Question

我最近安装了Java JDK 12.0.1，并将 JAVA HOME 的环境变量设置为

C：\ Program Files \ Java \ jdk-12.0.1 \ jdk-12.0.1

并添加了一个新的路径变量并将其设置为

C：\ WINDOWS \ system32; C：\ WINDOWS; C：\ Program Files \ Java \ jdk-12 \ bin

然后，我从Eclipse网站安装了Java开发人员专用的Eclipse IDE并启动了它。我继续制作一个新的Java项目，最终结果是它没有创建一个带有（默认包）和.java文件等的Java项目，而是仅创建了一个模块。

我有图片，并会尝试在此处显示为附件（如果可能）或指向在Imgur上上传的图片的链接。

非常感谢您的帮助。全面披露：我（可能也是）对编码和所有这些都是新的。

我尝试多次卸载Eclipse和Java JDK，但是没有运气。

目前没有可显示的代码，但这是一些图片...

第1步

第2步

第3步

第4a步（如果选择了创建）

第4b步（如果选择了“不创建”）

这是应该如何创建的（我之前创建了一个较旧的项目）

https://imgur.com/a/1uivKUJ

预期结果：创建新的Java项目。实际结果：没有创建新的Java项目。

Eclipse不是创建Java项目，而是仅创建模块
