Hi! I'm trying to convert the template project to boot but when I try to build a jar of the main class I get this error on runtime
Exception in thread "main" clojure.lang.ExceptionInfo: Error on key :duct.profile/base when building system {:reason :integrant.core/build-threw-exception, :system {}, :function #object[clojure.lang.MultiFn 0x5972d253 "clojure.lang.MultiFn@5972d253"], :key :duct.profile/base, :value {:duct.core/project-ns redblack-duct, :duct.router/ataraxy {:routes {[:get "/example"] [:redblack-duct.handler/example]}}, :redblack-duct.handler/example {}}}

I did comment out the db stuff from the config.edn temporarily like so
{:duct.profile/base
{:duct.core/project-ns redblack-duct
:duct.router/ataraxy
{:routes {[:get "/example"] [:redblack-duct.handler/example]}}
:redblack-duct.handler/example{}
;; {:db #ig/ref :duct.database/sql}
}
:duct.profile/dev #duct/include "dev"
:duct.profile/local #duct/include "local"
:duct.profile/prod {}
:duct.module/logging {}
:duct.module.web/api
{}
:duct.module/cljs
{:main redblack-duct.client}
;; :duct.module/sql
;; {}
:duct.module.web/site
{}}
What does your redblack_duct.main namespace look like? Are you requiring duct.core? If you are, what does your dependency tree look like?
The namespace looks like:
(ns redblack-duct.main
(:gen-class)
(:require [duct.core :as duct]))
(duct/load-hierarchy)
(defn -main [& args]
(let [keys (or (duct/parse-keys args) [:duct/daemon])
profiles [:duct.profile/prod]]
(-> (duct/resource "redblack_duct/config.edn")
(duct/read-config)
(duct/exec-config profiles keys))))
That seems fine - it loads in duct.core where :duct.profile/base is defined. So the other thing to check is your dependency tree to ensure you have the right version. In Leiningen that's lein deps :tree, but I don't know what it would be under Boot.
Are you building an uberjar? If so, have you correctly merged the duct_hierarchy.edn resources?
Hmm I'm not sure. It's in resources but I'm sure if it's being included. Do you know how I could check?
If you haven't explicitly written code to account for it, that's probably your issue. When you're combining resources into an uberjar, you need to be careful about resources that share the same path.
In the Leiningen plugin, I've added some middleware to merge the duct_hierarchy.edn resources when building the uberjar. You'll need to do something similar in Boot. I assume it has some equivalent mechanism for handling uberjar resource merges.
I think I figured out how to include the duct_hierarchy.edn file but now I'm getting a stranger runtime exception

With duct_hierarchy.edn you need to use the Boot equivalent to Leiningen's :uberjar-merge-with key. I'm not sure how you've managed to exclude clojure.lang.Var - that class should be in the Clojure dependency!
I just had a quick look at Boot. It has a :mergers option for uberjars, so you should be able to add: [ #"duct_hierarchy.clj$" into-merger] to your mergers in order to get it working correctly, assuming that you haven't discovered that already.
That gives me
