导航XML不会为AAR库生成

Question

当我生成aar文件时，我使用andriodx导航组件开发了AAR库，我发现包含空导航文件夹的aar文件在这里出了什么问题

这是我的gradle文件

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    //navigation component dependency
    def nav_version_ktx = "2.1.0-alpha06"
    implementation "androidx.navigation:navigation-fragment-ktx:$nav_version_ktx"
    implementation "androidx.navigation:navigation-ui-ktx:$nav_version_ktx"
}
