如何解决ElasticSearch库依赖错误

Question

我正在尝试使用 Scala 设置 ElasicSearch 客户端。我是 Scala 新手，所以我正在关注一些建议

elastic4s-client-esjava

的在线教程。我已经在我的

build.sbt

中完成了该设置，其余的库依赖项如下：

name := "ElasticSearchService"

version := "0.1"

scalaVersion := "3.5.2"

libraryDependencies ++= Seq(
  "org.postgresql" % "postgresql" % "42.3.1",
  "nl.gn0s1s" %% "elastic4s-client-esjava" % "8.11.5",
  "nl.gn0s1s" %% "elastic4s-core" % "8.11.5"
)

当我尝试运行

sbt run

时，出现错误

sbt.librarymanagement.ResolveException: Error downloading nl.gn0s1s:elastic4s-client-esjava_3:8.11.5 NOT FOUND

。我已验证此处存在软件包和版本：https://mvnrepository.com/artifact/com.sksamuel.elastic4s/elastic4s-client-esjava和https://mvnrepository.com/artifact/com.sksamuel .elastic4s/elastic4s-core。我想知道我的设置或配置是否不正确。在添加 ElasticSearch 库依赖项之前，该项目运行良好（仅使用 postgres 依赖项）。

任何有关如何解决此问题的帮助将不胜感激！完整的错误日志如下供参考：

Answer 1

是的，抱歉没说清楚。似乎在某个时间点，图书馆从 sksamuel 更换了所有者；谁使用了

com.sksamuel.elastic4s

到 Philippus 的域名/组织；谁正在使用该域名/组织

nl.gn0s1s

。
（IIRC，这实际上是最近的事，但自从我查看任何与 ElasticSearch 相关的内容以来已经有一段时间了）.

因此，较新的版本位于

nl.gn0s1s

空间：https://mvnrepository.com/artifact/nl.gn0s1s/elastic4s-core，旧版本位于

com.sksamuel.elastic4s

空间：https://mvnrepository .com/artifact/com.sksamuel.elastic4s/elastic4s-core

因此，您可以使用最新版本：

8.15.3

在

nl.gn0s1s

空间中发布。
或者使用您最初发布的版本；

8.11.5

，但是将空格改为

com.sksamuel.elastic4s

恕我直言，最好使用最新版本，但您可能正在遵循“过时的”教程，因此坚持使用该教程的版本可能会更容易。
