ProGuard：“java.exe”在添加 ModernHTTPClient 后以代码 1 退出

Posted 2023-04-15

【中文标题】ProGuard：“java.exe”在添加 ModernHTTPClient 后以代码 1 退出

【英文标题】：ProGuard: "java.exe" exited with code 1 after adding ModernHTTPClient

【发布时间】：2017-09-09 16:11:52

【问题描述】：

在Xamarin.Forms 项目中，我添加了ModernHTTPClient 库，现在ProGuard 步骤因错误而中断：

C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\android\Xamarin.Android.Common.targets(2025,3): error MSB6006: "java.exe" exited with code 1.

（以前，我在使用 ProGuard 时遇到了一些问题，但通过将 ProGuard 升级到最新版本，我能够在针对 Android 7.1 的情况下使其正常工作。）

我尝试将 Java 堆大小增加到 1G，但没有效果。

如果您对如何解决此问题有任何想法，请告诉我。谢谢。

【问题讨论】：

不确定该错误，但我建议不要再使用现代 HTTP 客户端。我曾经专门使用它，但现在 Xamarin 允许您在没有库的情况下获得使用本机消息处理程序的相同功能。我也停止使用它，因为当网络连接丢失时，Android 上来自库的无法捕获的异常等等。这些问题已在 GitHub 页面上提出，但实际上都没有得到修复。

我想这说明了一切； warning : there were 14 unresolved references to classes or interface. You may need to add missing library jars or update their versions. If your code works fine without the missing classes, you can suppress the warnings with '-dontwarn' options.

杰拉德在做某事。但是实际错误是2> java.io.IOException: Please correct the above warnings first.，这意味着您需要修复上面的警告或禁止它们。

【参考方案1】：

听起来您需要做的就是将proguard.cfg 文件添加到您的项目中，并将构建操作设置为ProguardConfiguration 以删除任何警告并保留任何必要的类，例如：

# General Android
-dontwarn org.apache.http.**
-dontwarn android.net.http.AndroidHttpClient

# Android Support Library
-keep class android.support.multidex.MultiDexApplication
-keep class android.support.v4.**
-keep class android.support.v7.** 
    public *;


# Google Play Billing
-keep class com.android.vending.billing.**

# Google Play Services
-dontwarn com.google.android.gms.internal.*
-keep class * extends java.util.ListResourceBundle 
    protected java.lang.Object[][] getContents();

【讨论】：

做到了！谢谢。

不是问题 proguard 如果您以前从未做过，设置起来可能会相当棘手。

@Nick 我有同样的错误，但我第一次使用 proguard 无法解决请帮助！

如果您将日志记录更改为详细并构建它应该在输出中向问题包/名称发出警告，您需要添加一个例外
