没有在Spring Tool Suite中下载依赖项

Question

I am creating a Spring Starter Project using Spring Tool Suite. I selected JPA, Web and Derby Database dependencies. When my new project is created the src folder displays a "?" mark as shown in the screenshot. What am I missing? Why the question mark?

Answer 1

Note that there's an entry called "Maven Dependencies" right above those folders. Maven doesn't download dependencies into your project, it puts them in your local repository (generally ~/.m2/repository ).

The question marks have nothing to do with dependencies--they're Eclipse's indication that you haven't added those entries to source control. (Contrast with the mvnw and POM entries, which have a stylized disk pack to show they are in source control.)
