jenv VS nix.dev

https://github.com/jenv/jenv to switch among multiple Java versions

I would recommend https://www.jenv.be/

Look at the https://www.jenv.be/ configure section and add the Java location where Homebrew installed your java. If I remember correctly, it should be somewhere in /usr/local/Cellar/openjdk/**

On my case I prefer use jenv (which is available on aur)

You might like jenv

There are a handful of different ways to temporarily swap out Java versions. In this case, you could probably edit the start scripts to point directly to the path for the Java version you want to use (instead of just "java" which is most likely referring to the most recent). I was already using jEnv for other things, so I configured it so JRE 1.6 would be used in my Nullpomino directory, and the latest JRE would be used everywhere else.

I like jenv for that. You can have a java version set per-project, systemwide, shell session, etc.

I don’t know if this is the “correct” way, but if you are Unix based I would recommend jenv. This is a Java environment manager, similar to pyenv if you know it. Using this tool you can easily switch from one installed version to another. It makes managing Java versions a bliss.

Nix (https://nix.dev/) can provide all of this, although in a smarter way than just through dumping everything in the VCS. Some projects use it already to provide a reproducible development environment and if done right a clean build is just a `nix-build` away.

Author doesn’t mention it but I wonder if tried or considered Nix/NixOS’s reproducible developer environments and ruled them out for any reason. I couldn’t tell from the article if there’s something unique to his requirements that disqualifies them.

if you want something a more in-depth, zero to nix is a great resource for all things nix (they have a section dedicated to flakes here, but i would pay attention to the notice at the top about reading some other things first), along with nix.dev, and of course, the nixos wiki article on flakes

On nix.dev it say I would need to cross compile to make it work, is there some way in which i can build natively on my machine.

Hey

Cachix founder here. Here are a few links for getting started:

- https://nix.dev Nix tutorials

- https://devenv.sh Fast, Declarative, Reproducible, and Composable Developer Environments

Let me know if you have any questions. Domen

Nix pills and nix.dev are my favorites, alongside the official documentation.

https://nix.dev/ is the best in depth resource I know but it's a work in progress.

For folks looking to understand why this is so https://nix.dev and https://devenv.sh/
