使用Nexus代理的Scala sbt覆盖插件解决方案

Question

我在我的项目project/plugins.sbt中使用了scoverage插件

addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.5.1")

当我不使用我们的公司节点时，这可以很好地解决问题。

为了测试我在下面的~./sbt/repositories添加的nexus

[repositories]
    local
    maven-releases: https://repo.example.net/nexus/repository/proxy-central.maven.org/
    ivy-releases: https://repo.example.net/nexus/repository/proxy-repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
    sbt-plugin-releases: https://repo.example.net/nexus/repository/proxy-repo.scala-sbt.org/scalasbt/sbt-plugin-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]

我删除了~./ivy2/cache，当我尝试编译时：

[warn] ==== maven-releases: tried

    [warn]      org.scoverage:sbt-scoverage:1.5.1 (scalaVersion=2.12, sbtVersion=1.0)

我注意到sbt coverage有一个目录结构，其中包括scala和sbt版本：https://repo1.maven.org/maven2/org/scoverage/sbt-scoverage_2.12_1.0/1.5.1/sbt-scoverage-1.5.1.pom

我还试图更改project/plugins.sbt，但无济于事：

addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.5.1", scalaVersion="2.12", sbtVersion="1.0")

为什么我的maven代理没有从maven central下载这个插件(尽管它确实存在)，有什么原因吗？

注意:代理解析适用于ivy样式版本和其他maven版本。

编辑:注意I:无需使用代理(直接从maven central)即可解析工件。这就是我得出的结论，即代理配置中一定缺少了一些东西。任何/所有指针都会很有帮助。注II:其他工件的解决方案(包括sbt-assembly插件、sbt本身、scala-reflect等与我的代理完美配合)
