Android:v7支持lib 27.1.0的编译错误“程序类型已存在" android.support.v7.recyclerview.extensions.ListAdapter [英] Android: Compilation error with v7 support lib 27.1.0 "Program type already present" android.support.v7.recyclerview.extensions.ListAdapter

问题描述

我认为27.1.0 v7支持库

I think there must be a bug with the 27.1.0 v7 support lib, just released. After updating my project to use it (from 26.1.0), I keep getting this compilation error:

任务:app:transformDexArchiveWithDexMergerForRegularDebug失败 D8用于合并dex. 程序类型已存在:android.support.v7.recyclerview.extensions.ListAdapter

Task :app:transformDexArchiveWithDexMergerForRegularDebug FAILED D8 is used to merge dex. Program type already present: android.support.v7.recyclerview.extensions.ListAdapter

失败:构建失败，并出现异常.

FAILURE: Build failed with an exception.

• 出了什么问题: 任务':app:transformDexArchiveWithDexMergerForRegularDebug'的执行失败. com.android.build.api.transform.TransformException:com.android.tools.r8.errors.CompilationError:程序类型已存在:android.support.v7.recyclerview.extensions.ListAdapter

• What went wrong: Execution failed for task ':app:transformDexArchiveWithDexMergerForRegularDebug'. com.android.build.api.transform.TransformException: com.android.tools.r8.errors.CompilationError: Program type already present: android.support.v7.recyclerview.extensions.ListAdapter

尝试: 使用--info或--debug选项运行，以获取更多日志输出.

我已经查看了我项目的依赖项(使用./gradlew :<module>:dependencies [其中<module>是我的所有模块])，并验证了我只有一个依赖项，该依赖项应纳入支持范围 ListAdapter 类，就是这个类:

I have looked at my project's dependencies (with ./gradlew :<module>:dependencies [where <module> is all my modules]) and verified that I have only one dependency that should be pulling in the support ListAdapter class, and it is this one:

implementation "com.android.support:recyclerview-v7:27.1.0"

我也使用

configurations.all {
    resolutionStrategy {
        ...
        force "com.android.support:recyclerview-v7:27.1.0"
    }
}

我尝试清洁/重建.我尝试使缓存无效并重新启动.我还尝试过手动删除所有构建文件夹和.gradle文件夹.我也曾尝试禁用D8，但后来我的构建永久挂起.问题仍然存在.我什至没有使用 ListAdapter！

I have tried cleaning/rebuilding. I have tried invalidating caches and restarting. I have also tried manually deleting all my build folders and .gradle folders. I have also tried disabling D8, but then my build just hangs forever. The problem persists. I'm not even using ListAdapter!

推荐答案

想通了！原来 android.arch.paging:runtime-1.0.0-alpha4-1 依赖项 也已经声明了ListAdapter.将分页库更新为 alpha6 后，问题已解决.

Figured it out! Turns out the android.arch.paging:runtime-1.0.0-alpha4-1 dependency also had ListAdapter declared. After updating the paging lib to alpha6, the problem was resolved.

编辑由于某种原因，这个问题引起了很多关注！因此，我以为我会将此评论添加为教人钓鱼"的时刻.问题:我如何弄清我的ListAdapter的来源?答案?如果您使用的是Android Studio/IntelliJ IDEA，请按 ctrl + n 开始搜索类名.您会看到以下对话框:

EDIT For some reason, this question is getting a lot of attention! So, I thought I'd add this comment as a "teach a person to fish" sort of moment. The question: how did I figure out where my ListAdapters were coming from? The answer? If you're using Android Studio / IntelliJ IDEA, hit ctrl+n to begin searching for class names. You'll see this dialog:

请注意复选框！如果未选中该选项，则从不查找图书馆包含的类.选中它，它将显示项目中每个班级的出处.

Please note the checkbox! If you don't have that checked, you will never find a class included by a library. With it checked, it'll show the provenance of every class in your project.
