我想在我的项目中使用Proguard，但我在尝试构建时收到java.exe错误。
"java.exe" exited with code 1.
我尝试过增加堆大小并创建一个proguard.cfg文件，但没有成功。
当我关闭Proguard时，我可以构建项目，所以我相信这是问题所在。
有什么帮助吗？
编辑：添加看起来相关的输出。我看到了一个例外和许多警告，但我不确定如何开始解决这些问题。

答案可以在这个线程中找到。
Xamarin.Android Proguard-不支持的类版本号52.0
您还需要将以下文件从旧proguard复制到新文件夹中。
- proguard-android.txt
- proguard-android-optimize.txt
- proguard-project.txt
尝试在Proguard.cfg文件中添加以下行：
-dontwarn okio.**
如果这没有帮助，还可以添加以下内容：
-dontwarn org.jcodec.codecs.h264.**
-keep class org.jcodec.codecs.h264.** {*;}
我所要做的就是将proguard升级到这里的最新版本：https://sourceforge.net/projects/proguard/files/
在macOS上，如果使用Xamarin Studio/View Studio for Mac，Proguard目录的位置在这里：
/Users/your_username/Library/Developer/Xamarin/android-sdk-macosx/tools/proguard/bin
这可能会对某人有所帮助。我的问题是proguard.cfg编码，如下所述：https://developer.xamarin.com/guides/android/deployment，_testing，_and_metrics/proguard/#故障排除
尝试在notepad++中打开cfg文件。如果编码为"以UTF-8 BOM编码"，则需要使用"以UTF-8编码"保存文件
