Tamas Cservenak updated MRESOLVER-345:
--------------------------------------
Summary: Conflict resolution in verbose mode is sensitive to version
ordering (was: Conflict resolution is sensitive to version ordering)
> Conflict resolution in verbose mode is sensitive to version ordering
> --------------------------------------------------------------------
>
> Key: MRESOLVER-345
> URL: https://issues.apache.org/jira/browse/MRESOLVER-345
> Project: Maven Resolver
> Issue Type: Bug
> Reporter: Tamas Cservenak
> Priority: Major
>
> It all started with MENFORCER-426. In short, if we have layout of
> dependencies like this below (ranges are key here), *conflict resolution in
> verbose mode* will misbehave, is sensitive on version ordering in the "dirty
> tree" (collected graph, output of DependencyCollector).
> {noformat}
> A -> B -> C[1..2]
> \--> C[1..2] {noformat}
> (explained: A depends on B and C[1..2] range, and B depends on C[1..2] as
> well)
> As when "dirty tree" is being collected by DependencyCollector (and we have
> two, old DF and new BF), the ranges are turned into series of discovered (by
> VersionRangeResolver) versions, so the input above while collecting A from
> above would yield some tree like this (in this example {{some-group:c:jar}}
> has versions 1.0 and 2.0 ):
> {noformat}
> some-group:a:jar:1.0 [compile]
> +- some-group:b:jar:1.0 [compile]
> | +- some-group:c:jar:1.0 [compile]
> | \- some-group:c:jar:2.0 [compile]
> +- some-group:c:jar:1.0 [compile]
> \- some-group:c:jar:2.0 [compile] {noformat}
> This "dirty tree" is then transformed using {{ConflictResolver}} into final
> graph. Conflict resolver in "normal" mode works OK and produces stable
> outputs, that is not sensitive to ordering, this is OK.
> But, conflict resolver supports so called "verbose" mode as well, mostly used
> to perform some "analysis" on graph (like for example "dependency
> convergence" is). Conflict resolver in "verbose" mode {*}is version ordering
> sensitive{*}.
> Conflict resolver "verbose"
