无法解析 com.google.android.gms:play-services-location:16.+

Question

伙计们，当我尝试在真实设备上运行我的应用程序但升级到 1.22.2 后发现该错误：

 Required by: project:app > project:location > Failed to list versions for com.google.android.gms:play-services-location. > Unable to load Maven meta-data from https://jcenter.bintray.com/com/google/android/gms/play-services-location/maven-metadata.xml. > Could not get resource 'https://jcenter.bintray.com/com/google/android/gms/play-services-location/maven-metadata.xml'. > Could not GET 'https://jcenter.bintray.com/com/google/android/gms/play-services-location/maven-metadata.xml'. > Read timed out

• 尝试：使用 --stacktrace 选项运行以获取堆栈跟踪。 使用 --info 或 --debug 选项运行以获得更多日志 output。 运行 --scan 以获得完整的见解。

我的 android\app\build.gradle：

    def localProperties = new Properties()
    def localPropertiesFile = rootProject.file('local.properties')
    if (localPropertiesFile.exists()) {
        localPropertiesFile.withReader('UTF-8') { reader ->
            localProperties.load(reader)
        }
    }
    
    def flutterRoot = localProperties.getProperty('flutter.sdk')
    if (flutterRoot == null) {
        throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
    }
    
    def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
    if (flutterVersionCode == null) {
        flutterVersionCode = '1'
    }
    
    def flutterVersionName = localProperties.getProperty('flutter.versionName')
    if (flutterVersionName == null) {
        flutterVersionName = '1.0'
    }
    
    apply plugin: 'com.android.application'
    apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
    
    def keystoreProperties = new Properties()
    def keystorePropertiesFile = rootProject.file('key.properties')
    if (keystorePropertiesFile.exists()) {
        keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
    }
    
    android {
        compileSdkVersion 28
    
        lintOptions {
            disable 'InvalidPackage'
        }
    
        defaultConfig {
            applicationId "io.bujupah.hestia"
            minSdkVersion 17
            targetSdkVersion 28
            versionCode flutterVersionCode.toInteger()
            versionName flutterVersionName
            multiDexEnabled true
        }
    
        signingConfigs {
            release {
                keyAlias keystoreProperties['keyAlias']
                keyPassword keystoreProperties['keyPassword']
                storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
                storePassword keystoreProperties['storePassword']
            }
        }
        buildTypes {
            release {
                signingConfig signingConfigs.release
            }
        }
    }
    
    flutter {
        source '../..'
    }
    
    dependencies {
        implementation 'com.google.android.gms:play-services-auth:16.0.1'
        testImplementation'junit:junit:4.12'
        testImplementation 'org.mockito:mockito-core:2.17.0'
        implementation 'com.android.support:multidex:1.0.3'
    }

我的 android\build.gradle：

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.2'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

当我运行 flutter --version 时：

Flutter 1.22.4 • channel stable • https://github.com/flutter/flutter.git Framework • revision 1aafb3a8b9 (4 months ago) • 2020-11-13 09:59:28 -0800 Engine • revision 2c956a31c0 Tools • Dart 2.10.4

我的位置插件：

 # flutter_map_marker_cluster: any
  flutter_polyline_points: ^0.2.4
  geolocator: ^6.1.1
  geocoding: ^1.0.5
  location: ^3.0.2

Answer 1

解决方案是更新

dependencies {
        com.android.tools.build:gradle:3.6.2
    }

至

dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
    }

然后将 distributionUrl 更新为

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

Answer 2

该网站因维护而停机，寻找 jcenter() 替代方案或等到他们解决问题。

Answer 3

用Jcenter()替换 Jcenter() 对我mavenCentral() 。

repositories {
    google()
    mavenCentral()  // Add this
    jcenter()    // remove this   
}

Answer 4

对于那些还没有用 AzizDev 的解决方案解决问题的人，试试这个解决方案：

也许您的某些依赖项已过时..因此，在终端中运行此命令以升级它们，然后运行项目

flutter pub upgrade --major-versions

Answer 5

我尝试了所有解决方案，但对我没有任何效果。 解决此问题的唯一方法是关闭 WIFI 并运行项目。

Answer 6

以下更改对我有用

//Project level build.gradle

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.+'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.10'
    }
}


//App level build.gradle

configurations.all {
    resolutionStrategy {
        force 'com.google.android.gms:play-services-location:16.0.0'
    }
}
dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.google.firebase:firebase-analytics:17.2.2'
    implementation 'com.google.android.gms:play-services-location:16.0.0'//add this line 
}

Answer 7

只需检查 flutter 项目中的 gradle 版本，如下所示：

/android/build.gradle：

dependencies {
    classpath 'com.android.tools.build:gradle:4.1.3'
    ...
}

/android/gradle/wrapper/gradle-wrapper.properties：

...
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

Answer 8

我也有同样的问题。 请帮我解决它。 我已经尝试使用上述所有方法，但它没有

Answer 9

有同样的问题。 我尝试了开发人员说的许多解决方案。 但是，还是有问题。 现在，我删除了位置：^3.0.2。 现在工作正常。

Answer 10

Go to your.pub-cache/hosted/pub.dartlang.org/ go to your plugin and then go to android folder/ change version of your com.google.android.gms:play-services-location:16.+ to specific版本。 然后它将完美运行

注意：windows 中的 Your.pub/cache 文件夹路径应该不同，如果隐藏，您还需要取消隐藏.pub-cache 文件夹
