boot show -u fails when SNAPSHOT dependencies present

[micha]

Thanks @whodidthis for reporting the issue. This repo whodidthis/boot-show-u demonstrates the problem.

Description of Problem

Lein project [example.checkout "0.1.0-SNAPSHOT"] installed locally. Boot project has dependency on the Lein project.

build.boot

#!/usr/bin/env boot

(set-env!
  :src-paths #{"src"}
  :dependencies '[[adzerk/boot-cljs "0.0-2371-25"]
                  [example.checkout "0.1.0-SNAPSHOT"]])

(require '[adzerk.boot-cljs :refer :all])

(task-options!
  pom [:project 'boot-show-u
       :version "0.1.0-SNAPSHOT"])

To reproduce the error:

$ boot -V

#https://github.com/boot-clj/boot
#Thu Nov 20 10:21:50 EST 2014
BOOT_CLOJURE_VERSION=1.6.0
BOOT_VERSION=2.0.0-pre24

$ boot show -u

Workaround

This issue appears to be related to boot -u and snapshot dependencies that are installed locally. The issue can be worked around by adding the -s (--snapshots) option:

$ boot show -us
