Gradle version 1.8 is required. Current version is 1.9

Question

Android Studio just updated itself to 0.4.2, and now fails parsing my project with the message:

Gradle version 1.8 is required. Current version is 1.9

Answer 1

Update distributionUrl mentioned in your YOUR_PROJECT/gradle/gradle-wrapper.properties file, Studio(0.4.2) should automatically prompt for auto fix while gradle sync but if it didn't do it manually. distributionUrl should be like

distributionUrl=http\://services.gradle.org/distributions/gradle-1.9-all.zip

Update all build.gradle files inside your project or if you are using top level build.gradle file for defining gradle version update in that only with

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}

Android Studio(0.4.2) only supports Gradle 1.9 which can be defined using gradle:0.7.+ in dependency classpath.

Answer 2

In your project root is a gradle folder. Within that folder is a file 'gradle-wrapper.properties' open that file in a text editor and change the version in the distributionUrl from 1.8 to 1.9.

Then re-open your project.
