.properties:

storePassword=ul109000 keyPassword=ul109000 keyAlias=sd storeFile=C:/flutter_project/cursin2/cursin-main/android/app/upload-keystore.jks

in android app/ build.gradle

inside android tag

def keystoreProperties = new Properties() def keystorePropertiesFile = rootProject.file('key.properties') if (keystorePropertiesFile.exists()) { keystoreProperties.load(new FileInputStream(keystorePropertiesFile)) } signingConfigs { debug { keyAlias keystoreProperties['keyAlias'] keyPassword keystoreProperties['keyPassword'] storeFile file(keystoreProperties['storeFile']) storePassword keystoreProperties['storePassword'] } release { keyAlias keystoreProperties['keyAlias'] keyPassword keystoreProperties['keyPassword'] storeFile file(keystoreProperties['storeFile']) storePassword keystoreProperties['storePassword'] } } 

storeFile path will be ./upload-keystore.jks

and

 buildTypes { debug { signingConfig signingConfigs.debug } release { minifyEnabled true shrinkResources true signingConfig signingConfigs.release } } 

In my case key.properties file was missing(you can find that in android/build.gradle). If you have cloned your repo from github and then try to create appbundle then this issue may arise.

Generate new key.properties or take previous key.properties file to create appbundle.

The only method to solve this, that worked for me was:

1. flutter clean
2. edit the path i used in key propeties.

For example: "./upload-keystore.jks" to "C:/key/myapp/upload-keystore.jks" 3. flutter build appbundle

Delete this:

debug { storeFile file(storeFile_) storePassword storePassword_ keyAlias keyAlias_ keyPassword keyPassword_ } 

First

in android app/ build.gradle

replace this

 buildTypes { release { signingConfig signingConfigs.release } } 

with this

 buildTypes { debug { signingConfig signingConfigs.debug } release { minifyEnabled true shrinkResources true signingConfig signingConfigs.release } } 

Second

remove upload-keystore.jks in your generation path in my case (Ubuntu OS) the path is /home/user/upload-keystore.jks

Third

genrate a new key with with extra attribute

-storetype JKS 

for Linux

keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload -storetype JKS
