REST Android 客户端使用 Spring 和 OAuth2 错误 DexArchiveMergerException:无法合并 dex [英] REST Android Client using Spring and OAuth2 Error DexArchiveMergerException: Unable to merge dex

问题描述

我有一个服务器正在运行，我想使用 spring 的 oauth2 将一个 android 客户端连接到服务器.我使用安卓工作室.我的问题与gradle配置有关，我不知道应该如何.

I have a server running and I want to connect an android client to the server with spring's oauth2. I use Android Studio. My problem is related to the gradle configurations, which I don't know how it should be.

问题:当我运行应用程序时，出现此错误:

Problem: When I run the app, I get this error:

Error:Execution failed for task':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

我已经看到许多其他问题与相同的问题，我尝试了解决方案(例如添加 multiDexEnabled true、清理和重建项目等)，但没有一个奏效.我认为问题是由这两个依赖引起的:

I have seen many other questions with the same problem, I tried the solutions (like adding multiDexEnabled true, clean and rebuild the project etc.) but none of them worked. I think that the problem is caused because these two dependencies:

implementation 'org.springframework.security.oauth:spring-security-oauth2:2.2.0.RELEASE'
implementation 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'

可能有一些常见的罐子什么的.任何帮助将不胜感激.

might have some common jars or something. Any help would be appreciated.

推荐答案

我终于解决了这个问题.有两个模块是重复的，所以我不得不从 Module build.gradle 文件中排除它们.我必须做的是:

I finally solved the problem. There were two modules that were duplicate, so I had to exclude them from the Module build.gradle file. What I had to do was:

compile('org.springframework.android:spring-android-rest-template:2.0.0.M3') {
    exclude module: 'spring-android-core'
}

compile('org.springframework.security.oauth:spring-security-oauth2:2.3.0.RC1'){
    exclude module: 'spring-web'
}
