Malformed Maven POM Crashes antq

[harrigan]

I am working on a project with a dependency on https://github.com/dialex/JColor. Currently their pom.xml has a malformed SCM section (reported here dialex/JColor#75). This causes antq to crash with an NPE:

[##################################################] 48/48
Execution error (NullPointerException) at antq.util.url/ensure-git-https-url (url.clj:18).
Cannot invoke "Object.toString()" because "s" is null
