Gradle sync Error:Configuration with name 'default' not found

Question

I want to add an external library GuillotineMenu-Android in my application. I followed the steps given in the most upvoted answer to an existing question How do I add a library project to the Android Studio? But I am facing error when I try to build project after step 6 i.e. when added dependency in app/build.gradle as compile project(":guillotinemenu"). I tried all the stackoverflow links related to this error but its not working out. I have made a folder named libs in my app directory and copied the project folder guillotine menu there. Here is my build.gradle(Module:app) file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"
    defaultConfig {
        applicationId "com.sunshine.bbreaker.appet_i"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:recyclerview-v7:+'
    compile 'com.github.navasmdc:MaterialDesign:1.+@aar'
    compile 'com.android.support:appcompat-v7:22.0.+'

    // GuillotineMenu
    compile project(":guillotinemenu")
}

settings.gradle(Project Settings) file:

    include ':app', ':guillotinemenu'
project(':guillotinemenu').projectDir = new File('libs/guillotinemenu')

build.gradle(Project:guillotinemenu) file:

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.2.3'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}} allprojects {
repositories {
    jcenter()
}}

settings.gradle(Project:guillotinemenu) file:

include ':app', ':library'

build.gradle(guillotinemenu) file:

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.yalantis.guillotine.sample"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile project(':library')
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.jakewharton:butterknife:6.1.0'
}

Let me know if you need any more information. Thanks in advance.

I have already posted named as 'build.gradle(Project:guillotinemenu)' — gautamprajapati, Jul 11 '15 at 07:42
Chek below. Your 'build.gradle(Project:guillotinemenu)' is a top level file. Your library must have a build.gradle inside. — Gabriele Mariotti, Jul 11 '15 at 11:33
Yeah, thanks I added the build.gradle file of the guillotinemenu library. — gautamprajapati, Jul 12 '15 at 04:30
This build.gradle is a top level file. It can't work as library. Check the updated answer. — Gabriele Mariotti, Jul 12 '15 at 05:55

You should have a structure like this:

projectRoot
  app
     build.gradle
  library
     build.gradle
  build.gradle
  settings.gradle

Each module has own build.gradle file. Also the root/settings.gradle defines all modules inside a project. Don't use another settings.gradle inside your module.

In settings.gradle :

include ':app', ':library'

In build.gradle

    buildscript {
        repositories {
            jcenter()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:1.2.3'

            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }
    allprojects {
        repositories {
            jcenter()
        }
    }

In library/build.gradle

apply plugin: 'com.android.library'

android {
    compileSdkVersion ...
    buildToolsVersion ...

    defaultConfig {
        ....
    }

}

dependencies {
   //....
}

In app/build.gradle use your file but change:

dependencies {
    //...
    // GuillotineMenu
    compile project(":library")
}

UPDATE:

After your comment below, I think that in your case the library folder is the root folder of another project. It means that you should refer to the module inside this project.

    projectRoot
      app
         build.gradle
      libs
         guillotinemenu
           build.gradle //top level file of guillotinemenu project
    -->>   module       
              build.gradle  //build.gradle of the module

So change the settings.gradle of your projectRoot.

 include ':app', ':guillotinemenu'
 project(':guillotinemenu').projectDir = new File('libs/guillotinemenu/module')

The module (libs/guillotinemenu/module) should have a build.gradle as the library/build.gradle described above.

the library guillotinemenu is already having its build.gradle file and settings.gradle file. It is using another library inside it which have just a build.gradle file. So, do you want me to change or delete settings.gradle of guillotinemenu project? — gautamprajapati, Jul 12 '15 at 04:40
@brainbreaker It wasn't clear in the original question, sorry. I've updated the answer. If the guillotinemenu is another project you have to point the module inside this project — Gabriele Mariotti, Jul 12 '15 at 05:55
