错误：Gradle：APK打包过程中的重复文件

Question

在我的分级Android应用程序中，当我运行该应用程序时，我得到了以下错误。

错误：Gradle：APK /home/WorkSpace/MyProject/app/build/outputs/apk/app-debug-unaligned.apk打包过程中的重复文件错误：Gradle：任务'： app： pack ageDebug'执行失败。在APK META-INF/license.txt文件1： /home/.gradle/caches/modules-2/files-2.1/org.springframework.android/spring-android-rest-template/1.0.1.RELEASE/e132d929bd181941f79b0d63edafb8a86ae6fd33/spring-android-rest-template-1.0.1.RELEASE.jar文件2： /home/.gradle/caches/modules-2/files-2.1/org.springframework.android/spring-android-core/1.0.1.RELEASE/e68f0e8e4b636ee30c4de58953be38d9b72a5e3b/spring-android-core-1.0.1.RELEASE.jar中复制的重复文件

下面是我的gradle文件。build.gradle：

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.2.3'
}
}
 apply plugin: 'com.android.application'


 repositories {
  jcenter()
 }

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.example.myproject.app"
    minSdkVersion 9
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_6
    targetCompatibility JavaVersion.VERSION_1_6
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
packagingOptions {
    exclude 'META-INF/notice.txt'
}
}

 dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:gridlayout-v7:23.2.0'
compile 'com.android.support:appcompat-v7:23.2.0'

compile 'joda-time:joda-time:2.3'
compile 'com.fasterxml.jackson.core:jackson-databind:2.7.2'
compile 'com.fasterxml.jackson.core:jackson-core:2.7.2'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.7.2'
compile 'com.google.code.gson:gson:2.6.2'
compile 'com.android.support:design:23.2.0'

 }

我该如何解决这个错误？请帮助我。

Answer 1

您的构建文件中已包含以下内容：

packagingOptions {
    exclude 'META-INF/notice.txt'
}

您也可以在那里添加license.txt。

Answer 2

在PackagingOptions和依赖项中添加以下行。

packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
}

并且在依赖关系中使用如下。

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:design:23.2.0'
compile 'com.android.support:cardview-v7:23.2.0'
compile 'com.android.support:recyclerview-v7:23.2.0'
compile 'com.j256.ormlite:ormlite-core:4.48'
compile 'com.j256.ormlite:ormlite-android:4.48'
compile 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
compile('org.springframework.android:spring-android-auth:1.0.1.RELEASE') {
    exclude module: 'spring-core'
}
compile 'org.springframework.android:spring-android-core:1.0.1.RELEASE'
compile 'org.apache.commons:commons-io:1.3.2'
compile 'joda-time:joda-time:2.3'
compile 'com.fasterxml.jackson.core:jackson-databind:2.7.2'
compile 'com.fasterxml.jackson.core:jackson-core:2.7.2'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.7.2'
compile 'com.google.code.gson:gson:2.6.2'
}

我认为这将解决您的问题。
