Android NDK Integration: Error: Unable to find method 'com.android.build.gradle.internal.Application

Issue

I'm following this tutorial and the Teapot example by google.

This is my gradle:

apply plugin: 'com.android.model.application'

model {

android {
    compileSdkVersion = 23
    buildToolsVersion = "23.0.2"

    defaultConfig.with {
        applicationId = "..."
        minSdkVersion.apiLevel = 22
        targetSdkVersion.apiLevel = 23
        versionCode = 1
        versionName = "1.0"
    }

}


android.buildTypes {

    release {
        minifyEnabled = false
        proguardFiles.add(file('proguard-android.txt'))
    }
}

}

 dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.support:design:23.2.1'
}

And I get the following error while trying to sync:

    Error:Unable to find method 
'com.android.build.gradle.internal.ApplicationTaskManager.<init>       
    (Lorg/gradle/api/Project;Lcom/android/builder/core/AndroidBuilder;
        Landroid/databinding/tool/DataBindingBuilder;
     Lcom/android/build/gradle/AndroidConfig;Lcom/android/build/gradle/internal/
 SdkHandler;Lcom/android/build/gradle/internal/DependencyManager;Lorg/gradle/tooling/
    provider/model/ToolingModelBuilderRegistry;)V'.

I tried playing with the dependecies including removing them completely, restarting Android studio but I'm lost as it seems to be ok.

My versions:

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

 classpath 'com.android.tools.build:gradle:2.1.0-alpha5'
 classpath 'com.android.tools.build:gradle-experimental:0.6.0-rc3'

Solution

I've solved it, it happened because I had 2 classpaths.

Once I removed the classpath 'com.android.tools.build:gradle:2.1.0-alpha5'

It worked.
