无法确定任务'：app：compileDebugJavaWithJavac Flutter VS 的依赖关系

Question

项目文件夹完美。错误在 visual studio、flutter 文件或其他地方。

我知道有旧版本的 VisualStudio 和 Flutter，但我的项目在这些版本中运行良好。 visual studio错误更新出现错误，我将其降级到我以前使用的版本但错误仍然存在

错误说明：

失败：构建失败，出现异常。

出了什么问题：无法确定任务“:app:compileDebugJavaWithJavac”的依赖项。

修改build.gradle文件如下

之前

 repositories {
        google()
        jcenter()
 }

之后

 repositories {
        google()
        mavenCentral()
 }

祝你好运。
