的ProGuard：「java.exe的」與代碼1退出添加ModernHTTPClient

在Xamarin.Forms項目後，我加入ModernHTTPClient庫現在用錯誤ProGuard的步遊：的ProGuard：「java.exe的」與代碼1退出添加ModernHTTPClient

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.

（在此之前，我有一些問題使用ProGuard，但通過將ProGuard升級到最新版本，可以將其安裝到Android 7.1上。）

我試着將Java堆大小增加到1G，但沒有任何效果。

請讓我知道如果你有任何想法如何解決這個問題。謝謝。

不知道這一點錯誤，但我建議不要再使用現代HTTP客戶端。我使用它獨佔使用它，但現在Xamarin允許您獲得使用本地消息處理程序而不使用庫的相同功能。當網絡連接丟失時，我也停止使用它，因爲來自庫的Android上不可捕捉的異常來自其他事物。這些問題已在GitHub頁面上提出，但它們都沒有實際修復。 – hvaughan3

我認爲這說明了一切;警告：有14個未解決的對類或接口的引用。您可能需要添加缺少的庫罐或更新其版本。如果你的代碼工作正常，沒有缺失的類，你可以用'-twtwarn'選項來禁止警告。「＃ –

傑拉爾德正在進行一些工作。但是實際的錯誤是'''2> java.io.IOException：請先糾正上述警告。「這意味着您需要修正上面的警告或禁止它們。 –

這聽起來像所有你需要做的是一個proguard.cfg文件添加到您的項目設置爲ProguardConfiguration，以消除任何警告，並保留任何必要的類，例如生成操作：

# 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(); 
}

這樣做！謝謝。 – erdinger

沒有問題如果你以前從未做過，proguard的設置可能會非常棘手。 – Nick

@Nick我有同樣的錯誤，但我無法第一次使用proguard解決它幫助請！ –

的ProGuard：「java.exe的」與代碼1退出添加ModernHTTPClient
