Android 生成已签名的apk时生成失败

如果我为调试版本启用r8/proguard，则我的应用程序构建不会出现任何错误。但是如果我试图生成一个签名的apk，那么构建就会失败，尽管我已经从okhttp和改型的github repo中为proguard/r8添加了规则

当我使用--info运行它时，Gradle错误日志

我的proguard-rules.pro文件：

-dontobfuscate
-keep public class bd.edu.daffodilvarsity.classmanager.common.models.* { *; }

这是R8中的一个错误-与此密切相关。它应该在R8编译器的版本2.2.53中修复。该修复程序正在studio中运行，应不晚于studio 4.2 RC1。可以通过将以下内容添加到顶级build.gradle文件来使用版本2.2.53：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.4.21'
    repositories {
        google()
        jcenter()
        maven {
            url "http://storage.googleapis.com/r8-releases/raw/master"
        }

这看起来像是R8编译器的问题，可能与相同，因此请继续关注。您可以尝试切换到R8版本2.1.86或2.2.51（您已经有了版本2.1.75的特定参考，但AGP4.1.2实际上与2.1.86捆绑在一起）。否则，如果您可以共享一个，这将有助于查找问题。你可以私下和我分享sgjesse@google.com及mkroghj@google.com.I尝试降级AGP并在不同的R8版本之间切换，但没有解决我的问题。正如您所提到的，我已经创建了编译器转储。如果你看一看，那就太慷慨了。我已经在谷歌硬盘上分享了这两封邮件。谢谢你的帮助。我们（R8团队）可以重现这个问题，当我们有更多信息时会回来。请关注更新。这看起来像是R8编译器的问题，可能与相同，因此请继续关注。您可以尝试切换到R8版本2.1.86或2.2.51（您已经有了版本2.1.75的特定参考，但AGP4.1.2实际上与2.1.86捆绑在一起）。否则，如果您可以共享一个，这将有助于查找问题。你可以私下和我分享sgjesse@google.com及mkroghj@google.com.I尝试降级AGP并在不同的R8版本之间切换，但没有解决我的问题。正如您所提到的，我已经创建了编译器转储。如果你看一看，那就太慷慨了。我已经在谷歌硬盘上分享了这两封邮件。谢谢你的帮助。我们（R8团队）可以重现这个问题，当我们有更多信息时会回来。请关注更新。
