运行我的第一个Java应用程序时出现InvalidModuleDescriptorException [英] InvalidModuleDescriptorException when running my first java app

问题描述

我已经开始学习Java，并在尝试运行第一个程序时遇到如下问题：

I have started learning Java and encountered a problem when trying to run my first program as given below:

public class HelloWorld {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
     System.out.println("Hello world!");
    }
}

在Eclipse Photon上，运行它时遇到此错误：

On Eclipse Photon I encounter this error when running it:

 Error occurred during initialization of boot layer
    java.lang.module.FindException: Error reading module: C:\Users\Thomas\eclipse-workspace\HelloWorld\bin
    Caused by: java.lang.module.InvalidModuleDescriptorException: HelloWorld.class found in top-level directory (unnamed package not allowed in module)

我看了看，bin目录中有我的.class文件，而 src 目录。

I looked and there is my .class file in bin directory and my .java in the src directory.

那正常吗？我该如何解决？

Is that normal? How do I fix that?

推荐答案

我遇到了同样的错误。删除 module-info.java 文件为我解决了这个问题。

I was getting the same error. Deleting the module-info.java file solved it for me.
