Android: Keystore password prompt won't show up

After updating platform to Android 6.0.0 keystore password prompt won't work anymore.
This happens when doing release build with command

cordova build --release --buildConfig build.json

Where build.json contains keystore and alias properties.
On previous version this showed a prompt that asked for keystore passwords.
With new version build fails with an error because it won't have the correct passwords.

Execution failed for task ':packageArmv7Release'.
> com.android.ide.common.signing.KeytoolException: Failed to read key STORE from store "KEYSTORE": Keystore was tampered with, or password was incorrect

I'm using Cordova 6.4.0 and have tested this with Android 5.1.1 and 5.2.2 and both of those work. Android 6.1.0 has the same issue.

It seems to me that validateReleaseSigning task isn't being added to gradle tasks anymore for some reason, which means prompt won't be shown.
I think this function is supposed to show the prompt

gradle.taskGraph.whenReady { taskGraph ->
    taskGraph.getAllTasks().each() { task ->
        if (task.name == 'validateReleaseSigning') {
            promptForReleaseKeyPassword()
        }
    }
}
