I'm trying to build the project with offline-mode in Android Studio. So, Unzip the gradle-plugin (version 4.4) and set Gradle path & Service directory path. Finally check 'Offline work'. When Sync the gradle, it occur the problem.
The Error Message
'No cached version of com.android.tools.build:gradle:3.1.4 available for offline mode.'
