[英]REST Android Client using Spring and OAuth2 Error DexArchiveMergerException: Unable to merge dex
I have a server running and I want to connect an android client to the server with spring's oauth2. 我有一个正在运行的服务器,我想用spring的oauth2将一个android客户端连接到该服务器。 I use Android Studio.
我使用Android Studio。 My problem is related to the gradle configurations, which I don't know how it should be.
我的问题与gradle配置有关,我不知道应该怎么做。
Problem : When I run the app, I get this error: 问题 :运行应用程序时,出现以下错误:
Error:Execution failed for task':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
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. 我已经看到许多其他问题,但都遇到了同样的问题,我尝试了解决方案(例如添加
multiDexEnabled true
,清理和重建项目等),但没有一个起作用。 I think that the problem is caused because these two dependencies: 我认为问题是由以下两个原因引起的:
implementation 'org.springframework.security.oauth:spring-security-oauth2:2.2.0.RELEASE'
implementation 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
might have some common jars or something. 可能有一些普通的罐子或其他东西。 Any help would be appreciated.
任何帮助,将不胜感激。

Try this it should work for your cause. 试试这个,它应该为您的事业工作。 Go through this link to understand why we should add this line of code multiDexEnabled true
通过此链接了解为什么我们应该添加此代码行multiDexEnabled true
I finally solved the problem. 我终于解决了问题。 There were two modules that were duplicate, so I had to exclude them from the Module build.gradle file.
有两个重复的模块,因此我不得不将它们从Module build.gradle文件中排除。 What I had to do was:
我要做的是:
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'
}
