Re: Maven Release Plugin - release:branch: branch versions not set as expected

Fri, 29 Aug 2014 09:51:51 -0700 

Hi,
IMO branches are mutable, so it makes sense that this will always result in a -SNAPSHOT 
Only tags are considered immutable, so that will get a NON Snapshot.
IIRC only the versions of one of the poms will be updated, either the one staying on the trunk or the one moved to the branch. 

thanks,
Robert

(please see bottom of email for environment/version information)


I am trying to use the "release:branch" goal to create a branch, setting  
the version in the POMs in both the new branch and the working copies.   
No matter what properties I define on the command line, the release  
plugin is overriding the branch version information to what it thinks  
(incorrectly in my opinion) it should be.  It looks like the release  
version is being set either by calculation from current project version,  
or supplied development version.


I.e.  when calling Maven with the following (snippet)

-DreleaseVersion=1.0.0
-DdevelopmentVersion=1.0.1-SNAPSHOT
-DupdateVersionsToSnapshot=false
-DdryRun=true


The version in all the pom.xml.next files is as expected  
(1.0.1-SNAPSHOT), but the version in all the pom.xml.branch files is not  
as expected (1.0.1-SNAPSHOT when I would expect 1.0.0).



Am I missing something that would explain why the above is correct?  Or  
am I missing something obvious in how to configure the plugin to work as  
expected?


(I've included a very simple repro in the grey breakout box below )

Thanks
Mark

I've tried specifying all modules independently (with the  
-Dproject.rel.org.gibbo:child-one etc pattern), but the release versions  
in the branch are still overridden incorrectly.
