`pom` dependencies lost when using `jar`

Say I have a task like:

``` clojure
(comp
(pom :project 'com.example/foo
:version "1.0"
;; ...
:dependencies '[[com.example/bar "0.1"]])
(jar)
(target))
```

The `pom.xml` created by `pom` includes all the right values, including ``. This is confirmed by looking at `target/META-INF/maven/com.example/foo/pom.xml`. However, the `pom.xml` included in the JAR has all the right values _except_ ``, which lists the default (the dependencies in the Boot environment).

The `jar` task is clearly picking up on the pom as the resulting file in `foo-1.0.jar`; without a valid POM it would simply be `project.jar`. Why are the custom dependencies lost?

Thanks for the amazing build tool!
