Currently it is possible to auto-suggest the version in jira. Therefore the version of the pom is used with '-SNAPSHOT' stripped.
If you have a product in jira with several components it is a often used pattern to prefix the version (e.g. component1-2.0, component2-1.0 etc.)
Currently these versions are not auto-recognized.
It would be better if it would be possible to optionally define a prefix (in this case 'component1-').
This would allow to use this feature also in prefixed-version-numbers
