BUILD FAILED in 3s
Exception: Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

I tried updating my Gradle to the latest version as well as my Java.

re-initiated a fresh project and tried to launch the default flutter application but no difference.

any help would be appreciated

  • Please take look at this answer: https://stackoverflow.com/a/47127602/14388778. Also why would you delete .android folder from the project? Is it a desktop app? iOS only? If it's for android I'd suggest making a new project and moving lib files with pubspec to the new project. You could try `flutter clean` and `flutter create android` but I doubt it'll help at this point. – Piotr Aug 20 '22 at 13:26

you should change build.gradle to classpath 'com.android.tools.build:gradle:7.2.2' and do sync with gradle and its work for me. tell me if this fix you problem.
