Could not install Gradle distribution from 'https://services.gradle.org/distributions/gradle-2.1-all.zip'

It could be that the gradle-2.1 distribution specified by the wrapper was not downloaded properly. This was the root cause of the same problem in my environment.

Look into this directory:

ls -l ~/.gradle/wrapper/dists/

In there you should find a gradle-2.1 folder. Delete it like so:

rm -rf ~/.gradle/wrapper/dists/gradle-2.1-bin/

Restart IntelliJ, after that it will restart the download from the beginning and hopefully work.

If you are on Windows, you can go to:

C:\Users\{your_name}\.gradle

And delete all the references of the gradle package you can find in those folders:

1. caches
2. daemon
3. wrapper

Then re-open your project and sync gradle

First check your Internet conection..

or try with

Tools -> Android -> Sync

or Try

File -> Settings -> Gradle -> Check Offline Work
