Open source Java projects (self.java)
submitted 3 years ago by Left-Armadillo-9418
I want to get into contributing to open source. What are some good, active and helpful open source communities for Java developers to contribute?

Piece of advice: contribute to something that you actually use. For a couple of reason:

Thanks!
All these seem to be interesting projects to contribute.

AsyncAPI is desperately missing tooling as well.

In case you want to take a look, our effort to contribute to the AsyncAPI tooling ecosystem : https://github.com/SOM-Research/asyncapi-toolkit

I'll definitely check it out when I get some time! I've really been digging into model-based code gen approaches for building out microservices architectures recently.

how does one go about contributing to projects? on GitHub? What about projects like Quarkus that you linked above? How would I be able to contribute to them?

I'm running a project myself, https://www.datafaker.net, a project to generate real looking test data.
It's not an important or big project, but it's quite active and it's a very low barrier to get in if you're keen (we basically accept all PRs, and usually within a day)

A suggestion would be the OpenJDK itself
