SBT依赖解析失败：克隆多模块项目遇grpc依赖校验错误

问题 #

从云仓库克隆了一个带assembly的多模块SBT项目，构建时遇到依赖解析失败：io.grpc:grpc-core:1.25.0和io.grpc:grpc-api:1.25.0找不到，本地.ivy2仓库无对应依赖，同时Coursier缓存的元数据校验和错误。添加自定义resolvers后问题仍未解决，且IDE中各模块的蓝色方块也无法正常显示，此前该代码可正常运行。

已添加的Resolvers配置 #

resolvers ++= Seq("io.grpc" at "https://mvnrepository.com/artifact/io.grpc/grpc-core",
  "io.grpc" at "https://mvnrepository.com/artifact/io.grpc/grpc-api")

解决方案 #

• 清理损坏的缓存
  校验和错误是缓存文件损坏导致的，直接删除对应缓存目录：

  • 删除Coursier缓存：C:\Users\eksinvi\AppData\Local\Coursier\cache
  • 删除Ivy2本地仓库：C:\Users\eksinvi\.ivy2\local
    或者用SBT命令一键清理：sbt clean cleanFiles

• 修正Resolvers配置
  之前配置的resolves地址错误，mvnrepository是依赖查询网站，不是合法的Maven仓库源。替换成标准仓库：

  resolvers ++= Seq(
    "Maven Central" at "https://repo1.maven.org/maven2/",
    "Google Maven" at "https://maven.google.com/"
  )
  

  不需要为单个依赖单独配置仓库，只要仓库包含所需依赖即可。

• 强制重新拉取依赖
  清理缓存后，运行sbt update命令，强制SBT重新解析并下载所有依赖，避免缓存残留问题。

• 修复IDE模块显示问题
  模块蓝色方块不显示是IDE未同步项目，执行以下操作：

  1. 打开IDE的File -> Invalidate Caches...选项
  2. 勾选"Invalidate and Restart"，重启IDE后重新导入项目
