stay Chisel During the learning process, I found that the learning efficiency was limited by the network speed , foreign maven Source number KB/S The speed of is really affecting the efficiency , So it took time to test and get the relevant source replacement method , Respectively for VS Code Medium scala metals plug-in unit 、sbt and courier.

1. VS Code in scala metals Plug in source change

   Add a custom warehouse directly in the settings ：

   https://maven.aliyun.com/repository/central

   cd  ~
   mkdir  .sbt
   cd  .sbt
   

   establish repositories file ：

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

   Modify the configuration file ：

   sudo vi /usr/share/sbt/conf/sbtopts
   

   Add at the end of the file ：

   -Dsbt.override.build.repos=true
   

3. coursier Source change （ In the build Chisel-bootcamp Local Notebook When using ）

   export COURSIER_REPOSITORIES="https://maven.aliyun.com/repository/public|https://maven.scijava.org/content/repositories/public"
   

   The following is used to replace the corresponding part of the installation steps ：

   ./coursier bootstrap -i user -I user:sh.almond:scala-kernel-api_$SCALA_VERSION:$ALMOND_VERSION     sh.almond:scala-kernel_$SCALA_VERSION:$ALMOND_VERSION     --sources --default=true     -o almond
