在Leiningen项目的Google Maven回购中找不到Firebase jar

• 问答

我有一个使用Leiningen的Clojure项目，需要访问Firebase Admin SDK。因此，我尝试使用Google Maven中的Java版本。当我运行lein repl时最终发生的事情是开始下载该特定jar的所有要求，但随后崩溃并出现以下错误：

Could not find artifact com.google.firebase:firebase-database:jar:19.0.2 in central (https://repo1.maven.org/maven2/)
Could not find artifact com.google.firebase:firebase-database:jar:19.0.2 in clojars (https://repo.clojars.org/)
Could not find artifact com.google.firebase:firebase-database:jar:19.0.2 in google (https://maven.google.com/)
This could be due to a typo in :dependencies,file system permissions,or network issues.
If you are behind a proxy,try setting the 'http_proxy' environment variable.

我的project.clj如下：

(defproject xxxxx "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"}
  :dependencies [[org.clojure/clojure "1.9.0"]
                 [http-kit "2.3.0"]
                 [datascript "0.18.7"]
                 [com.google.firebase/firebase-database "19.0.2"]]
  :main ^:skip-aot xxxxx.xx
  :target-path "target/%s"
  :profiles {:uberjar {:aot :all}}
  :repositories [["google" "https://maven.google.com/"]])

实际的项目名称已经被x代替了。

对这个问题可能有什么想法？顺便说一下，我在Ubuntu 18.04上。

com.google.firebase：firebase-database：jar：19.0.2不是Firebase Admin SDK的依赖项。那就是Firebase Realtime Database Android客户端SDK。

如documentation中所示，Java的Firebase Admin SDK的最新版本是com.google.firebase：firebase-admin：6.11.0。
