我试图在Circle CI上运行构建,但是在android kotlin中遇到了这个模棱两可的checkstyle错误,我不知道为什么会这样,以下是错误信息:
/home/circleci/repo/app/src/main/java/com/andela/mrm/util/ConvergeUIUtils.kt: (12、23):导入冲突,导入名称“ Toast”含糊不清e: /home/circleci/repo/app/src/main/java/com/andela/mrm/util/ConvergeUIUtils.kt: (14、23):导入冲突,导入名称“ Toast”不明确
下面是ConvergeUIUtils.kt
文件:

}
如何克服这种checkstyle错误?
这是错误的图片。
答案 0 :(得分:4)
您的导入具有多个名为Toast
的类。
Kotlin支持导入别名:https://kotlinlang.org/docs/reference/packages.html
import android.widget.Toast as WToast
