boot fails with datomic-free

[ulsa]

If I have datomic-free (any version, it seems) as a dependency, I get this output when I run boot:

$ boot development
org.apache.commons.codec.binary.Base32

If I remove the datomic dependency, like so:

  :dependencies '[[tailrecursion/boot.task   "2.2.1"]
                  [tailrecursion/hoplon      "5.10.8"]
                  [org.clojure/clojurescript "0.0-2234"]
                  [tailrecursion/boot.ring   "0.2.1"]
                  #_[com.datomic/datomic-free "0.9.4815.12"]
                  [datascript "0.1.6"]
                  [org.clojure/algo.generic "0.1.2"]
                  [lein-light-nrepl "0.0.18"]
                  [org.clojure/tools.nrepl "0.2.3"]]

then it works fine:

$ boot development

nrepl running on 56592

Odd! I was not able to reproduce. The build.boot I tested with is below. Could you please post your full build.boot and platform?

#!/usr/bin/env boot

#tailrecursion.boot.core/version "2.5.0"

(set-env!
  :project      'someapp
  :version      "0.1.0-SNAPSHOT"
  :dependencies '[[tailrecursion/boot.task   "2.2.1"]
                  [tailrecursion/hoplon      "5.10.8"]
                  [org.clojure/clojurescript "0.0-2202"]
                  [tailrecursion/boot.ring   "0.2.1"]
                  [com.datomic/datomic-free  "0.9.4815.12"]
                  [datascript                "0.1.6"]
                  [org.clojure/algo.generic  "0.1.2"]
                  [lein-light-nrepl          "0.0.18"]

(require '[tailrecursion.hoplon.boot :refer :all])

(deftask development

Created new hoplon-castra project, then manually added changes according to Daniel Neal's video.

I added datomic as a dependency.

I got the same error, org.apache.commons.codec.binary.Base32, when using [tailrecursion/hoplon "5.10.11"] but it runs ok with [tailrecursion/hoplon "5.10.7"]

[alandipert]

I transplanted the :dependencies into a project.clj and ran lein deps :tree to see what was going on.

I discovered that datomic-free was bringing in a version of commons-codec (the library org.apache.commons.codec.binary.Base32 is in) that conflicts with what castra depends on via crypto-random:

([com.datomic/datomic-free "0.9.4815.12"] -> [com.amazonaws/aws-java-sdk "1.6.6" :exclusions [javax.mail/mail org.apache.httpcomponents/httpclient commons-logging]] -> [commons-codec "1.3"])
( overrides)
([tailrecursion/hoplon "5.10.8"] -> [tailrecursion/castra "2.1.0"] -> [crypto-random "1.2.0"] -> [commons-codec "1.6"])

We have tentative plans to move boot to a system using multiple JVMs that could help circumvent these kind of Maven/classloader nightmares. In the meantime though, as with lein, we are subject to them.

One fix is to bring in Datomic like this:

[com.datomic/datomic-free "0.9.4815.12" :exclusions [commons-codec]]

Work-around OK. Thanks.
