我正在尝试为我的应用程序构建gradle，但是构建失败
我到处都在寻找与此问题有关的其他问题，但无法解决。另外，我尝试过更改gradle构建工具的版本，添加了不同的lib和其他一些无法解决的问题。
pubspec.yaml
项目级别build.gradle
buildscript { repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.2.1' classpath 'com.google.gms:google-services:4.3.0' } } 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 }

您知道如何解决这个问题吗？
编辑2019-12-13 ：
从2019年12月11日发布的Flutter 1.12（稳定版）开始，Flutter样板版现在包括 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是最新的，但即使版本3.5.0也应解决此问题，如最初报告的那样。
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.propertiesFlutter样板中指定了gradle分布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。
android\gradle\wrapper\gradle- wrapper.properties
android\build.gradle
classpath 'com.android.tools.build:gradle:3.2.1'
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，然后运行flutter clean并再次尝试构建。
com.android.tools.build:gradle:3.2.1
com.android.tools.build:gradle:3.3.2
flutter clean
根据gradle发行说明，该插件和gradle的当前（2019年7月）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源gradle 5.1.1，然后将gradle插件升级到3.4.2。
android\gradle\wrapper\gradle-wrapper.properties
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，您仍然可以将插件版本设置回3.2.1，以重现该问题。
我已经与Flutter团队讨论了一个问题，以尝试更好地理解这一点，如果他们有任何具体建议，将更新此答案。
