Hi. Related to the lein check, there is another related error. Running lein uberjar compiles the files in non-deterministic order: locally (osx) it works, but with docker (linux x86-64) it fails as the compilation order is different and the satisfy? fails as the protocols have been changed during the compilation process. Here’s a sample (a Luminus template project with few addons) on how to get the error: • https://github.com/ikitommi/uberjar-problem here’s a minimalistic example showing that the compilation order matters: • https://github.com/ikitommi/fun

Sounds similar to a ticket that’s out there about nondeterministic protocol compilation

Oh never mind, that was with proxies not protocols https://dev.clojure.org/jira/browse/CLJ-1973

But compilation order definitely matters

This looks pretty similar to https://dev.clojure.org/jira/browse/CLJ-2303

CLJ-2303 looks related, linked the issue into there. Should this be fixed in Clojure compiler itself or in the build tools (e.g. leiningen)? Leiningen could reorder the compilation files with tools like tools.namespace?

hey guys, can you help me with this error?
