android - 无法将 Maven 的库包含到 Android Studio

Question

我有一个项目，我想更改它以使用 Maven 来包含 OSMDroid 的库而不是本地依赖项。根据OSM Droid tutorial我需要包含以下依赖项:

dependencies {
    compile 'org.osmdroid:osmdroid-android:4.2'
    compile 'org.slf4j:slf4j-simple:1.6.1'
}

然后从这个 SO post我需要添加一行才能通过 gradle 使用 Maven:

repositories {
    mavenCentral()
}

这使得我的基本 build.gradle for Module: app 变成了这个:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.1"

    defaultConfig {
        applicationId "se.einarsundgren.anApp"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
     }
 }

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'org.osmdroid:osmdroid-android:4.2'
    compile 'org.slf4j:slf4j-simple:1.6.1'
}

这会导致 Gradle 同步错误:

 Error:(29, 13) Failed to resolve: org.slf4j:slf4j-simple:1.6.1
 Error:(28, 13) Failed to resolve: org.osmdroid:osmdroid-android:4.2

这是我在尝试编译时从 Gradle 构建中得到的错误:

Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
   > Could not resolve org.osmdroid:osmdroid-android:4.4.

         > peer not authenticated

这可能是一个简单的错误，因为我是 Maven 和 Gradle 细节的新手。但我不知道为什么这不起作用。

解决问题的方法与 this question 中的建议相同我将 repositories 标签更改为:

repositories {
    mavenCentral()
        jcenter {
            url "http://jcenter.bintray.com/"
        }

}
