我正在尝试导出 apk,我想启用 Proguard,但它抛出了错误。我阅读了很多答案并尝试了但没有奏效。出现以下错误:

Warning:Exception while processing task java.io.IOException: java.lang.NullPointerException 
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease

堆栈跟踪:

:app:transformClassesAndResourcesWithProguardForRelease
ProGuard, version 5.2.1
Warning: Exception while processing task java.io.IOException: java.lang.NullPointerException
:app:transformClassesAndResourcesWithProguardForRelease FAILED

FAILURE: Build failed with an exception.


* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> Job failed, see logs for details

* Try:
Run with --info or --debug option to get more log output.


* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.

如果有人有任何解决方案,请在这里分享。

最佳答案

将以下内容添加到您的 ProGuard 规则中

-ignorewarnings

-keep class * {
public private *;
}

并重建您的项目。
