Description

« Hide

currently, the collector only:

selects nearest "suggested" version in a valid range
latest version from the valid ranges if none suggested
fails if ranges are over-constrained

This needs to be configurable:

select newest, even if there is a nearer suggestion
select oldest, even if there is a nearer suggestion
fail if all suggestions don't equate or a range results instead of a single version
ignore over constrained ranges and fallback to some other algorithm
select snapshots even if they weren't explicitly specified

Attached an initial stab at this - patch is against 2.0.x. Will send an email to dev to discuss it further without clogging up JIRA.

This issue should be targeted for 2.0.x since the new dependency graph API will make this patch obsolete in 2.1.

Branch update:

2.0.x:

https://svn.apache.org/repos/asf/maven/components/branches/MNG-612-2.0.x/

2.1.x:

Note that 2.1.x needs FIXME fixed in DefaultExtensionManager.addExtension before it can be functional.

The maven-artifact changes from this patch have been committed to maven-artifact 3.x. Only Maven 2.1 is using this version, see MNG-3205 for switching Maven 2.0.x over. The rest of the patch outside of maven-artifact still needs to be applied to 2.0.x and 2.1.
