要求：项目：app > com.google.android.libraries.places:places:2.4.0

Question

我正在尝试在我的应用程序中实现由 Google 提供支持的 PlaceAutoComplete。但我无法做到这一点...我已经在应用程序级 build.gradle 文件中实现了所需的依赖项并编写代码。但是当我运行该应用程序时，它给了我以下错误。 看到这个...

Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
> Could not find com.android.volley:volley:1.1.1.
- https://dl.google.com/dl/android/maven2/com/android/volley/volley/1.1.1/volley-1.1.1.pom
- https://repo.maven.apache.org/maven2/com/android/volley/volley/1.1.1/volley-1.1.1.pom
Required by:
     project :app > com.google.android.libraries.places:places:2.4.0
Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

我上网冲浪，但找不到任何关于这件事的帮助。

这是 Gradle 代码...

plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.fyp.biketracker"
        minSdkVersion 19
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.3.0'

    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'

    implementation 'androidx.multidex:multidex:2.0.1'

    //Circle ImageView

}

Answer 1

正如您在这里看到的：

https://mvnrepository.com/artifact/com.android.volley/volley/1.1.1

有两个存储库具有该库的特定版本：spring 存储库和 AndroidUtils 存储库。因此，您需要将其中任何一个添加到 gradle 文件的“存储库”部分，如下所示：

repositories {
        mavenCentral()
        maven {
            url "https://repo.spring.io/libs-release/"
        }
    }

这很可能是因为 Maven 中心仅包含较新的版本：

https://mvnrepository.com/artifact/com.android.volley/volley

Answer 2

在build.gradle(app)中添加volley库

implementation ("com.android.volley:volley:1.2.1")

然后修复你的错误。
