[Lisp-cn] [clj] 如何用 doc 宏来探索 Java 文档?

[Zoom.Quiet]

clojure 应该也算 Lisp 方言吧?
可以视为工业规格的 scheme ?

所以开始刷 clj.
立即撞到了一个常识性操作的问题:

环境:
༄ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

༄ clj
Clojure 1.8.0

测试文件头部有声明:
(ns clj101.ns
(:require
[clojure.repl :as repl]
[clojure.string :as str]
[clojure.set :as set]
)
(:import
java.util.Date
java.util.Calendar)
)

....
;; 对应出问题的语句就是
(repl/doc java.util.Date) ;类似的尝试过
(repl/doc Date)
(repl/doc Date.getTime)
(repl/doc getTime)

都抛出类似错误:

Exception in thread "main" java.lang.RuntimeException: Unable to
resolve var: java.util.Date in this context,
compiling:(/opt/data/Sites/DU.xmq/br/clj_ZQ/_101/Learn_clojure_in_Y_minutes_cn.clj:285:1)
at clojure.lang.Compiler.analyzeSeq(Compiler.java:6875)
...

... 28 more


所以, doc 宏无法一致性的探索 Java 世界的模块/库/函式 的 docstring?
那大家开发 clj 时, 引用 Java 积累的模块, 还得另外安装 Java 文档仓库来搜索?
