Steve Rowe commented on LUCENE-8616:
------------------------------------

Related: Elasticsearch had wildcard exclusions for a while and then put back 
their explicit exclusions, because 3rd-party tools like Ant didn't understand 
wildcard exclusions, see https://github.com/elastic/elasticsearch/pull/24879

Ivy 2.5.0-rc1, released 8 months ago, includes wildcard exclusions support 
(IVY-1531).  There has been no discussion on the Ant dev mailing list about a 
final 2.5.0 release, but I found an ivy-user@ post from an Ant dev ( 
https://lists.apache.org/thread.html/e911b9ea3b8c415de2927f3762ba0866465d95ee75aed6c6b336276a@%3Civy-user.ant.apache.org%3E
 ) that says:

2.5.0-rc1 has a major issue that's being tracked as part of IVY-1580. I have 
been working on it but haven't had enough time to get a right solution for it. 
A fix for that would be necessary to release rc2 of Final of 2.5.0. I don't 
have an exact time frame for the release, but I'll send a note on the dev list 
once I have something.

Unfortunately there has been no activity on IVY-1580 since then, and 
Elasticsearch's latest POMs still have explicit exclusions.

Should we delay implementing wildcard exclusions until after Ivy 2.5.0 final 
has been released?

> Right now the Maven build disables transitive dependency resolution for all 
> dependencies by listing each dependency's dependencies in a nested 
> {{<exclusions>}} section in the grandparent POM's {{<dependencyManagement>}} 
> section. 
> As of Maven 3.2.1, it's possible to use a wildcard syntax in nested 
> {{<exclusions>}} sections to exclude all transitive deps: MNG-2315. This 
> would make the grandparent POM much smaller and make the intent much clearer.
> We would have to increase our minimum supported Maven (currently 2.2.1), but 
> that seems reasonable, given that Maven 2.x has been EOL'd: 
> https://maven.apache.org/maven-2.x-eol.html
