如何为Android导入扩展品牌？

Question

我正在尝试导入我的项目这个库，但是当我尝试同步它时会出现这个错误：

Error:(25, 13) Failed to resolve: asia.ivity.android:marqueeview:{insert-latest-version}
<a href="openFile:C:/Users/OFTECNICA2/Desktop/APPs-Proyectos/EjemploScroll/app/build.gradle">Show in File</a><br><a href="open.dependency.in.project.structure">Show in Project Structure dialog</a>

这是library，我该怎么办？

编辑：

我已添加了渐变以获得更多帮助：

Graddle app：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.example.oftecnica2.ejemploscroll"

        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
}

Graddle项目

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir

@Sergio忘记了库，你可以将库代码给自己的项目...
