Ivy 2.5.2 fixes a bug[1] when dealing with dependencies that have
multiple Maven artifacts with different Maven classifiers. Prior to
2.5.2 Ivy would think they'd all be the same and just pick one.
io.netty#netty-transport-native-kqueue has several artifacts, at least
this is what the repo looks like. I completely fail to understand the
POM :-)
Your pattern probably needs a [classifier] to make sure two artifacts
that differ by Maven classifier also target different file names.
Something like
pattern="${local-maven2-dir}/[organisation]/[module]/[revision]/[module]-[revision](-[classifier]).[ext]"
