错误描述

今天在android Studio项目中加入了jackson的开发包，编译运行时候，引发了如下的错误：

Error:Execution failed for task ‘:app:transformResourcesWithMergeJavaResForDebug‘.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: 

Duplicate files copied in APK META-INF/NOTICE
    File1: D:\Code\XTCKuwoWatch\app\libs\jackson-core-2.4.4.jar
    File2: D:\Code\XTCKuwoWatch\app\libs\jackson-databind-2.4.4.jar

解决办法

在build.gradle文件中加入下面这段代码

packagingOptions {
        exclude ‘META-INF/LICENSE‘
        exclude ‘META-INF/NOTICE‘
    }

• 没修改前的build.gradle文件

apply plugin: ‘com.android.application‘


android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.oyp.csdn"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘
        }
    }
}

dependencies {
    compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])
}

• 修改后的build.gradle文件

apply plugin: ‘com.android.application‘


android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    packagingOptions {
        exclude ‘META-INF/LICENSE‘
        exclude ‘META-INF/NOTICE‘
    }

    defaultConfig {
        applicationId "com.oyp.csdn"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘
        }
    }
}

dependencies {
    compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])
}
