I followed the Getting Started guide and nothing worked well, except for the boot with nix installation.
The clj tools Linux instructions failed the same way the lein one failed: Error with some certs [1] I've been told that this problem could be solved if I install Oracle Java instead of using OpenJDK. I don't want to do that. I avoided the local build instructions because it was going to require maven. I don't want to use it for now. So, for now I'm working with the Clojure 1.8 jar. I must say, Clojure is a good language, but the tooling is awful, not userfriendly, not beginers friendly. Maven is a beast, is the only thing had keped me away of Java for years, and now I must live with it, Voluntarily (I'm learning Clojure not because the work, but because I like it too much). Probably I should try Clojurescript instead. Thank you.
