This project is **a collection of small and focused tutorials** - each covering a single and well defined area of development in the Java ecosystem.
A strong focus of these is, of course, the Spring Framework - Spring, Spring Boot and Spring Security.
In additional to Spring, the modules here are covering a number of aspects in Java.
In addition to Spring, the modules here cover a number of aspects of Java.
Profile based segregation
====================
We are using maven build profiles to segregate the huge list of individual projects we have in our repository.
The projects are broadly divided into 3 list: first, second and heavy.
As for now, vast majority of the modules require JDK8 to build and run correctly.
Next, they are segregated further on the basis of tests that we want to execute.
The projects are broadly divided into 3 lists: first, second and heavy.
Therefore, we have a total of 6 profiles:

Additionally, there are 2 profiles dedicated for JDK9 and above builds.
