Android Studio 3.1.1的build.gradle中的api和实现

我有一个图书馆项目“模块核心”。我已经将所有依赖项从compile更改为api，因为我也想在我的主项目中使用所有这些依赖项。以下是“我的库中依赖项”项目的外观：

apply plugin: 'com.android.library'
        .
        .
        .
        .
api("com.android.support:appcompat-v7:$rootConfiguration.supportLibraryVersion") {
        force = true
    }
    api("com.android.support:design:$rootConfiguration.supportLibraryVersion") {
        force = true
    }
    api("com.android.support:support-v13:$rootConfiguration.supportLibraryVersion") {
        force = true
    }
    api("com.android.support:cardview-v7:$rootConfiguration.supportLibraryVersion") {
        force = true
    }
    api("com.android.support:support-dynamic-animation:$rootConfiguration.supportLibraryVersion") {
        force = true
    }

现在我指的是我的主要应用程序项目中的模块核心：

apply plugin: 'com.android.application'
.
.
.
. 
implementation "com.example.module_core:module_core:$rootConfiguration.coreLibraryVersion"

当我编译我的应用程序项目时，它会给我错误

error: style attribute 'attr/tabIndicatorColor (aka com.example.mva:attr/tabIndicatorColor)' not found. 

但当我在我的库项目中更改api进行编译时，它工作得很好。 api不应该像编译一样工作吗？根据我的理解，如果我们使用实现，那么上述错误就会出现。 以下是aapt2错误日志的详细信息：

非常感谢您的帮助。

您是否尝试过使用

实现
而不是
api
？请尝试使用“实现”代替。是的，我也尝试过实现。我猜当我们通过Maven repository使用依赖项时，是否有任何限制，因为我所有的依赖项都在核心模块中，我将其用作“com.example.module\u core:module\u core”。但是，如果我在使用compileproject（：module_core）的项目中直接使用核心模块，它就可以正常工作。
