我無法安裝 androidx.ppreferences Library

Question

我想从androidx安装首选项库。当我转到项目结构添加此库时：1.我没有1.1.0版本。我只有1.1.0-alpha05和1.0.0版本。2.当我想安装这个库的任何版本时，我会得到：错误：无法解析：androidx。首选项：首选项：VERSION

**我对其他图书馆没有同样的问题

这是我的gradle(应用程序(模块：

apply plugin: 'com.android.application'
android {
compileSdkVersion 29
buildToolsVersion "29.0.2"
defaultConfig {
applicationId "com.example.notebook_v2"
minSdkVersion 19
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.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
implementation 'androidx.appcompat:appcompat:1.0.2'
}

这是gradle(项目(模块：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
maven { url "https://jitpack.io" }

}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

尝试实现此

implementation 'androidx.preference:preference:1.1.0'

也许你需要更新构建工具
