Why can't I use New-> Source Folder in a newly created maven webapp project in Eclipse?

Question

I created a new maven webapp project in Eclipse, and there is a folder src / main / resources and src / main / java, so I right-click on the project folder and select "Create" → "Source folder", When I type "src / main / java ", I just get the error message:

The folder is already the source folder.

and I found in my project “Java path property” the src / main / java configuration path why does the project have such a configuration until there is such a folder as src / main / java?

Answer 3

This is absurd, but after me they worked:

• Create regular folder: Create → Folder
• Delete this folder
• Create a new source folder: Create → Source folder
