在构建发布版本时，我收到以下警告：

Warning: there were 11 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.

these are warnings in red in Message view :
  Warning: kotlinx.coroutines.flow.FlowKt__MergeKt: can't find referenced class kotlinx.atomicfu.AtomicBoolean

这些是我认为的11个，其中proguard只是在谈论htese警告，请请帮助

Answer 1

这是最常见的错误，因为“许多预编译的第三方库都引用了其他实际未使用并因此不存在的库。这在调试版本中工作正常，但在发行版本中，ProGuard期望所有库”，因此它可以执行适当的静态分析。

因此，您可以忽略它或在proguard-rules.pro中写上-dontwarn。

-dontwarn kotlinx.atomicfu.**

Answer 2

编写保护规则

-ignorewarnings

Answer 3

这对我有用，不知道导致错误的原因是什么，为什么科特林团队留下了这样的错误：

-dontwarn kotlinx。**
