梯度- ProGuard - DuplicateClasses - NineOldAndroids

Question

我在我的项目中使用了一些库/模块。

在其中两个库中，有一个"nineoldandroids“与"-compile 'com.nineoldandroids:library:2.4.0'”in每个库/模块“一起使用！

如果我想在Android中用"Build - Generate Signed APK“来缓存APK，我总是会得到"ProGuard”错误，其中包含以下错误：

Error:Execution failed for task ':xxxxx:proguardRelease'.
> java.io.IOException: Can't write
 [F:\Projekte\Android_Studio\xxxx\build\intermediates\classes-proguard\
release\classes.jar] (Can't read 
 [F:\Projekte\Android_Studio\xxxx\build\intermediates\exploded-aar\
Android_Studio\library_SwipeListView\unspecified\libs\
nineoldandroids-2.4.0.jar(;;;;;;!META-INF/MANIFEST.MF)] 
(Duplicate zip entry [com/b/a/b.class == nineoldandroids-2.4.0.jar:com
/nineoldandroids/animation/Animator$AnimatorListener.class]))

如何解决这个错误？

SwipeListView

dependencies {
compile 'com.android.support:support-v4:20.0.0'
compile 'com.nineoldandroids:library:2.4.0'

}

NumberPickerCompat

dependencies {
compile 'com.nineoldandroids:library:2.4.0'

}

MainProject

dependencies {
compile project(':library_CalendarViewCompbat')
compile project(':library_FAB_Menu')
compile project(':library_NumberPickerCompat')
compile project(':library_ReminderDatePicker')
compile project(':library_StickyListHeaders')
compile project(':library_SwipeListView')
compile project(':library_SunDate_Picker')
compile 'com.google.android.gms:play-services:6.1.+'
compile 'com.android.support:appcompat-v7:19.1.0'
compile 'com.android.support:support-v4:20.0.0'
compile files('libs/crashlytics.jar')
compile files('libs/dashclock-api-r1.1.jar')
compile files('libs/dropbox-android-sdk-1.5.3.jar')
compile files('libs/httpmime-4.0.3.jar')
compile files('libs/json_simple-1.1.jar')

}

Answer 1

谢谢大家的回答。

问题是某些.jar文件保存在"build“文件夹中。

这是因为我已经用从Eclipse迁移了.jars，然后删除了它，并将编译添加到gradle中。但我还没有看到，在“构建”文件夹中，它们也被保存。

您可以从您的主要项目中排除一个九雄机器人传递依赖项：

dependencies {
    compile project(':library_NumberPickerCompat')
    compile(project(':library_SwipeListView')) {
        // Already present in NumberPickerCompat
        exclude group: 'com.nineoldandroids'
    }

    ...
}

请注意第二个compile依赖项上的额外括号

试试这个：

SwipeListView:

dependencies {
     compile 'com.android.support:support-v4:20.0.0'
}

NumberPickerCompat:

dependencies {

}

MainProject:

dependencies {

    //put nineoldandroids in main project
    compile 'com.nineoldandroids:library:2.4.0'

    compile project(':library_CalendarViewCompbat')
    compile project(':library_FAB_Menu')
    compile project(':library_NumberPickerCompat')
    compile project(':library_ReminderDatePicker')
    compile project(':library_StickyListHeaders')
    compile project(':library_SwipeListView')
    compile project(':library_SunDate_Picker')
    compile 'com.google.android.gms:play-services:6.1.+'
    compile 'com.android.support:appcompat-v7:19.1.0'
    compile 'com.android.support:support-v4:20.0.0'
    compile files('libs/crashlytics.jar')
    compile files('libs/dashclock-api-r1.1.jar')
    compile files('libs/dropbox-android-sdk-1.5.3.jar')
    compile files('libs/httpmime-4.0.3.jar')
    compile files('libs/json_simple-1.1.jar')
}
