Relation Between Component Versions and JIRA's Own Versions
The plugin uses JIRA's own versions, so no magical version field is created. The add-on allows mapping of more than one component to single version. For example you can map both component Android and component iOS to version 1.0. If you check JIRA's own Version Tab, there will be one version 1.0. But you can also create more than one version 1.0 with suffixes like 1.0-android and 1.0-iOS. In that case you can map component Android to version 1.0-android and component iOS to version 1.0-iOS. This schema makes relationship between a version and a component more explicit and even if you uninstall the add-on in the future, you can still see which versions are used for which components.
