问题描述
我收到了可怕的java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex错误.堆栈跟踪将根本原因显示为:
I get the dreaded java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex error. The stack trace shows the root cause as:
Caused by: com.android.dex.DexException: Multiple dex files define Landroid/support/v7/recyclerview/extensions/ListAdapter;
at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:661)

根本原因是什么?
推荐答案
最有可能，您正在尝试使用以下两个依赖项:
Most likely, you are attempting to use these two dependencies:
implementation "android.arch.paging:runtime:1.0.0-alpha5"
implementation "com.android.support:recyclerview-v7:27.1.0"
冲突的类(android.support.v7.recyclerview.extensions.ListAdapter)从分页runtime移到了recyclerview-v7 ...，但是只有分页runtime中的1.0.0-alpha6或更高版本.使用1.0.0-alpha5和支持库的27.1.0，您将在两个地方得到相同的类.
The conflicting class (android.support.v7.recyclerview.extensions.ListAdapter) moved to recyclerview-v7 from the Paging runtime... but only with 1.0.0-alpha6 or higher of the Paging runtime. With 1.0.0-alpha5, coupled with 27.1.0 of the Support Library, you get the same class in both places.
相反，请迁移至:
implementation "android.arch.paging:runtime:1.0.0-alpha6"
implementation "com.android.support:recyclerview-v7:27.1.0"
