【问题描述】：

我在使用 Flutter 1.2.2 版和 map_view 0.0.14 版时遇到构建错误。

我尝试在 build.gradle 中使用此代码

classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2-4'

我按照这里的所有步骤https://pub.dartlang.org/packages/map_view#-readme-tab-

我有一个 api-key 但得到以下构建错误

 Error running Gradle: ProcessException: Process “C:UsersAlmoit PCDesktopMyAppMapflutter_app2androidgradlew.bat” exited
abnormally:

Configure project :map_view
WARNING: The specified Android SDK Build Tools version (27.0.3) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.2.1.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove “buildToolsVersion ‘27.0.3’” from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

FAILURE: Build failed with an exception.

What went wrong: The Android Gradle plugin supports only Kotlin Gradle plugin version 1.2.51 and higher. Project ‘android’ is using
version 1.1.2-4.

Try: Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output. Run with –scan to get full insights.

有了颤振医生，一切似乎都很好。

【解决方案1】：

在您的 /android/build.gradle 中尝试像这样增加 kotlin gradle 插件的版本：

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.0'

我在某处看到 Flutter 现在只支持 1.3+ 版本。我刚刚尝试过，现在我至少可以为 android 构建我的应用程序了。

PS：由于您使用的是旧版本的颤振，因此 kotlin 插件可能会与错误消息中提到的旧版本一起使用：

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.51'
