Multiple dependencies are trying to import “UNEXPECTED TOP-LEVEL EXCEPTION:”

Question

I have two libraries on my proyect.

https://github.com/rengwuxian/MaterialEditText

https://github.com/navasmdc/MaterialDesignLibrary

It compiles, but when I run the program it reports an error.

UNEXPECTED TOP-LEVEL EXCEPTION:
Error:Execution failed for task ':app:dexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    C:\Users\Alvaro\AppData\Local\Android\sdk\build-tools\21.1.2\dx.bat --dex --no-optimize --output D:\ALVARO\AndroidStudioProjects\Proyecto\app\build\intermediates\dex\debug --input-list=D:\Alva\AndroidStudioProjects\Proyecto\app\build\intermediates\tmp\dex\debug\inputList.txt
Error Code:

I KNOW THE PROBLEM, BUT I CAN'T SOLVE

Problem

Multiple dependencies are trying to import nineoldandroids exactly "nineoldandroids"

app build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.example.alva.proyecto"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt')
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:21.0.3'

    //seconds library
    compile project(':materialDesign')

    //first library
    compile project(':EditText') 
}

first library build.gradle

apply plugin: 'com.android.library'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 21
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.android.support:support-annotations:21.0.3'
    compile 'com.nineoldandroids:library:2.4.0'
    compile 'com.android.support:appcompat-v7:21.0.3'
}

seconds library build.gradle

apply plugin: 'com.android.library'

android {
    compileSdkVersion 8
    buildToolsVersion "19.1.0"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 8
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:18.+'
    compile files('libs/nineoldandroids-2.4.0.jar')
}

I have tried:

1. Put on "app" build.gradle:

compile project(':EditText') {

        exclude group: 'com.nineoldandroids', module: 'library:2.4.0'
    }

NOT WORKS, IT'S REPORTS AN ERROR

Error:(31, 0) Gradle DSL method not found: 'exclude()'
Possible causes:<ul><li>The project 'Proyecto' may be using a version of Gradle that does not contain the method.
<a href="openGradleSettings">Gradle settings</a></li><li>The build file may be missing a Gradle plugin.
<a href="apply.gradle.plugin">Apply Gradle plugin</a></li>

2. Remove "nineoldandroids" from seconds library, NOT WORKS

Any suggestions?

Answer 1

I don't know how to import using their respective artifacts

It is in the documentation for each library.

The MaterialEditText "Download" section cites:

compile 'com.rengwuxian.materialedittext:library:1.8.2'

The "How to Use" section of MaterialDesignLibrary cites:

repositories {
    jcenter()
}

dependencies {
    compile 'com.github.navasmdc:MaterialDesign:1.+@aar'
}

Then, Gradle will (hopefully) be able to detect that both of these dependencies themselves depend upon nineoldandroids and resolve the conflict. I say "hopefully" because whichever library the "seconds library build.gradle" comes from uses a local copy of nineoldandroids, which is not a good idea. Neither GitHub repo seems to have that particular build.gradle file, though, so you may be OK.
