A couple of months ago, I wanted to get my first open-source experience. What was I supposed to do? I googled “best Java open source projects” and was terrified; every website recommended Spring, Gradle, Mockito, Guava, Jenkins and etc. There’s a website called GoodFirstIssue, I was really happy when I found it, but it was also a disappointment. The logical question arises why? 

I will not believe that someone gets his open-source experience with projects like this. Their enormous, and it will get months, in the best case, to understand how they work. So I started researching myself; I’ve looked at several hundred projects to choose the bests for me. Here I will share my experience and projects that I’d like to start my open-source.
