为什么我的代码没有在 VisuaStudioCode 中运行？

Question

I downloaded VS code and tried to run a basic java code in it. I have already installed JDK in my system, set the environment variables too and also downloaded the red hat extension for java. The code runs smoothly in cmd prompt. But when i run the code in VS it says "File not found in the output and "Hello.java is a non project file".

The same problem is arising in C program too. What should i do to resolve this?

Answer 1

In some cases, launch.json cwd configuration is causing these errors. Could you please also share launch.json file.

This thread might help too.

Answer 2

File not found in Output.

That's because you're running tempCodeRunnerfile.java but hello.java was opened. Also you use the extension Code Runner , so the result will be shown in Output.

After cleaning java workspace, open tempCodeRunnerfile.java and click the triangle button( Run Code ) to try again.

It's recommended that using the integrated Terminal to run the code instead of Code Runner.

Hello.java is a non project file.

This couldn't be called as an error but just a warning. Press Ctrl+Shift+P to open Command Platte and choose Java: Create Java Project . Coding in project, this warning won't be shown.
