我正在尝试为我的应用构建gradle，但是构建失败
我已经围绕其他一些与此问题相关的问题进行了调查，但我无法解决。 另外，我尝试过更改gradle构建工具的版本，添加了不同的lib和一些其他无法解决问题的内容。

您知道如何解决此问题吗？

编辑2019-12-13 ：
自2019年12月11日发行的Flutter 1.12（稳定版）起，Flutter样板now includes gradle发行版5.6.2和插件版本3.5.0有望使这成为一个历史性的SO问题。插件版本3.5.3是最新版本，但即使版本3.5.0也应解决最初报告的问题。
原始答案：
这似乎是由Flutter样板指定了gradle插件的旧版本引起的。我仍然不清楚pubspec.yaml / lock中的Flutter软件包更新是否触发了该问题，我回滚了一些方法，但它仍然存在。
由于某种原因，这会影响我的Windows 10系统，但不会影响我的Mac开发环境。据我所知，它们都是最新的（Flutter 1.7.8 + hotfix.4），并且在所有版本的相同版本上。因此，在下面的注释中使用了路径分隔符。
在android\gradle\wrapper\gradle-wrapper.properties中，Flutter样板指定了gradle发行版4.10.2，它支持的插件版本最高为3.3.2。但是，android\build.gradle仅取决于插件版本3.2.1（classpath 'com.android.tools.build:gradle:3.2.1'）。目前尚不清楚为什么Flutter样板内部不一致。
要解决此问题，请更改com.android.tools.build:gradle:3.2.1 => com.android.tools.build:gradle:3.3.2，运行flutter clean，然后再次尝试构建。
根据gradle release notes，当前（2019年7月）的插件和gradle版本分别为3.4.2和5.1.1。我不知道Flutter是否正式支持此版本，尽管它似乎可以在我的项目中使用，而且干净的构建速度明显更快。发行说明涵盖了3.2.x => 3.3.x => 3.4.x的部分更改。
要升级到当前版本，请编辑android\gradle\wrapper\gradle-wrapper.properties以获取gradle 5.1.1的源代码，然后就可以将gradle插件升级到3.4.2。
gradle-wrapper.properties：
distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip
build.gradle：
classpath 'com.android.tools.build:gradle:3.4.2'
请注意，一旦使用gradle 5.1.1，您仍可以将插件版本设置回3.2.1，以重现该问题。
我已经与Flutter团队合作an issue，以试图更好地理解这一点，如果他们提出任何具体的建议，我们将更新此答案。

如果仍然遇到问题，请确保已在Android Studio的SDK工具中启用了Google Play服务。
将Google服务从classpath 'com.google.gms:google-services:4.3.0'更改为classpath 'com.google.gms:google-services:4.2.0'后，我仍然遇到错误。
启用Google Play服务后，该错误已修复。

我更改了project / build.gradle文件，如下所示：
// ...
dependencies {
classpath 'com.android.tools.build:gradle:3.3.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.2'
// ...
}
在这里，我的项目使用kotlin-gradle-plugin，它依赖于"$kotlin_version"。并且Android Gradle插件仅支持Kotlin Gradle插件1.3.0及更高版本。因此，我在同一“ build.gradle ”文件上更改了kotlin_version的值。
只需更改
ext.kotlin_version = '1.2.71'
到
ext.kotlin_version = '1.3.0'
而且，您还需要转到“ android / gradle / wrapper / gradle-wrapper.properties”文件，并将其更改为：
distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.3-all.zip
现在，运行“ flutter clean ”，然后运行“ flutter run ”命令。效果很好！

我有同样的问题。我认为，如果您使用这些依赖项的版本，它应该可以工作。
PATH: <project-folder>/android/build.gradle
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.google.gms:google-services:4.0.1'
}
