Xamarin形式的java.exe“退出，代码为1（ProGuard的）

Question

我有问题，与我ProGuard的形式Xamarin的项目，我有以下错误：的java.exe”，代码1

和多个警告退出如：okio.Okio：找不到引用的类java.nio.file.Path

我已经尝试了许多解决方案，例如：

• 下载最新版本的Proguard的，并且在替换它规格c文件夹。
• 设置我的Java最大堆大小达到1G
• 创建我自己的proguard.cfg并设置生成操作ProguardConfiguration

这些解决方案都在工作，我已经尝试过多种清洁和建设，以及。 但有一件事很奇怪，我可以在我的链接设置为“无”而不是“仅限SDK组件”时构建我的项目。当启用ProGuard并将我的链接设置为SDK组件时，它不起作用，是否正常？

这是我的输出构建的例子：

我应该怎么办？我不知道如何解决这个问题..

Answer 1

发布您的警告error.Also在您的progaurd.pro文件中添加一些行。

-keep class org.apache.http.** { *; } 
-dontnote org.apache.http.** 
-dontwarn org.apache.http.** 
-dontwarn android.net.* 

Answer 2

尝试升级JDK

https://bugzilla.xamarin.com/show_bug.cgi?id=44187

Xamarin稳定15.2是不是稳定的，因为它应该:)

Answer 3

我用Square.Picasso库我Xamarin.Android项目没有问题并使用链接设置到SDK和用户组合。

我ProGuard的配置文件中包含的：

-dontwarn org.codehaus.** 
-dontwarn java.nio.file.** 
-dontwarn com.square.** 
-dontwarn okio.** 
-keep public class android.support.v7.widget.FitWindowsLinearLayout 
-keep public class android.support.design.widget.AppBarLayout 

你说，你在你的Android SDK有最新的ProGuard版本，所以它应该工作！
