当我尝试编译项目时，出现此错误：
找不到fragment.jar（androidx.fragment：fragment：1.0.0）。
出什么问题了？

可能为时已晚，但只需将google（）替换为
maven {
url 'https://maven.google.com/'
name 'Google'
}
在您的项目级别gradle文件中
答案 2 :(得分：-1)
我已将您的Gradle更新从 buildToolsVersion 复制到了“ 29.0.3” ，并检查了我的环境。它工作正常并且构建成功。
您的Gradle文件应为
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 29
buildToolsVersion "29.0.3"
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
defaultConfig {
applicationId "com.daggerdemo"
minSdkVersion 19
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
// externalNativeBuild {
// cmake {
// cppFlags ""
// }
// }
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
// externalNativeBuild {
// cmake {
// path "src/main/cpp/CMakeLists.txt"
// version "3.10.2"
// }
// }
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'androidx.annotation:annotation:1.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
implementation 'android.arch.persistence.room:runtime:1.1.1'
annotationProcessor 'android.arch.persistence.room:compiler:1.1.1'
kapt "android.arch.persistence.room:compiler:1.1.1"
implementation 'com.google.android.material:material:1.2.0-alpha04'
implementation 'com.google.dagger:dagger-android:2.17'
implementation 'com.google.dagger:dagger-android-support:2.17'
kapt 'com.google.dagger:dagger-android-processor:2.17'
/* Dagger2 - default dependency */
kapt 'com.google.dagger:dagger-compiler:2.17'
}
并确保您的项目级Gradle工作文件和SDK组件已更新。
这是我的项目级Gradle文件：
buildscript {
ext.kotlin_version = '1.3.61'
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.3'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
google()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
