indea 运行 On java8的项目 文件位置 出错

Question

项目是 onJava8-Examples-Maven-master 码云github都有

下面代码的 Cheese.dat 这个相对路径找不到,当然其他的类中这样的相对路径都是错误的 哭

代码

import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.stream.Stream;

public class FileToWordsBuilder {
    Stream.Builder<String> builder = Stream.builder();

    public FileToWordsBuilder(String filePath)
            throws Exception {
        Files.lines(Paths.get(filePath))
                .skip(1) // Skip the comment line at the beginning
                .forEach(line -> {
                    for (String w : line.split("[ .?,]+"))
                        builder.add(w);
                });
    }

    Stream<String> stream() {
        return builder.build();
    }

    public static void
    main(String[] args) throws Exception {
        new FileToWordsBuilder("Cheese.dat").stream()
                .limit(7)
                .map(w -> w + " ")
                .forEach(System.out::print);
    }
}
/* Output:
Not much of a cheese shop really
*/

运行结果

Process finished with exit code 1

路径在这

输出class文件在这

开始时class 里面没有 Cheese.dat,后面我加了个文件夹子标记为resource,就有了

运行成功

然而在idea中还是找不到,求大佬解惑.

public static void
main(String[] args) throws Exception {
    new FileToWordsBuilder("Cheese.dat").stream()
            .limit(7)
            .map(w -> w + " ")
            .forEach(System.out::print);

这里的文件名，写成完整的绝对路径看看呢。
