Invalid Keystore Format - Flutter

I have generated a keystore by following the flutter documentation with the following command:

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

Unfortunately I believe that my Flutter uses a different Java location in order to verify the key and I get the following error:

* What went wrong:
Execution failed for task ':app:packageRelease'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > com.android.ide.common.signing.KeytoolException: Failed to read key upload from store "/home/<username>/Documents/github/keystores/upload-keystore.jks": Invalid keystore format

The flutter doctor -v returns the following:

an which keytool returns:

/usr/bin/keytool

I believe I might have to change the Java path used by Flutter but have no idea how to o it an if it is even remotely what I nee to do.

Solution

  • It ended up being a keytool generation problem. As expected my app key was generated with a different keytool installed on my machine. I had to generate the key with the right keytool again and request Google to change it.
