pack.alpha: NullPointerException with specific depedency

Hello!

The following exception is thrown when I add metasoarous/oz in deps.edn and trying to build an uberjar:

Exception in thread "main" java.lang.NullPointerException

Bellow is a minimal deps.edn that reproduces the issue:

{:deps {metasoarous/oz {:mvn/version "1.6.0-alpha5"}}
 :aliases {:pack {:extra-deps {pack/pack.alpha {:git/url "https://github.com/juxt/pack.alpha.git"
                                                :sha "81b9e47d992b17aa3e3af1a47aed1f0287ebe9b8"}}
                  :main-opts  ["-m"
                               "mach.pack.alpha.capsule"
                               "app.jar"
                               "-e" "target"
                               "--application-id" "app"
                               "--application-version" "\"1.0.0\""]}}}

Great 😃 I’ve mentioned this upstream to t.d.a as well. I don’t think there’s anything they can do.

As a note, I’m not certain oz will work with that exclusion, you may wish to add that version of the oz dependency to the pack alias. That should mean it’s only excluded when building with pack, and is still included in your application.

here’s what I mean by example:

{:deps {metasoarous/oz {:mvn/version "1.6.0-alpha5"}}
 :aliases {:pack {:extra-deps {pack/pack.alpha {…}
                               metasoarous/oz {:mvn/version "1.6.0-alpha5"
                                               :exclusions [org.apache.maven/maven-aether-provider]}}}}}

Got it. Use this for oz instead:

metasoarous/oz {:mvn/version "1.6.0-alpha5"
                  :exclusions [org.apache.maven/maven-aether-provider]}
