Scala错误：无法在Scala IDE和Eclipse中找到或加载主类 [英] Scala Error: Could not find or load main class in both Scala IDE and Eclipse

问题描述

这是我的问题，我知道有很多类似问题的答案，但是在我尝试之后它们都没有奏效。我正在使用Scala IDE 4.6和eclipse Oxygen来运行代码，所有这些错误都失败了。

Here is my problem, I know there are lots of answers for similar questions, however none of them worked after I tried. I'm using both Scala IDE 4.6 and eclipse Oxygen to run the code and all failed on this error.

这是我的scala编译器配置：

Here's my scala compiler configuration:

这是我的运行配置：

这是我的代码，文件结构和错误显示在控制台中：

Here is my code, file structure and error showed in console:

以下是信息问题控制台：

从在线答案，我已经尝试在构建之前清理项目，我也尝试了所有版本的JVM和Scala编译器，所有这些都无济于事。

From online answer, I have already tried to clean the project before building, I also tried all the versions of JVM and Scala compiler, all of those didn't help.

代码直接从在线课程代码导入，所以我相信不应该有任何错误代码。

The code was directly import from a online course code, so I believe there shouldn't be any errors in the code.

推荐答案

我认为这应该是你的文件夹结构

I think this should be your folder structure

Scala0
└── src
    └── main
        └── scala
            └── com.ks.sparkscala
                └── FriendsByAge

在你的情况下，在src中创建一个文件夹main / scala并将包复制到里面它。

In your case create a folder main/scala inside src and copy the package inside it.
