Arkadiusz Biczewski commented on MNG-8569: ------------------------------------------ I am strongly against removing version ranges from maven as this is really useful feature to have well defined continous builds. We use version range in developemnt phase to consume latest builds prepared by other team (which are numbered like 2.3.0.x, where x is the build number for given release, which is used instead of a snapshot for easier identification of used version), but when generating our artifact out of the project, we make use of versions:resolve-ranges -Dincludes=com.companyGroupId. That way we have best of two worlds - builds are more defined than with snaphots usage, doesn't require manual bumping of libraries, but in case when repeated build is neaded one can easily check the exact used components version. The main concern raised in the discussion is of course valid, as with artifacts available in public repositories one cannot be so sure about actors itentions, as with artifacts used internally and released to internal repositories/nexus instances. Maybe the solution would be to have some setting at *repository* entry level whether version ranges are allowed or not (the same like currently there is a flag whether snapshot / release versions are to be used from given repository or not). Or to have the resolution strategy at the *repository* entry level (like prefer lower / prefer higher). Personally (or rather professionally) I would even seen the extension to the supported version ranges syntax: MNG-8652 and planned to contribute that change to have better flexibility when using gradle and maven in different subcomponents. But as the issue got linked to this one, looks like the preferred solution would be to get away from maven at all :(. > Deprecate and remove version ranges > ----------------------------------- > > Key: MNG-8569 > URL: https://issues.apache.org/jira/browse/MNG-8569 > Project: Maven > Issue Type: Improvement > Reporter: Elliotte Rusty Harold > Priority: Major > Fix For: 4.x / Backlog > > > To protect Maven users, we should eliminate, or at the very least warn, when > version ranges are used in dependency elements.
