I'm having trouble running boot dev on a template project. I get a ClassNotFoundException: javax.xml.bind.DatatypeConverter. I'm not sure who ordered that, so to speak.

https://pastebin.com/BqVnZxcP there's the full error.

hm. the template is ancient.

@braden.shepherdson i've run into that error a few times when using JDK 9+. https://www.deps.co/blog/how-to-upgrade-clojure-projects-to-use-java-11/#deprecations has an explanation

I'm running under JDK 11, so that seems likely to be the trouble. I'll try adding that dependency.

I also needed to update the CLJS dep from 290-something to 950-something (it needed cljs.spec.alpha at least), but now it's working.

every reload is duplicating my UI. that's getting more and more of a pain as it gets more complex. is there a standard way to make it replace instead of adding another copy when I reload?
