Ugh. I for one am sick of the discussions of whether to use maven or ivy, etc. in a Java project. Just as old is the conversation about whether the project should be an Apache project. The ant (later: ant+ivy) vs. maven thing and whether a (major) project should go into Apache has been ongoing since the early 2000s in one project or another.
It is interesting in relation to Voldemort, but egads... this is one of the reasons I'm glad to sneak away into Ruby, etc. a good bit.
