依存関係の定義について

  • 依存関係の定義は project.clj の :dependencies ベクターで行う。
  • :dependencies には [<グループID/アーティファクトID> "<バージョン>"] と書く。（Mavenと同じ感覚。）
  • グループIDとアーティファクトIDが同じであれば、２つ書く必要がなく、グループIDを省略していい。
  • 例えば clj-http の場合はグループIDとアーティファクトIDが同じなので [clj-http "3.12.3"] と書ける。
  • leinは :dependencies を見て、依存先をダウンロードする。
  • 明示的にダウンロードしたい場合は lein deps コマンドを使う。

やってみる

  • clj-http を依存先に追加してみる。
  :dependencies [[org.clojure/clojure "1.11.1"]
                 [clj-http "3.12.3"]]
  • lein deps で clj-http をダウンロードする。

外部リポジトリについて

  • 検索同様、leinはMavenCentral、Clojarから依存ライブラリを取得する。
  • MavenCentralはご存知の通り、Javaの主なライブラリが置いてある。
  • Clojarは主にClojurコミュニティが集中してライブラリを配置している。
  • その他のリポジトリを参照する場合は、project.cljの :repositories で設定する。
  • sample.project.clj が参考になる。
