ClassCastException thrown by boot-figreload

[DonyorM]

Currently my code is throwing the following error when running the command boot -vv figwheel:

This is the figwheel task:

(deftask figwheel
  "Runs figwheel and enables reloading."
  []
  (dev)
  (require '[powerlaces.boot-figreload :refer [reload]]
           '[pandeiro.boot-http :refer [serve]])
  (let [reload (resolve 'powerlaces.boot-figreload/reload)
        serve (resolve 'pandeiro.boot-http/serve)]
    (comp
     (watch)
     (reload :client-opts {:debug true})
     (cljs-repl)
     (cljs)
     )))

This occurs after boot outputs "Compiling ClojureScript". I do not see this error if I run boot cljs or boot cljs-repl without the figwheel setup.

You can see my full build.boot file here.

My main.cljs.edn file is:

{:require [test.core]
 :compiler-options {:main "test.app",
                    :asset-path "/js/out",
                    :output-to "target/cljsbuild/public/js/app.js",
                    :output-dir "target/cljsbuild/public/js/out",
                    :source-map true,
                    :optimizations :none,
                    :pretty-print true}}

Thank you I will fix this.

[arichiardi]

Actually it seems like this is triggered by boot-cljs, can you confirm @DonyorM?

[DonyorM]

@arichiardi Reloading (either by boot-figreload or ordinary boot-reload) is certainly involved. Running boot cljs by itself causes no issues.

[arichiardi]

I copied from boot-cljs big chunks of code that is why :stuck_out_tongue:

[arichiardi]

Fixed in https://github.com/boot-clj/boot-cljs/pull/165

[DonyorM]

Works beautifully with the addition. Thanks for the fix.
