我正在尝试将CoordinatorLayoutAndroidx一起使用,但出现此错误

The following classes could not be found: androidx.coordinatorlayout.widget.CoordinatorLayout

尽管我依赖它,但我不知道为什么会收到此错误。

我也尝试更改androidx.appcompat的版本,但也遇到相同的错误

Build.Gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 29
buildToolsVersion "29.0.2"
defaultConfig {
    applicationId "com.example.bitprojecttask"
    minSdkVersion 15
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
