每次都去网上查看每个依赖的包是否有更新是一件很麻烦的琐事。尤其是有很多依赖的时候。对于clojure，可以使用lein-ancient进行管理。

检查

在项目中加入该插件后，只要执行lein ancient就可以对依赖项进行检查。非常方便。

$ lein ancient[org.clojure/clojurescript "0.0-2371"] is available but we use "0.0-2356"[compojure "1.2.1"] is available but we use "1.2.0"[com.cognitect/transit-cljs "0.8.192"] is available but we use "0.8.188"

此外lein-ancient也提供了一些查看过滤选项：:allow-snapshots,:allow-qualified, :allow-all, :plugins, :all, :recursive

如果要对~/.lein/profiles.clj进行更新，则执行lein ancient profiles [<options>]

升级

仅仅只检查是不够滴，还可以通过该插件对依赖项进行升级

$lein ancient upgrade :interactive[org.clojure/clojurescript "0.0-2371"] is available but we use "0.0-2356"Do you want to upgrade? [yes/no] yes[compojure "1.2.1"] is available but we use "1.2.0"Do you want to upgrade? [yes/no] yes[com.cognitect/transit-cljs "0.8.192"] is available but we use "0.8.188"Do you want to upgrade? [yes/no] yes3 artifacts were upgraded.

另外，lein-ancient也支持回归测试。如果升级完的测试失败，会自动回滚到升级前的版本。也可以用它来查看指定组件的版本信息：
