Jason van Zyl commented on MARTIFACT-35: ---------------------------------------- Mercury allows for any implementation, but Mercury is not Maven. Mercury was designed to support any arbitrary system. That does not mean we want to allow these arbitrary capabilities in Maven. In fact we don't. Allowing arbitrary version schemes requires a lot of work in Maven to support. Everything would need to support it and your clients need to really understand the real cost of wanting something different. I ardently believe that we don't need N version systems. One decent one like OSGi is a good start and we can help improve that one. > Allow the ability to "plugin" or "inject" different versioning implementations > ------------------------------------------------------------------------------ > > Key: MARTIFACT-35 > URL: http://jira.codehaus.org/browse/MARTIFACT-35 > Project: Maven Artifact > Issue Type: Improvement > Affects Versions: 3.0 > Reporter: Jason Chaffee > > Currently, maven's versioning for snapshot builds is > ${timestamp}-${build.number}. However, it is often the case that companies > have their own versioning requirements or conventions and there are different > models for versioning such as OSGI, etc. For example, eclipse plugin > versioning proposal has the following: > the major segment indicates breakage in the API > the minor segment indicates "externally visible" changes > the service segment indicates bug fixes and the change of development stream > the qualifier segment indicates a particular build > This may result their snapshot builds take the the form of 1.2.1.v20050506 or > 1.2.1.34 depending on they wanted to represent the qualifier segment. They > could use the timestamp in the form "v20050506" or they could use a build > number "34". > Also, many times companies would like to utilize the build number in the > final release version. For example, 1.2.1-SNAPSHOT is on build 34 when a > release is done. Instead of making the final artifact 1.2.1, they may wish > to make the final artifact 1.2.1.34 or 1.2.1-34. > I think it would be ok for maven to only actually implement their default > strategy, but I think allowing a different implementation to be injected > based on the user's needs would be extremely valuable. > Another option is change the way <version> works in the pom. Instead of > entering a string, perhaps it could have child elements such as the following: > <version> > <major>1</major> > <minor>2</minor> > <service>1</service> > <qualifer>${project.build.number}</qualifer> > <separator>.</separator> > </version> > Note: qualifer may be the same notion as classifier. However, it would be > nice to be able to specify to use a "." or a "-" or a "_" separator based on > whatever format your company abides by. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
