IOFactory error when used in Uberjar

[jkutner]

When postal is used in a uberjar, it fails trying to read the pom.properties file with this error:

java.lang.IllegalArgumentException: No implementation of method: :make-input-stream of protocol: #'clojure.java.io/IOFactory found for class: nil

WORKAROUND:
Add -Dpostal.version=1.11.3 to java process

I also experienced this issue.

@drewr any chance we can get a patch release if a PR is provided?

[drewr]

Yes! PR welcome. The packaging is very old and needs to be redone. I use a version.txt file in resources/ in other projects which works with uberjars too. Will do it if you don't get to something like that first. Thanks!

Experienced the same issue.

Dirty hack: (System/setProperty "postal.version" "1.11.3") at runtime.
