Android:v7的编译错误支持lib 27.1.0"程序类型已存在"android.support.v7.recyclerview.extensions.ListAdapter

Question

我认为必须存在27.1.0 v7支持lib的错误,刚刚发布.更新我的项目以使用它(从26.1.0)后,我不断收到此编译错误:

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

FAILURE:构建因异常而失败.

• 出了什么问题:任务执行失败':app:transformDexArchiveWithDexMergerForRegularDebug'.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

• 尝试:使用--info或--debug选项运行以获取更多日志输出.

• 例外情况是:org.gradle.api.tasks.TaskExecutionException:任务':app:transformDexArchiveWithDexMergerForRegularDebug'的执行失败.在org.gradle上的org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:100)org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.execute(ExecuteActionsTaskExecuter.java:70)

我查看了我的项目的依赖项(./gradlew :<module>:dependencies[ <module>我的所有模块都在哪里])并验证我只有一个依赖项应该支持ListAdapter类,它就是这个:

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

我也用

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

我尝试过清洁/重建.我已经尝试使缓存无效并重新启动.我还尝试手动删除所有构建文件夹和.gradle文件夹.我也试过禁用D8,但是我的构建只是永远挂起.问题依然存在.我甚至没有使用 ListAdapter!

Answer 1

弄清楚了!原来android.arch.paging:runtime-1.0.0-alpha4-1依赖也已ListAdapter声明.将分页库更新为alpha6后,问题得以解决.

编辑由于某种原因,这个问题得到了很多关注!所以,我想我会把这个评论添加为"教人钓鱼"的那一刻.问题是:我怎么弄清楚我ListAdapter的来自哪里？答案？如果您使用的是Android Studio/IntelliJ IDEA,请按ctrl+ n开始搜索类名.你会看到这个对话框:

请注意复选框!如果您没有选中,则永远不会找到库中包含的类.通过检查,它将显示项目中每个类的出处.
