java - 错误: Failed to resolve: android.支持:support. v7 :29. 0.2

Question

我是 Android Studio 的新手。我在编码部分遇到问题。运行代码时显示错误。 Thw gradle部分如下所示

apply plugin: 'com.android.application'
android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example.fallprediction"
        minSdkVersion 14
        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'
        }
    }
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.13'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'android.support:support.v7:29.0.2'
}

错误是 错误:无法解决:android.support:support.v7:29.0.2 在项目结构对话框中显示 受影响的模块:应用程序

请帮我解决这个错误
