     [ https://jira.codehaus.org/browse/MRELEASE-734?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Scholte updated MRELEASE-734:
------------------------------------

    Fix Version/s: 2.4
         Assignee: Robert Scholte

For MRELEASE-511 this part of the code will be refactored, so this issue should be fixed as well.

> In my case I would like to pass {{releaseVersion}} and {{developmentVersion}} taken from user input, e.g. from [Hudson Release Plugin|http://wiki.hudson-ci.org/display/HUDSON/Release+Plugin]:
> {code}
> release:prepare release:perform -DreleaseVersion=${RELEASE_VERSION} -DdevelopmentVersion=${DEVELOPMENT_VERSION}
> {code}
> however if user leaves input fields empty it would be nice if maven-release-plugin would treat empty values as non-defined and fallback to default behaviour: inherit the next version from pom. Currently it breaks down with message 'Unable to parse the version string ""'.
