当我构建android项目时，它显示“重复类”异常，
工作人员提出了1个异常：java.lang.RuntimeException： java.lang.RuntimeException： 在模块classes.jar（android.arch.core：core：1.0.0-alpha1）和classes.jar（android.arch.core：runtime：1.1.1）中找到重复的android.arch.core.executor.DefaultTaskExecutor类br /> 在模块classes.jar（android.arch.core：core：1.0.0-alpha1）和classes.jar（android.arch.core：runtime：1.1.1）中找到重复的android.arch.core.executor.TaskExecutor类/ strong>
我如何找到并修复哪些lib在项目中使用重复类？

您需要排除Arch Jar。首先检查重复项的来源。如果使用gradle任务打印依赖关系树，则可以看到它：
./gradlew -q dependencies app:dependencies --configuration compile
然后像滑行一样排除旧的弓形罐子，但要正确排除，例如：
implementation ('android.arch.persistence.room:runtime:1.0.0-alpha1') {
exclude group: "android.arch.core"
}

您可以在各处使用“搜索”对话框（两次按下Shift键打开的对话框）。
只需复制类名并将其粘贴到搜索对话框中，它将在下拉列表中显示结果。您可以浏览结果并检查是否有重复的条目，班级完整路径将显示在班级名称旁边，以便您可以找到相关的库并将其安全地从任何库中排除。
