【问题描述】：

我已经按照 sbt 文档了解如何安装 sbt-eclipse 插件，但我一直在 sbt shell 中遇到错误。

我使用的是 Windows 10 Pro、sbt v1.3.3 和 Eclipse v4.7.0（在 ~\Documents\eclipse 中）。

我的 hello-world\build.sbt 文件非常简单：

scalaVersion := "2.13.1"
name := "hello-world"
organization := "ch.epfl.scala"
version := "1.0"
libraryDependencies += "org.typelevel" %% "cats-core" % "2.0.0"

而我的 hello-world\project\plugins.sbt 文件只有一行：

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.1.0")

sbt shell 中 eclipse 命令出错：

sbt:hello-world> eclipse
[error] Expected ';'
[error] Not a valid command: eclipse (similar: client, help, alias)
[error] Not a valid project ID: eclipse
[error] Expected ':'
[error] Not a valid key: eclipse (similar: deliver, licenses, clean)
[error] eclipse
[error]        ^

在 sbt shell 中编译时出错：

sbt:hello-world> compile

【参考方案1】：

使用最新版本的插件并重新开始。

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.2.4")
