Eclipse Source Folders vs Packages
code-organization, eclipse, organization, package
Solution
Source folders are useful to build several artefacts (jar files, for example) from a given project. The most common usage is to have a source folder for the classes of an application, and another one for the classes of the tests of the application.
Packages and source folders are an orthogonal notion. The package of a class is what is declared after the `package` keyword in the class, whatever its source folder is. Source folder are simply a way to segregate source files inside your project.
Problem
In Eclipse, within a project, when and why is it advantageous to create multiple source folders, instead of having multiple packages within the default source folder (src). How do source folders behave differently from packages?
