How to get the project version description in Jira via the Soap api

Does anybody know how to get the version description field for a Jira project? Using the ProjectService.getVersions method we can get an Array of RemoteVersion objects but these RemoteVersion objects do not contain the description field.

Documentation for ProjectService.getVersions():开发者_运维技巧

getVersions
RemoteVersion[] getVersions(com.atlassian.crowd.embedded.api.User user,
                            java.lang.String projectKey)
                            throws RemoteException
Throws:
RemoteException

Will I have to expose my own web service via a Jira plugin to get this?

According to Atlassian support this is not possible (yet).
