Android Studio 1.3.2 error when refreshing gradle

问题:

I generated build.gradle file from eclipse and import it to android studio.

However, it returns error after "refreshing gradle" :

Gradle sync failed: Could not find com.android.tools.build:gradle-1.12

This is the classpath :

classpath 'com.android.tools.build:gradle-1.12'

This is what i have in my gradle directory :

C:\Users\user\.gradle\wrapper\dists\gradle-1.12-all

And this is what i have in gradle-wrapper.properties file in my project's root :

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-1.12-all.zip

This is the error log :

java.io.FileNotFoundException: Unable to find path to Gradle home directory
    at com.android.tools.idea.gradle.util.GradleUtil.stopAllGradleDaemons(GradleUtil.java:462)

What should i do?

I have tried to use different internet connections, with/without proxy.

Thanks for your time.

Don't confuse the gradle-plugin for Android and gradle.
They are different. You can find more info about the android plugin here

With the classpath inside your gradle files, you set the version of the android plugin for Gradle.

Change your classpath using:

classpath 'com.android.tools.build:gradle:1.3.1'

instead of:

classpath 'com.android.tools.build:gradle-1.12'

In the gradle-wrapper.properties file you set the version of the Gradle. For example the 2.4 version.

distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip

I recommend you to use gradle 2.4, you can download it here. Then, extract the downloaded file into C:\Program Files\Android\Android Studio\gradle. After that, open File > Settings from Android Studio. On the searchbox, type gradle and search.

Open build.gradle from the main project and type classpath 'com.android.tools.build:gradle:1.3.0' under dependencies:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

Finally, rebuild your project in Build > Rebuild project.
