android - 无法将 BottomBar 添加到 Android Studio

Question

我正在尝试将 BottomBar(第 3 方库)作为模块添加到我的 android studio 项目中。我收到错误 Error: (4, 0) Cannot get property 'compileSdkVersion' on extra properties extension 因为它不存在并且指向 build.gradle 文件。我不确定出了什么问题。感谢任何帮助。

底栏:
https://github.com/roughike/BottomBar/blob/master/README.md#common-problems-and-solutions

apply plugin: 'com.android.application'

android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion

defaultConfig {
    applicationId "com.example.bottombar.sample"
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(':bottom-bar')
compile 'com.android.support:appcompat-v7:' + rootProject.ext.supportLibraryVersion
compile 'com.android.support:design:' + rootProject.ext.supportLibraryVersion

testCompile 'junit:junit:' + rootProject.ext.junitVersion
}

算了，我想通了。我不需要将其作为模块导入，只需将其添加为依赖项即可。
