java - 在 Leiningen 项目的 Google Maven 存储库中找不到 Firebase jar

Question

我有一个使用 Leiningen 的 Clojure 项目，需要访问 Firebase Admin SDK。所以我尝试使用 Google Maven 的 Java 版本。当我运行 lein repl 时，最终发生的情况是它开始下载该特定 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/"]])

实际项目名称当然已替换为 x。

你知道这个问题可能是什么吗？顺便说一下，我使用的是 Ubuntu 18.04。

Answer 1

com.google.firebase:firebase-database:jar:19.0.2 不是 Firebase Admin SDK 的依赖项。这就是 Firebase 实时数据库 Android 客户端 SDK。

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