Gradle build fail

I don't know what to do anymore, I can't build to Android anymore, there's some issue with the gradle build, I tried to remove the Android folder and it only became worse with more errors, this is the best case I could achieve, this single error-

CommandInvokationFailure: Gradle build failed.
