How to cleanly tear down Cordova, Gradle and Android SDK?

Question

Android

Cordova is broken, projects are not built, I get the error:
A problem occurred configuring project ':CordovaLib'
> Failed to notify project evaluation listener.
> org/objectweb/asm/ClassVisitor
Google clarified only that when trying to update Gradle (or its scripts), Android Studio slipped him some kind of dependency of the wrong version. I can’t figure it all out, because I’m just trying to get to know Cordova, so now I just want to return everything as it was.
Accordingly, the question is: how to demolish the Android SDK, Cordova, Gradle and everything else so that their scripts and settings files are not left anywhere? An independent attempt to do this was unsuccessful - the reinstalled cordova still gives the same error.
