在模块类中找到的重复类.jar

2022-09-03 08:42:43

使用Cxense SDK for Android”,我得到了重复类的消息:

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'
}

如何避免这些肯定包含在 Cxense SDK 中的重复类?


答案 1

有两种方法可以解决您的问题。

  1. 单独排除重复的依赖项implementation

  2. 通用方式从每个 s 中排除重复的依赖项implementation

让我们先来了解一下这个问题:

在这里,在你的情况下,artifact com.android.support是重复的,因为你的应用程序模块使用版本:27.1.1,而你的arctual com.cxpublic:cxense-android:1.0.1具有com.android.support的内部依赖性,使用版本:22.2.0

因此,您应该手动删除其中一个(建议删除较旧或更低版本)。让我们尝试删除它!


通过第一种方法:

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

当我们在此工件上使用我们的实现时,在我们的工件中为 com.android.support 设置排除将不会导入 support-v4 库。com.cxpublic:cxense-android:1.0.1

因此,通过手动将此块放入具有此冲突的每个工件,可以解决此问题。

通过第二种方式:

我们可以删除包含的依赖项,并用一个具有最新编号的包替换它们。在我们的例子中,它是具有不同版本的支持v4。因此,请转到app level build.gradle的Android块,并将块放在下面的块中,以从所有工件中删除重复的support-v4,以便我们可以有不同的依赖关系。

android {
    // Some other stuffs
    configurations {
        all*.exclude module: 'support-v4' // This removes all other versions of `support-v4` if gets duplicated from all the artifacts.
    }
    // Rest of other stuffs
}

答案 2

如果有重复项,请使用 :exclude

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

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