android - 收缩过程中发现警告，请使用-dontwarn或-ignorewarnings抑制它们

Question

如何解决这个错误？我们尝试清理并重建，重新启动 android studio，但没有用。错误:任务 ':app:transformClassesWithAndroidGradleClassShrinkerForDebug' 执行失败。

Warnings found during shrinking, please use -dontwarn or -ignorewarnings to suppress them.

有时(实际上是大多数时候)Proguard 很偏执，因为它找不到一些引用。通常，在您确定已正确实现它的情况下，可以忽略它的警告。

要修复您的错误，您需要忽略像这样的 com.yongchun 警告:添加到您的 Proguard 规则 -dontwarn com.yongchun.**
