Question

我刚刚更新了Android Studio，因此无法构建我的应用。我收到一个看起来像这样的例外：

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/LICENSE
    File1: /Users/andersvincentlund/.gradle/caches/modules-2/files-2.1/com.fasterxml.jackson.core/jackson-core/2.2.2/d20be6a5ddd6f8cfd36ebf6dea329873a1c41f1b/jackson-core-2.2.2.jar
    File2: /Users/andersvincentlund/.gradle/caches/modules-2/files-2.1/com.fasterxml.jackson.core/jackson-databind/2.2.2/3c8f6018eaa72d43b261181e801e6f8676c16ef6/jackson-databind-2.2.2.jar
    File3: /Users/andersvincentlund/.gradle/caches/modules-2/files-2.1/com.fasterxml.jackson.core/jackson-annotations/2.2.2/285cb9c666f0f0f3dd8a1be04e1f457eb7b15113/jackson-annotations-2.2.2.jar

我搜索了这种类型的错误，并建议添加：

packagingOptions {
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude '...'
}

在gradle中的android子句中。这没有任何改变（除了我的构建可能是非法的，因为我会忽略OS代码的许可？）。有没有人知道如何解决这个问题？我希望更新不会破坏代码。

编辑：

我收到了关于gradle文件的评论，因此我发布了以下全部内容：

apply plugin: 'com.android.application'     

apply plugin: 'com.neenbedankt.android-apt'

Answer 1

只需删除：

compile fileTree(include: ['*.jar'], dir: 'libs')

这

dependencies {}

jackson-core-2.2.2.jar中已存在libs/，但另一个依赖项正在尝试在外部添加它。

Answer 2

请添加以下行

packagingOptions {
exclude 'META-INF/maven/com.belerweb/pinyin4j/pom.xml'
exclude 'META-INF/maven/com.belerweb/pinyin4j/pom.properties'}

更新了Android Studio，接收DuplicateFileException
