无法解析配置':app:debugCompileClasspath'的所有工件

Question

在flutter 1.17更新后，我试图运行我的应用程序，但它显示了这个错误。flutter doctor命令工作正常。我不明白发生了什么

Answer 1

我遇到了类似的kotlin-sdk资源不可用的问题。找不到快速解决方案，但问题很可能发生在服务器端有资源的情况下。因为第二天早上，整个集会成功了。如果在此之前一切都很顺利，并且突然停止，那么您也许应该等待。

在阅读了整个分支之后，我仍然没有找到适合我的案例的解决方案，但它可能对某些人有用。https://github.com/flutter/flutter/issues/23553

我遇到了类似的问题，当我在build.gradle文件中更改以下设置时，问题得到了解决：

ext.kotlin_version = '1.3.61' //from 1.3.50
dependencies {
classpath 'com.android.tools.build:gradle:3.5.3' //from 3.5.0
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
