SBT doesn't find file in local maven repository although it's there

Question

I\'m having problems with a maven dependency which is in my local respository.

SBT can\'t find it. Already set log level to debug, but not getting anything new.

Answer 1

You need three slashes after the file: specifier. This is because between the second and third slash, you have an optional hostname. Wikipedia has a good explanation of file: URL's

You're having a problem because the typical pattern of "file://"+Path.userHome+"/.m2/repository" assumes a Unix filesystem, where the path begins with a /, contains no :, and usually contains no spaces.

To have a non-hardcoded path that works on both Windows and Linux/Unix, use:

"Local Maven" at Path.userHome.asFile.toURI.toURL + ".m2/repository"

Answer 2

Watch out when you have a project defined, you'll need to include the resolver in the settings. Global resolver will not be identified.

Example:

lazy val core = (project in file("core")).
  settings(commonSettings: _*).
  settings(
    resolvers += Resolver.mavenLocal,
    name := "Core",
    libraryDependencies := coreDependencies
  )

Answer 3

To get this to work for newer versions of sbt, add the following to build.sbt:

resolvers += "Local Maven Repository" at "file:///"+Path.userHome+"/.m2/repository"

Answer 4

Just add this line in the build.scala or build.sbt file

resolvers += Resolver.mavenLocal
