I'm developing android app under intellij and gradle. and using following way to generate keystore file:

keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

then used the keystore file in build.gradle:

signingConfigs {
    robert {
        storePassword 'robert'
        storeFile file('/Users/bournewang/Documents/Project/android.keystore')
        keyPassword 'robert'
        keyAlias 'mike'
    }
}

when finally trying to generate signed apk file: ./gradlew assembleRelease

it gives the error:

Execution failed for task ':Myexample:packageRelease'.

adding --info and --stacktrace to the gradlew command line should give you more info that might help pinpoint the problem. – Scott Barta
I was facing this because the "key alias" I typed in didn't exist in the keystore. This answer helped me out. – Sufian

Check your keystore file for first, in you example you creating file with name my-release-key.keystore. If its correct and really present in folder Users/bournewang/Documents/Project check alias, in your example it is -alias alias_name, but in config you specified alias mike

In order to find out what's wrong you can use gradle's signingReport command.

On mac:

./gradlew signingReport

On Windows:

gradlew signingReport

Most likely that your key alias does not exist for your keystore file.

This answer should fix your signing issue ;)

Removing double-quotes solve my problem, now its:

DEBUG_STORE_PASSWORD=androiddebug
DEBUG_KEY_ALIAS=androiddebug
DEBUG_KEY_PASSWORD=androiddebug

In my case, while copying the text from other source it somehow included the space at the end of clipboard entry. That way the key password had a space at the end.

For someone not using the signing configs and trying to test out the Cordova Release command by typing all the parameters at command line, you may need to enclose your passwords with single quotes if you have special characters in your password

cordova run android --release -- --keystore=../my-release-key.keystore --storePassword='password' --alias=alias_name --password='password'

The big thing is either the alias or the other password is wrong. Kindly check your passwords and your issue is solved. Incase you have forgotten password, you can recover it from the androidStuido3.0/System/Log ... Search for the keyword password and their you are saved

I got same error today.

Execution failed for task ':app:packageRelease'. A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable com.android.ide.common.signing.KeytoolException: Failed to read key news from store "E:\keystore\news.jks": Keystore was tampered with, or password was incorrect

I had same key password and key store password. But i wrote a wrong password.

In Android Studio go to Build > Clean Project then re-generate signed APK using Build > Generate Signed Bundle / APK... and then clear password-fields and re-enter your passwords

in my case for some reason, after updating android studio to the last stable version, the password that was always by default got changed, i just had to set correct password again and it worked

It could be any one of the parameter, not just the file name or alias - for me it was the Key Password.
