Flutter - Gradle task assembleRelease failed with exit code 1

Question

I am getting the following error while building my flutter app. I am not getting any errors while testing the app on an emulator, and it's working fine. I don't know what's wrong with the building. I appreciate any help you can provide.

flutter version: v2.5.3 | devtools: v2.8.0

I am using this command to build the app:

flutter build apk --split-per-abi

here is the error log:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:packageRelease'.

Here is the solution:

try this command:

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

with extra attribute

-storetype JKS

note: The -storetype JKS tag is only required for Java 9 or newer. As of the Java 9 release, the keystore type defaults to PKS12.
