伙计们，当我试图在真实设备上运行我的应用程序时，但在升级到1.22.2后发现了错误：
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输出。使用--scan运行以获得完整的见解

当我运行flutter时——版本：
Flutter 1.22.4•通道稳定•https://github.com/flutter/flutter.git框架•修订1afb3a8b9(4个月前(•2020-11-13 09:59:28-0800发动机•修订2c956a31c0工具•飞镖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
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
以下更改对我有效
//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
}
用mavenCentral()替换Jcenter()对我有效。
repositories {
google()
mavenCentral() // Add this
jcenter() // remove this
}
对于REACT-NATIVE用户：在您的android文件夹中，在...androidbuild.gradle文件中进行此更改。
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：
也许你的一些依赖关系已经过时了。。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
网站已停止维护，请寻找jcenter((替代方案或等待他们解决问题。
转到你的.pub cache/hosts/pub.dartlang.org/转到你自己的插件，然后转到android文件夹/更改你的com.google.android.gms:play services location:16.+到特定版本。然后它将完美地工作
注意：您的.pub/cache文件夹路径在窗口中应该不同，如果.pub缓存文件夹被隐藏，您还需要取消隐藏
只需检查flutter项目中的渐变版本，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
如果所有答案都不适用，下面是我解决问题的方法：(React Native(
- 完全删除node_modules
- 重新安装纱线或npm
- 在你的Project/android/(./gradlew-Clean(中清理你的android构建
- 在Android工作室中，点击同步您的项目文件(带蓝色箭头的大象(
- 重新生成
就是
