I get error when I use the apply plugin: 'com.android.library'

Question

I created a normal project in android studio and considering to the tutorials I wanted to create an aar file from that project but I get the following error:

Gradle: 
FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\tec\AndroidStudioProjects\B\B\build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':B'.
> Plugin with id 'com.android.library' not found.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
 Could not execute build using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.6-bin.zip'.

My gradle file is as follows:

apply plugin: 'com.android.library'
buildscript {
    repositories {
        maven { url 'http://repo1.maven.org/maven2' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android'

dependencies {
    compile files('libs/android-support-v4.jar')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}

Answer 1

You have to update your script:

First of all use the latest gradle plugin.

classpath 'com.android.tools.build:gradle:1.3.0'

Then update your gradle wrapper. Open up this file in your project:

<Project>/gradle/wrapper/gradle-wrapper.properties

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

Finally remove the line apply plugin: 'android'
