执行sbt命令时卡在获取org.scala-sbt包的问题求助

执行sbt命令已超过2小时，始终停留在「[info] [launcher] getting org.scala-sbt sbt 0.13.16 (this may take some time)...」状态，请求技术支持。

排查与解决步骤 #

• 清理SBT缓存
  删除SBT的boot缓存目录，强制触发重新下载：

  rm -rf ~/.sbt/boot
  

  执行完成后重新运行sbt命令。

• 配置镜像仓库加速
  若网络访问官方仓库缓慢，在~/.sbt/repositories文件中添加国内镜像（如阿里云）：

  [repositories]
  local
  aliyun: https://maven.aliyun.com/repository/public
  typesafe: https://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
  sonatype-oss-releases
  sonatype-oss-snapshots
  

  保存后重新执行sbt。

• 统一SBT版本
  日志显示项目尝试加载sbt 0.13.16，但本地安装的是1.7.1，版本不匹配导致冲突。在项目根目录的project/build.properties中指定与本地一致的版本：

  sbt.version=1.7.1
  

• 调整JVM内存参数
  编辑~/.sbtopts文件，增加内存分配避免解析依赖时内存不足：

  -Xms2048m
  -Xmx2048m
  -XX:ReservedCodeCacheSize=256m
