我创建了一个具有以下内容的 luminus 项目

lein new luminus chess +auth +swagger +cljs

我正在尝试使用 google datastore api，但遇到了这个问题

无法调用非公共类的公共方法：public（Google gcloud 库）

尝试从 clojure 调用 api 时。所以我试图将我对 api 的使用包装在我自己的 Java 代码中，然后我从我的 Clojure 代码中调用这些代码。

我的导入我的 java 代码的代码如下，它甚至还没有从 gcloud 导入中调用代码。

(ns chess.routes.home
  (:require [chess.layout :as layout]
            [compojure.core :refer [defroutes GET]]
            [ring.util.http-response :as response]
            [clojure.java.io :as io])
  (:import [gcloud GCloud]))

(defn home-page []

  (layout/render "home.html"))

(defroutes home-routes
  (GET "/" []
       (home-page))
  (GET "/docs" []
       (-> (response/ok (-> "docs/docs.md" io/resource slurp))
       (response/header "Content-Type" "text/plain; charset=utf-8"))))

而我的java代码只是

package gcloud;

public class GCloud {
    public static void put() {
        System.out.println("sdfsd");

    }

}

然而，当我执行 lein javac 时，它会失败如下。如果我从 clojure 代码中删除 gcloud 导入，那么 lein javac 会成功地在目标目录中为我的 java 代码输出一个类文件。但是为什么 lein javac 甚至完全看 clojure 代码而不处理纯 java 呢？

$ lein javac

因为 :dev 配置文件默认启用。

您可以在没有 :dev 配置文件的情况下进行编译：

lein with-profile -dev javac
