我有 Android 版 Kotlin 代码，Kotlin 版本是

\n

ext.kotlin_version = '1.5.20'\n

\n

我的依赖项中有这个：

\n

classpath 'com.android.tools.build:gradle:4.2.1'\n

\n

运行 flutter run --release 时出现错误，但flutter run工作正常。

\n

Exception: Unsupported Android Plugin version: 4.2.1.\n

\n

我尝试过来自SO的其他答案，例如更新Kotlin目标VM的JVM版本（我将其从8设置为11）。

\n

distributionUrl=https\\://services.gradle.org/distributions/gradle-6.7.1-all.zip我在 gradle-wrapper.properties 中也有。

\n

任何帮助是极大的赞赏。

看看你的应用程序中是否有类似下面的内容build.gradle（app/src/build.gradle）

    productFlavors {
        app_dev {
            dimension "version"
            applicationIdSuffix ".dev"
        }
        app_stg {
            signingConfig signingConfigs.debug
            dimension "version"
            applicationIdSuffix ".stg"
        }
        app_prod {
            signingConfig signingConfigs.release
            dimension "version"
        }
    }

如果确实有类似的内容，那么您需要转到 “运行” -> “编辑配置” ->“选择main.dart左侧”-> “构建风味”内，将“app_dev”放入文本框内（字符串可以是任何内容，具体取决于你的里面有什么productFlavors { ... }）

这帮助我解决了我的问题。
