我正在尝试通过Proguard运行我的Android应用程序，但这一直在出现：
Warning:Exception while processing task java.io.IOException: Can't write [C:\Users\Aliaksei\AndroidStudioProjects\SignOutSystem\app\build\intermediates\transforms\proguard\debug\jars\3\1f\main.jar] (Can't read [D:\Users\Aliaksei\.android\build-cache\f7a6034d02d095f18cc21950f131d07fa78b41c0\output\jars\classes.jar(;;;;;;**.class)] (Duplicate zip entry [android/support/v4/os/j.class == classes.jar:android/support/v4/os/ResultReceiver$MyResultReceiver.class]))
我知道这意味着android.support.v4在某处被声明了两次，所以我尝试将exclude group: 'com.android.support', module: 'support-v4'添加到可能包含它的任何可能的依赖项中，但这并不起作用，即使经过清洁和重建。
认为我一定错过了某个地方的依赖，我继续将它添加到所有内容（Overkill），但这仍然没有奏效。
搜索周围，我在类似的帖子中找到了这个片段，并在android部分添加了这个：
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
我已经用尽了想法并且寻找答案似乎把我带到了我已经尝试过的事情上。我失踪了什么？

问题是butterknife使用更高的支持版本（25.1.0）编译，因此您可能希望降级butterknife或将所有支持库移至25.1.0 < / p>
我已将butterknife降级为8.0.1：
dependencies {
compile('com.google.api-client:google-api-client-android:1.22.0') {
exclude module: 'httpclient'
}
compile('com.google.apis:google-api-services-sheets:v4-rev19-1.22.0') {
exclude module: 'httpclient'
}
compile 'com.google.android.gms:play-services-identity:9.2.0'
compile 'com.google.android.gms:play-services-auth:9.2.0'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:percent:23.4.0'
compile 'com.squareup.okhttp3:okhttp:3.3.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'
compile 'com.squareup.okio:okio:1.8.0'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'net.sf.biweekly:biweekly:0.4.6'
compile 'com.github.tibolte:agendacalendarview:1.0.4'
compile 'com.7heaven.widgets:segmentcontrol:1.14'
compile 'com.survivingwithandroid:weatherlib:1.6.0'
compile 'com.survivingwithandroid:weatherlib_okhttpclient:1.6.0'
compile files('libs/FDxSDKProAndroid.jar')
debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5'
releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5'
testCompile('com.squareup.leakcanary:leakcanary-android-no-op:1.5')
compile 'com.jakewharton:butterknife:8.0.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.0.1'
}
然后在proguard.pro处理警告：
-keep class com.fasterxml.** { *; }
-dontwarn com.fasterxml.**
-keep class biweekly.io.json.** { *; }
-dontwarn biweekly.io.json.**
-dontwarn java.lang.invoke**
-dontwarn sun.misc.Unsafe
-dontwarn okio.**
请注意，我还启用了multidex以便成功构建：我已将multiDexEnabled true添加到defaultConfig
