我测试了 androidannotations 框架，但是当我添加 spring-android 库时出现一些错误。 我为我的测试项目创建存储库 open_git_repo !

我不明白这个错误，有人可以解释一下发生了什么吗？

Answer 1

有两件事:

首先，声明的依赖项:

//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，但请确保您同时没有两个依赖项。这将导致类路径中出现重复的类，并且 dex 失败。

其次，您的 libs 文件夹中有 Spring Android Rest 模板 jar。这也会导致重复，因为您将此库作为存储库的依赖项以及本地 libs 文件夹的依赖项引用。只需删除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，例如只需在构建脚本中声明它们，然后让 gradle 使用传递依赖项、正确版本和依赖项冲突解决方案等下载它们。也删除此行:

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