android - 如何将 .aar 依赖项包含到 Android 库 .aar 文件中

Question

我写了一些库，它有一部分 UI。此外，此库使用其他库。我想提供版本 .aar 以在任何应用程序中使用此 UI 部分。

我的图书馆有下一个依赖:

    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.android.support:support-v4:23.1.1'
    compile ('com.android.support:recyclerview-v7:22.2.1'){
        exclude group: 'com.android.support', module: 'support-v4'
    }
    compile 'com.inthecheesefactory.thecheeselibrary:stated-fragment-support-v4:0.10.0'

    //Http communication, websockets, etc.
    compile 'com.squareup.okhttp:okhttp:2.4.0'
    compile 'com.squareup.retrofit:retrofit:1.9.0'

    //Fonts
    compile 'uk.co.chrisjenx:calligraphy:2.1.0'

    //Unit tests
    testCompile 'junit:junit:4.12'
    testCompile 'org.mockito:mockito-core:1.9.5'

    //Other
    compile ('org.apache.commons:commons-lang3:3.4'){
        exclude group: 'org.apache.httpcomponents'
    }

    //Reactive programmnig
    compile 'io.reactivex:rxjava:1.0.13'
    compile 'io.reactivex:rxandroid:0.25.0'

    compile 'com.github.bumptech.glide:glide:3.6.1'

当我构建 .aar 时一切正常，但是当我将此 .aar 包含到另一个应用程序中时，我遇到了下一个问题:

1). ./gradlew clean build

/home/user/projects/MainApp/app/build/intermediates/exploded-aar/com.my.sdk/SDK/0.0.1/res/values/values.xml:78:21-29 : No resource found that matches the given name: attr 'fontPath'.

/home/user/projects/MainApp/app/build/intermediates/exploded-aar/com.my.sdk/SDK/0.0.1/res/values/values.xml:78:21-29 : No resource found that matches the given name: attr 'fontPath'.

:app:processDebugResources FAILED

解决方案很简单——添加到 MainApp/app/build.gradle 下一行:

编译 'uk.co.chrisjenx:calligraphy:2.1.0'

2). 当我运行 MainApp 时出现此错误:

java.lang.NoClassDefFoundError: com.my.sdk.ui.fragment.DialogAppNotInstalledFragment

为了解决这个问题，我需要将 compile 'com.inthecheesefactory.thecheeselibrary:stated-fragment-support-v4:0.10.0' 添加到 MainApp/app/build.gradle.

与其他依赖项相同。

结果我只需要复制粘贴我的library项目中的所有依赖项到MainApp项目。

是否有可能使library aar包含所有必需的依赖项？
