[英]Fail to run Java code (by opening a project) with Intellij IDEA
I am new to the IDE.我是 IDE 的新手。 I have installed Java SE Development Kit 13.0.1 and set it as my JDK installation.
我已经安装了 Java SE Development Kit 13.0.1 并将其设置为我的 JDK 安装。
I opened a project (.java file) and the code was successfully shown.我打开了一个项目(.java 文件)并成功显示了代码。 But the main run is greyed out and I can't run my code.
但是主要运行是灰色的,我无法运行我的代码。
May I know how can I solve it?我可以知道我该如何解决吗? Thanks for your help!
谢谢你的帮助!
I think, your source folder is not specified as a source folder.我认为,您的源文件夹未指定为源文件夹。 To fix this, do the following:
要解决此问题,请执行以下操作:
Go to modules(in the Project Structure
menu)转到模块(在
Project Structure
菜单中)
Select your source folder(likely src
)选择您的源文件夹(可能是
src
)
Click on source folder
above it.单击其上方的
source folder
。
The source directory should be blue.源目录应该是蓝色的。
Save the changes(click ok to close it)保存更改(点击确定关闭)
It should work.它应该工作。
I'm not so sure about that (its kind of a bug that sometimes happens), but try putting your mouse on the "main" in the main function and then hit ctrl + Enter and choose run.我对此不太确定(有时会发生这种错误),但是尝试将鼠标放在主函数中的“main”上,然后按 ctrl + Enter 并选择运行。
hope this helps希望这可以帮助
