多个 dex 文件定义 Lorg/springframework/http/ContentCodingType$1

Question

我测试了 android 注释框架，但是当我添加 spring-android 库时出现了一些错误。我为我的测试项目创建了 repo open_git_repo !

此刻，我在gradle控制台

我不明白这个错误，有人能解释一下这是怎么回事吗？

Answer 1

两件事：

首先声明的依赖：

//compile 'org.springframework.android:spring-android-rest-template:2.0.0.BUILD-SNAPSHOT'
 compile 'org.springframework.android:spring-android-rest-   template:1.0.1.RELEASE

我知道您注释掉了第一个依赖项，但请确保您有时没有两个。这将导致您的类路径中出现重复类并且 dex 失败。

其次，您在 libs 文件夹中有 spring android rest 模板 jar。这也会导致重复，因为您将此库称为存储库的依赖项，以及本地 libs 文件夹的依赖项。删除libs文件夹即可，完全没有必要。您应该始终使用适当的依赖管理，例如只需在您的构建脚本中声明它们，然后让 gradle 使用传递依赖项、正确的版本和依赖项冲突解决等下载它们。也删除此行：

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