[jira] Commented: (MNG-3092) Version ranges with non-snapshot bounds can contain snapshot versions

["John Casey (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNG-3092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=140552#action_140552 ] 

John Casey commented on MNG-3092:
---------------------------------

I'd tend to favor the approach suggested by kenney on the mailing-list thread for this issue. Something like:

{noformat}
[1.1-1.2]{snapshots=false}
{noformat}

would approximate the sort of advice given to regular expressions in other languages (and maybe in java, can't remember), so there is some precedent. IMO, we can't find a "pure" way to switch this behavior on/off using straight range syntax as we've used it before.

Also, it's legitimate to me to exclude snapshots, since by definition snapshots are part of a development effort...as such, they could contain major regressions and other nasty bugs from version to version. So having a range like the above, I'd almost say the default should *exclude* snapshots, and use something like '\{snapshots=true}' to *enable* them...

I'm happy to put this code in place, but it may have to wait for 2.0.11 so we can have some soak time, to make sure it doesn't hose anything else.

> Contrary to the 2.0 design docs:
> "Resolution of dependency ranges should not resolve to a snapshot (development version) unless it is included as an explicit boundary."

> The following is equates to true:
> VersionRange.createFromVersionSpec( "[1.0,1.1]" ).containsVersion( new DefaultArtifactVersion( "1.1-SNAPSHOT" ) )
> The attached patch only allows snapshot versions to be contained in a range if they are equal to one of the boundaries.  Note that this is a strict equality, so [1.0,1.2-SNAPSHOT] will not contain 1.1-SNAPSHOT.
