Gradle Project Sync failed in Android Studio

Question

I open my project in android studio by importing the build.gradle, the project used to work fine before but now I get an error that says that the gradle project sync failed. I tried a build and it says Task '' not found in the root project 'projectname'.

This what shows up in log files.
