This project is **a collection of small and focused tutorials** - each covering a single and well defined area of development in the Java ecosystem.
|
||||||
Most of the tutorial projects are focused on the `Spring Framework` (and `Spring Security`).
|
A strong focus of these is, of course, the Spring Framework - Spring, Spring Boot and Spring Securiyt.
|
||||||
In additional to Spring, the following technologies are in focus: `core Java`, `Jackson`, `HttpClient`, `Guava`.

Building a single module
|
||||||
================================
|
====================
|
||||||
Any IDE can be used to work with the projects, but if you're using Eclipse, consider the following.
|
To build a specific module run the command: `mvn clean install -Dgib.enabled=false` in the module directory
|
||||||
|
|
||||||
- import the included **formatter** in Eclipse:
