Re: Lots of problems resolving maven dependencies in Ant

Sorry, but this ant "corner" is out of my paths.

Your idea is worth trying:
--
[artifact:dependencies] from the specified remote repositories:

[artifact:dependencies]   maven-group (https://repo1.maven.org/maven2/),
[artifact:dependencies]   central (http://repo1.maven.org/maven2),
[artifact:dependencies]   main.repository (https://repo1.maven.org/maven2),
[artifact:dependencies]   jboss-public-repository-group (https://repository.jboss.org/nexus/content/groups/public-jboss/)
[artifact:dependencies]
[artifact:dependencies] Path to dependency:

It seems to have a hard-wired "central" pointing to <http://repo1.maven.org/maven2>. I've scoured my drive for a settings.xml file that might be setting this, but can't find one. Looking at the .poms in the artifact chain, I don't see them incorrectly specifying a repository, either (just in case they can).

Dropping that into ~/.ant/lib fixed the missing task, but now it needs org/eclipse/aether/resolution/ArtifactResolutionException. Why does Ant/Maven need stuff from Eclipse?
