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.

The files are in the repository. I copy paste paths from the console to file explorer and they are there.

The output:

[debug]          trying file://c:/Users/userz/.m2/repository/com/twitter/naggati/2.0.0/naggati-2.0.0.pom

[debug]                 tried file://c:/Users/userz/.m2/repository/com/twitter/naggati/2.0.0/naggati-2.0.0.pom

.0/naggati-2.0.0.jar

[debug]         Local Maven Repository: no ivy file nor artifact found for com.twitter#naggati;2.0.0

Edit: I added the path using scala file in project/build like described in http://code.google.com/p/simple-build-tool/wiki/LibraryManagement

"sbt can search your local Maven repository if you add it as a repository:"

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

That made sbt look in the local repository. Before it didn't.

So the scala file looks like this:

import sbt._

class Foo(info: ProjectInfo) extends DefaultProject(info) {

val mavenLocal = "Local Maven Repository" at "file://c:/Users/userz/.m2/repository"

}

(I hardcoded Path.userHome to exclude possible error reason. As expected it didn't change anything).

The repository is added, otherwise the script would not look there for the files. — User, May 27 '12 at 17:48
How is the line that tells sbt to look for your dependency? If you have something like ... -> default, remove default from there. — fmpwizard, May 27 '12 at 19:01
Actually I'm not using build.sbt. I'm using a scala file like described in http://code.google.com/p/simple-build-tool/wiki/LibraryManagement. Edited my post with more details. — User, May 27 '12 at 19:16
ixx: That's SBT 0.7.x, and it's the legacy version. You should update to [SBT 0.11.x])https://github.com/harrah/xsbt/wiki), if possible. — leedm777, May 28 '12 at 01:40

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

resolvers += Resolver.mavenLocal

Which sbt is that? I used it with 0.13.11 and it works just fine. – marios Oct 14 '16 at 20:23

`resolvers in Global := Resolver.mavenLocal` works for me. – retronym Oct 29 '17 at 23:39
OMG I've searched an hour for this perfect solution! Thx – Hartmut Pfarr Nov 10 '18 at 01:20
@retronym, I think you meant "resolvers in Global += Resolver.mavenLocal" – Ben McCann Mar 03 '19 at 03:07

For SBT 1.3.x it's `ThisBuild / resolvers += Resolver.mavenLocal` – antex Nov 26 '19 at 16:12

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"

not with projects defined and adding to the project doesn't work either – pferrel Aug 05 '17 at 22:38

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"

No matter what I do I still get this error when doing sbt compile: [warn] :::::::::::::::::::::::::::::::::::::::::::::: [warn] :: UNRESOLVED DEPENDENCIES :: [warn] :::::::::::::::::::::::::::::::::::::::::::::: [warn] :: com.sanoma.cda#maxmind-geoip2-scala_2.11;1.3.2: not found [warn] :::::::::::::::::::::::::::::::::::::::::::::: [trace] Stack trace suppressed: run last *:update for the full output.

I used `resolvers in Global += "Local Maven Repository" at "file://" + Path.userHome + "/.m2/repository"` – Carlos Ferreyra May 30 '20 at 23:35

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
  )

doesn't work for me, though it may have something to do with projects – pferrel Aug 05 '17 at 22:36

Thanks Dyin, It worked. Added resolver to commonSettings, now all defined projects can look into local maven repo for dependencies. – raevilman Oct 06 '17 at 07:27
