title: Why does leiningen download 1GB (almost) of jar indexes and how to stop that?
body: <p>Leiningen downloaded nearly 1GB of jar index information from repo1.maven.org and clojars.org. Why does it need to download that huge amount of information? And is there any way to prevent that?</p>
  
  <p>The directory in question is: <code>~/.lein/indeces</code></p>
  
  <p>It contains the following folders:</p>
  
  <pre><code>https___clojars.org_repo_
  https___repo1.maven.org_maven2_
  </code></pre>
  
  <p>The maven.org folder contains 849MB!</p>
  
  <p>Here is my project definition:</p>
  
  <pre><code>(defproject test-project "0.1.0-SNAPSHOT"
    :description "FIXME: write description"
    :url "http://example.com/FIXME"
    :license {:name "Eclipse Public License"
              :url "http://www.eclipse.org/legal/epl-v10.html"}
    :main test-project.core
    :dependencies [[org.clojure/clojure "1.6.0"]
                   [camel-snake-kebab "0.3.1" :exclusions [org.clojure/clojure]]])
  </code></pre>
  
  <p>Thanks</p>
