错误：无法解决：Crosswalk

Question

我正在尝试使用Crosswalk制作SDK。所以首先我开始使用
制作一个示例应用程序 compile 'org.xwalk:xwalk_core_library:23.53.589.4'。它有效。然后我尝试使用此SDK。但它并没有像我预期的那样奏效。

gradle文件

apply plugin: 'com.android.library'
repositories {
    maven {
        url 'https://download.01.org/crosswalk/releases/crosswalk/android/maven2'
    }
}
android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
    compile 'org.xwalk:xwalk_core_library:23.53.589.4'
    testCompile 'junit:junit:4.12'

}
