Description of problem:
xmvn-builddep outputs namespace instead of compat version.

Version-Release number of selected component (if applicable):
javapackages-tools-4.6.0-0.15.giteccdd3f.noarch

How reproducible:
always

Steps to Reproduce:
1. rebuild https://msimacek.fedorapeople.org/jspc-2.0-0.15.alpha.3.fc21.src.rpm
2. run xmvn-builddep on the build.log


Actual results:
there's this line in the output:
BuildRequires:  1.8.9-mvn(org.codehaus.groovy:groovy)

Expected results:
BuildRequires:  mvn(org.codehaus.groovy:groovy:1.8.9)

Additional info:
XMVn's output contains
<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy</artifactId>
    <version>1.8.9</version>
</dependency>
So it seems like javapackages bug.
