4 years ago Hello, @phlummox !
I don't think I can give you a satisfactory answer for this, but at least I'd like to let you know where things stand.
I have focused (for a while... >_>) on finishing version 0.6 of the language. Version 0.6 works with the latest Leiningen, and on Java 13. Which is to say, I addressed the issue that you mentioned... but only for v0.6.
That is because I haven't worked on keeping v0.5 (which is the version used in the book) up to date, since I feel there's not much point in doing so since v0.6 is what I need to be focusing on.
I realize that's not a good answer for someone who just wants to try out Lux and only has access to v0.5 (and the only available book only covers v0.5).
For what is worth, I expect to have a release-ready v0.6 JVM compiler by the end of June or early July. I could also update parts of the book on demand for people who want to play around with it.
But right now I don't want to spend time updating v0.5 or back-porting v0.6 changes into it, as I feel it would be a distraction.
I apologize for the current state of affairs. It's mostly a consequence of how long it has taken me to develop v0.6, but hopefully it will all be worth it soon.

It seems it's a common stumbling block for people to be unable to build even a "Hello world" program in Lux due to their using versions of Leiningen and the JDK that Lux doesn't work with - e.g. #41.
Rather than just closing those issues, could I suggest that it might, perhaps, be useful to add to both the README and to the Lux book (assuming the URL I have for it is up to date - perhaps this has already been added) a new section called "Prerequisites" which details the versions of JDK and Leiningen which Lux is known to work with?
