本文档介绍了如何配置SBT的~/.sbt/repositories文件以使用不同的远程镜像，包括本地Nexus私服和阿里云镜像。同时，展示了在build.sbt中设置依赖的正确格式，区分了'%%'和'%'的使用。在解决依赖下载错误的过程中，提到了Scala版本对依赖路径的影响，并提供了一个完整的build.sbt示例。

~/.sbt/repositories 远程镜像

若没有默认访问https://repo1.maven.org/maven2
也可修改:~/.sbt/repositories

[repositories]
local    ##表示本地路径~/.ivy2
my-nexus: https://127.0.0.1:8081/nexus/public/  ## 指向本地搭建的nexus 私服
aliyun: http://maven.aliyun.com/nexus/content/groups/public/ ## 指向阿里云镜像
typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
sonatype-oss-releases
maven-central  ## 默认maven ，maven-central 属于sbt 内置变量
sonatype-oss-snapshots

sbt 代理设置 https://www.scala-sbt.org/1.x/docs/Proxy-Repositories.html

build.sbt 依赖格式

libraryDependencies += "com.google.code.gson" % "gson" % "2.9.1"

死活不对报错，发现依赖格式错误

[error] (update) sbt.librarymanagement.ResolveException: Error downloading com.google.code.gson:gson_2.11:2.9.1
[error]   Not found
[error]   Not found
[error]   not found: https://repo1.maven.org/maven2/com/google/code/gson/gson_2.11/2.9.1/gson_2.11-2.9.1.pom
[error]   not found: https://maven.aliyun.com/repository/public/com/google/code/gson/gson_2.11/2.9.1/gson_2.11-2.9.1.pom

buildsbt %% 和% 的区别

libraryDependencies += "com.google.code.gson" %% "gson" % "2.9.1"

%%表示带上scala的version com/google/code/gson/gson_2.11/2.9.1

libraryDependencies += "com.google.code.gson" % "gson" % "2.9.1"

% 表示不带scala version com/google/code/gson/gson/2.9.1

参见 sbt 文档
在这里插入图片描述
完整的build.sbt

ThisBuild / version := "1.0"
ThisBuild / scalaVersion := "3.11.12"
ThisBuild / organization := "mi.com"

resolvers += DefaultMavenRepository

val spinalVersion = "1.7.2"
val spinalCore = "com.github.spinalhdl" %% "spinalhdl-core" % spinalVersion
val spinalLib = "com.github.spinalhdl" %% "spinalhdl-lib" % spinalVersion
val spinalIdslPlugin = compilerPlugin("com.github.spinalhdl" %% "spinalhdl-idsl-plugin" % spinalVersion)

lazy val mylib = (project in file("."))
  .settings(
    name := "misoc",
    libraryDependencies ++= Seq(spinalCore, spinalLib, spinalIdslPlugin,
      "org.apache.poi" % "poi" % "3.17",
      "org.apache.poi" % "poi-ooxml" % "3.17"
    )
  )
