Subject Re: continuous releasing: versions:set and/or release:update-version to release an aggregator project
Date Thu, 01 Aug 2013 18:01:00 GMT
This is exactly what I needed a couple of weeks ago. I came up with the
same procedure but discovered that the versions plugin doesn't support
unresolving ranges. Is this something that's in the works or it's just
something you wish  were there?

            release:update-version to release an aggregator project

How I want this to work is to have versions-maven-plugin have a way to undo
versions:resolve-ranges ( -
it would need to ensure that the lower bound of any unresolved range is the
resolved version... [see below]

We'd need to split preparationGoals in the release plugin... either into
preparationGoals + verificationGoals or into initiationGoals +
preparationGoals (I favour the latter as it preserves the semantics of
preparationGoals... but the first one maps more correctly with what each
set should be doing)

Then this would become super easy...

You develop with version ranges for your dependencies...

The release plugin would have
    initiationGoals = versions:resolve-ranges versions:commit
    preparationGoals = clean verify
    completionGoals = versions:unresolve-ranges versions:commit

So say your development pom has


and the latest version of foo is 1.2

When you kick off the release, the range gets resolved to

  <version>1.2<?versions range="[1.0,2.0)"?></version>

(My current thought is to use an XML PI to stash the old range)

Then we invoke Maven again (because Maven doesn't re-read the poms) and do
a "clean verify" to make sure that this all builds

Then we tag the release

Then we run completionGoals and versions:unresolve-ranges puts the version
range back, but upping the lower bound


Maven ups the pom version to next development snapshot and commits the pom

That will give you the ability to develop on ranges (which is nice and
flexible) but release on pinned versions (which is exactly what you should
be doing)

If we cannot deliver something like that, then I think we should just drop
ranges from the next major version of Maven.
