无法导入本地发布的 Scala 插件

Question

我有一个项目，我作为插件在本地发布到我的 .m2 目录，稍后我需要将其导入到不同的 Scala 项目中并使用它。 似乎发布步骤已正确执行。 插件项目的build.sbt文件如下所示：

lazy val root = (project in file("."))
  .enablePlugins(SbtPlugin)
  .settings(
    name := "pluginName",
    organization := "com.myOrg",
    pluginCrossBuild / sbtVersion := {
      scalaBinaryVersion.value match {
        case "2.12" => "1.4.6" // set minimum sbt version
      }
    }
  )

resolvers += "confluent" at "https://packages.confluent.io/maven"

libraryDependencies ++= Seq(
      "io.confluent"    % "kafka-schema-registry-client" % "7.0.1"
      // some other dependemcies
    )

在 sbt shell 中运行 compile 和 publishLocal 命令后，我收到下一条消息：

[info]  delivering ivy file to /Users/me/Work/repos/external/pluginName/target/scala-2.12/sbt-1.0/ivy-1.0.0.xml
[info]  published pluginName to /Users/me/.ivy2/local/com.myOrg/pluginName/scala_2.12/sbt_1.0/1.0.0/poms/pluginName.pom
[info]  published pluginName to /Users/me/.ivy2/local/com.myOrg/pluginName/scala_2.12/sbt_1.0/1.0.0/jars/pluginName.jar

[success] Total time: 0 s, completed 3 Jan 2022, 10:07:43

为了在另一个 Scala 项目中导入/安装这个插件，我在plugins.sbt 文件中添加了下一行：addSbtPlugin("com.myOrg" % "pluginName" % "1.0.0") 我还在buid.sbt 文件的externalResolvers 部分添加了libs-release-local 和libs-snapshot-local。

重新加载和编译项目后，我收到此错误：

    [error] (update) sbt.librarymanagement.ResolveException: Error downloading io.confluent:kafka-schema-registry-client:7.0.1

[error]   not found: https://repo.typesafe.com/typesafe/ivy-releases/io.confluent/kafka-schema-registry-client/7.0.1/ivys/ivy.xml

我对 Scala 有点陌生，我不明白我做错了什么。 谁能解释一下这个问题？

您正在发布到本地 Maven 缓存，但 sbt 使用 Ivy。

尝试删除publishTo 设置，它应该不需要。只需使用publishLocal 任务即可发布到本地 Ivy 缓存。
