【中文标题】为啥我的 Xamarin.Android 项目不能在启用 Proguard 的情况下构建：“java.exe”退出代码 1【英文标题】：Why won't my Xamarin.Android project build with Proguard enabled: "java.exe" exited with code 1为什么我的 Xamarin.Android 项目不能在启用 Proguard 的情况下构建：“java.exe”退出代码 1 【发布时间】：2016-08-27 16:44:29 【问题描述】：我想在我的项目中使用 Proguard，但是当我尝试构建时收到 java.exe 错误。
"java.exe" exited with code 1.
我已尝试增加堆大小并创建proguard.cfg file as outlined here,，但没有成功。
我可以在关闭 Proguard 时构建项目，所以我确信这是问题所在。
有什么帮助吗？
编辑：添加看起来相关的输出。我看到一个异常和许多警告，但我不确定如何着手解决这些问题。

【问题讨论】：
在控制台输出下查看此错误的更多信息。例如，它可能是丢失的文件或错误的文件名。java.io.IOException: Please correct the above warnings first ...如果你想让错误消失，你必须修复它们
SDK 管理器是否建议任何更新？您是否有可用的 jdk 更新或不一致的版本？只是建议，因为我不知道；）
你好，朋友。我和你有完全相同的错误。你能解决吗？
您能解决这些问题吗？特别是“对类或接口的 20 个未解决的引用”？
【参考方案1】：
答案可以在这个帖子中找到。
Xamarin.Android Proguard - Unsupported class version number 52.0
您还需要将以下文件从旧的 proguard 复制到新文件夹中。
proguard-android.txt proguard-android-optimize.txt proguard-project.txt【讨论】：
【参考方案2】：尝试在 Proguard.cfg 文件中添加以下行：
-dontwarn okio.**
如果这没有帮助，也添加这些：
-dontwarn org.jcodec.codecs.h264.**
-keep class org.jcodec.codecs.h264.** *;
【讨论】：
【参考方案3】：我所要做的就是将 proguard 升级到最新版本：https://sourceforge.net/projects/proguard/files/
在 macOS 上，如果使用 Xamarin Studio/Visual Studio for Mac，Proguard 目录的位置在这里：
/Users/your_username/Library/Developer/Xamarin/android-sdk-macosx/tools/proguard/bin
【讨论】：
【参考方案4】：这可能对某人有所帮助。我的问题是这里描述的 proguard.cfg 编码： https://developer.xamarin.com/guides/android/deployment,_testing,_and_metrics/proguard/#Troubleshooting
尝试在 notepad++ 中打开 cfg 文件。如果编码是“Encode in UTF-8 BOM”，则需要使用“Encode in UTF-8”保存文件
【讨论】：
【参考方案5】：您能否尝试在项目属性/选项中将 Java 堆大小增加到 1G
