maven, browse central repository via command line client - maven-2

Question

Is it possible via regular mvn command line client to browse the central repository, and possibly perform a specific search?
e.g: i want to get a list of all the artifacts that have "log4j" in their Artifact ID.

I whipped up a little Groovy script that does this:
import groovyx.net.http.URIBuilder
import groovy.json.JsonSlurper
class Fun {
public static void main(String[] args) {
def uri = new URIBuilder("http://search.maven.org/solrsearch/select")
uri.addQueryParam 'rows', 20
uri.addQueryParam 'wt', 'json'
uri.addQueryParam 'q', args[0]
def text = uri.toURL().getText()
def json = new JsonSlurper()
def result = json.parseText( text )
result.response.docs.each { doc ->
println "$doc.id:$doc.latestVersion"
}
}
}
And here's a Ruby script that does the same thing (using the httparty gem):
require 'httparty'
query = ARGV[0]
class MavenCentral
include HTTParty
base_uri 'search.maven.org'
def initialize(query, rows=20)
#options = { query: {rows: rows, wt: 'json', q: query} }
end
def artifacts
self.class.get('/solrsearch/select', #options)
end
end
maven_central = MavenCentral.new(query)
maven_central.artifacts['response']['docs'].each do |doc|
puts "#{doc['id']}:#{doc['latestVersion']}"
end

There is an SBT plugin for this: sbt-search-maven-plugin
$ sbt "searchMaven log4j"
