在模块 classes.jar 中发现重复的类 [英] Duplicated classes found in modules classes.jar

问题描述

使用 "Cxense Android SDK"，我收到了消息重复类:

Working with "Cxense SDK for Android", I'm getting the message of duplicated class:

Duplicate class android.support.v4.app.INotificationSideChannel found in modules classes.jar (**com.android.support:support-compat:27.1.1**) and classes.jar (**com.android.support:support-v4:22.2.0**)
Duplicate class android.support.v4.app.INotificationSideChannel$Stub found in modules classes.jar (com.android.support:support-compat:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.INotificationSideChannel$Stub$Proxy found in modules classes.jar (com.android.support:support-compat:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.ListFragment found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.ListFragment$1 found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.ListFragment$2 found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 
Duplicate class android.support.v4.app.LoaderManager found in modules classes.jar (com.android.support:support-fragment:27.1.1) and classes.jar (com.android.support:support-v4:22.2.0) 

这是我的应用级build.gradle配置:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.tototita.cxensetestapp"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }


    packagingOptions {
        exclude 'META-INF/LICENSE'
    }
    compileOptions {
        sourceCompatibility = '1.8'
        targetCompatibility = '1.8'
    }


}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1' 
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

     //**CXsense
     implementation 'com.cxpublic:cxense-android:1.0.1'
}

如何避免 Cxense SDK 中肯定包含的重复类?

How could I avoid this duplicated classes that are surely contained in Cxense SDK?

推荐答案

如果有重复，使用exclude:

implementation ('com.cxpublic:cxense-android:1.0.1') {
    exclude group: "com.android.support", module: "support-v4"
}

或者删除implementation 'com.android.support:appcompat-v7:27.1.1' 以支持 support-v4.
