How to use the latest gradle version in Android Studio

In gradle-wrapper.properties I already have the up to date version :

distributionUrl=http\://services.gradle.org/distributions/gradle-2.12-all.zip

As suggested in another post, I believe I have the latest version of gradle plugin. In File/Project Structure/Project I have :

Another post on SO said to right click on my Java directory and select from the menu, 'Mark Directory as Source'. But this option does not even appear in my menu. My version of Android Studio is AS 2.1 Preview 5.

I can't select my java folder in blue, as it should be (marked as source) and my MainActivity java file has a funny red symbol. I seem unable to make it a java class file :

Any idea how to solve this problem on this buggy platform?

Basically, in my gradle-wrapper.properties I put this line :

    distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip 

// or whatever latest version here : https://services.gradle.org/distributions

Android Studio: Add jar as library

I've been struggling with the same thing for many hours, trying to get the Gson jar to work no less. I finally cracked it – here are the steps I took:

Put the Gson jar (in my case, gson-2.2.4.jar) into the libs folder
Right click it and hit 'Add as library'
Ensure that compile files('libs/gson-2.2.4.jar') is in your build.gradle file (or compile fileTree(dir: 'libs', include: '*.jar') if you are using many jar files)

Edit : Use implementation files('libs/gson-2.2.4.jar') (or implementation fileTree(dir: 'libs', include: '*.jar')) in Android Studio 3.0+
Do a clean build (you can probably do this fine in Android Studio, but to make sure I navigated in a terminal to the root folder of my app and typed gradlew clean. I'm on Mac OS X, the command might be different on your system

After I did the above four, it started working fine. I think the 'Add as library' step was the one I'd previously missed, and it didn't work until I cleaned it either.

[Edit - added the build.gradle step which is also necessary as others have pointed out]

Android Studio – Gradle sync project failed

The Android plugin 0.8.x doesn't support Gradle 1.11, you need to use 1.10.

You can read the proper error message in the "Gradle Console" tab.

EDIT

You need to change gradle/wrapper/gradle-wrapper.properties file in this way:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=http\://services.gradle.org/distributions/gradle-1.10-all.zip
