目前我在build.gradle上使用这些代码行：
compile 'com.fasterxml.jackson.core:jackson-core:2.7.2' compile 'com.fasterxml.jackson.core:jackson-annotations:2.7.2' compile 'com.fasterxml.jackson.core:jackson-databind:2.7.2'
我唯一需要的是ObjectMapper,我知道它在databind包中.当我在gradle中添加这些行时,我按下同步,一切都正确.
问题是在模拟器上运行项目,Android Studio上的消息显示此错误：
Error:Execution Failed for task
‘:app:transformResourcesWithMergeJavaResForDebug’.com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files

我不知道这可能是什么.有什么建议 ？
解决方法
@H_404_34@ 加android {
...
packagingOptions {
exclude 'Meta-INF/NOTICE' // It is not include NOTICE file
exclude 'Meta-INF/LICENSE' // It is not include LICENSE file

在你的build.gradle中.
