If you want to read file from src/main/resources directory you should use Source.fromResource method, so try this:

(如果要从src/main/resources目录读取文件，则应使用Source.fromResource方法，因此请尝试以下操作：)

Source.fromResource("sample.txt")(Codec.UTF8)

Update

(更新资料)

In your case you have to use either Source.fromFile("src/main/resources/sample.txt") or Source.fromFile("sample.txt") if you put your file in root project directory

(如果您将文件放在根项目目录中，则必须使用Source.fromFile("src/main/resources/sample.txt")或Source.fromFile("sample.txt"))
