错误：模块是使用不兼容的 Kotlin 版本编译的。其元数据的二进制版本是1.9.0，预期版本是1.7.1

Question

我的 flutter 项目遇到错误。我想将 firebase 服务添加到我的 flutter 项目中。但是，当我按照 Firebase 中的步骤将 google-json 文件添加到我的 android/app 目录并将代码依赖项添加到项目级别和应用程序级别 build.gradle 文件时。提示Kotlin版本不兼容的错误。

错误信息是

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction
   > Compilation error. See log for more details

BUILD FAILED in 50s

这是我的 android/build.gradle 文件

Answer 1

尝试更新这一行中的 Kotlin 版本：

ext.kotlin_version = '1.7.1'

元数据版本好像是1.9.0。所以你可以用 android/build.gradle 中的这一行替换该行：

ext.kotlin_version = '1.9.0'

还要确保您没有更改错误的行或除 Firebase 文档所述之外的任何其他内容。
