I have a scala project and I want to import a dependency from another private repo (GitLab package registry) using SBT not using MAVEN or Gradle .. a bit lost and don't know where to start.
I already researched about it and don't know where to start.

I'm getting started with scala word (coming from java)
I'm trying to find some dependencies to add to my build.sbt, however, I cannot find an sbt repository (like mvn repo ), I tried this one but It doesn't work,
You can find sbt dependencies in maven repository itself. If there is a sbt dependency available for a given library or pacakge, then it will be mentioned like this under the SBT tab.
I have been using sbt on windows and a custom build.sbt script in conjunction with an import Chisel._ in the top-level file in order to generate Verilog from my Chisel source successfully.
I'm trying to get an IDE working on Windows to expedite Chisel development. I've gone with the Eclipse based SCALA IDE http://scala-ide.org/download/sdk.html/
I want to compile the Chisel library so that the import Chisel._ can be resolved locally, without having to go off and download the source from the repository each timeand recompile the source. When I download the Chisel-master repo from Git and include the src\main folder in my SCALA project in the SCALA IDE, I get lots of syntax errors in the Chisel SCALA files that prevent me from building the project.
Has anyone done anything like this before on Windows or have any knowledge of working with the SCALA IDE as it may just be a case of undefined symbols in the project configuration?
Not sure exactly what you did with build.sbt respect to recompile (I think it download it only the first time, then it caches it for the future). But I'm using ScalaIDE for Chisel on linux, using the default build.sbt files, maybe you can try to get it working out of the box first to help narrow down the issue.
Here are the steps I took in order to get ScalaIDE work with Chisel:
the latest Scala IDE uses 2.11.8, the current Chisel repository defaults to 2.11.7. So I had to change all the build.sbt reference to scalaVersion from 2.11.7 to 2.11.8
I used sbteclipse

To create importable the workspace to setup the compilation dependencies.
Except for chiselFrontEnd. For some reason, this package is not added to the dependency. I have to Add chiselFrontEnd as a javabuildpath dependency manually (Properties/JavaBuildPath, under Projects) for my own projects.
To resolve undefined symbols, you can also add a JAR onto the project build path using Project Properties > Java Build Path > Libraries > Add External JARs...
If you are getting your JARs through Maven / SBT, they should be in:
C:\Users\<name>\.ivy2\local\edu.berkeley.cs\chisel3_2.11\jars
If you are using publish-local with chisel3, your JARs should be in
C:\Users\<name>\.ivy2\cache\edu.berkeley.cs\chisel3_2.11\jars
Note that chisel3 is compiled into one JAR, including coreMacros and chiselFrontend sub-projects
Of course, this is a more quick-and-dirty solution compared to something that can parse SBT files.
I am trying to use scalaCheck (https://github.com/rickynils/scalacheck) to a gradle project. However, adding it this way:
dependencies {
...
compile group: 'org.scalacheck', name: 'scalacheck_2.11', version: '1.12.5'
...
}
doesn't seem to be doing the trick. I also tried to add it in a maven project. In both cases, trying to do the following
import org.scalacheck.Prop.forAll
reports the error
object scalacheck is not a member of package org
I ran "gradle dependencies" before trying to import it, and it seemed to download everything just fine, finishing the command without throwing errors. Is there a way to add scalacheck to my project and if so, how?
Note: not sure if relevant, but I am using Eclipse Neon with all the scala plugins.
(So it seems the problem was with using the eclipse gradle integration.) You have to manually update the project by using the Gradle | Refresh Gradle Project from the project's context menu on each dependency change (though it might be useful to do that on each change to gradle configuration files).
I want to use phantom with my scala IDE.So for this i clone the git hub repository and created a .jar file of phantom using sbt -> compile -> package.I add this .jar file to build path in my Scala IDE but still while importing
import com.websudos.phantom.connectors._
is throwing error that
object connector is not a member of com.websudos.phantom.
While using auto complete function of scala ide it is showing only the import for
import com.websudos.phantom.example
.I don't know if the jar files got created for example then why it is not created for other.
I search in internet but all other option are given as to add dependency in sbt build path but i dont want to use it.
Use sbt-assebly instead to create a fat jar.
https://github.com/sbt/sbt-assembly
I'm trying to create a standalone jar file from the elastic4s sources on github. I've used sbt compile as detailed on the github page, but I can't find the jar file.
How do I use sbt to create the jar file so I can import it into my projects as a dependency?
The compile task will only compile the project.
> help compile
Compiles sources.
If you want to create a jar file and use it as a dependency in your project, you have two ways of doing that.
Unmanaged dependency (not recommended)
Unmanaged dependency run +package, which will create a jar file for each supported scala version, which you can use in your projects as an unmanaged dependency. Copy the package-generated jar to lib folder in your project.
The jar files will be located in target/scala-2.11 and target/scala-2.10, depending on the Scala version you want to use it with.
Publish to Local Repository (recommended yet imperfect)
If you want to include your custom-built elastic4s, as a managed dependency, you have to run +publishLocal. This will do the same as above, but additionally it will publish the artifact to your local repository. Assuming you've built it with version := "1.2.1.1-SNAPSHOT", you can include it in your project by just adding:
libraryDependencies += "com.sksamuel.elastic4s" %% "elastic4s" % "1.2.1.1-SNAPSHOT"
What makes the approach imperfect is that once you shared the project on GitHub (or any other project sharing platform), people will have to do publishLocal themselves to be able to build your project. The dependency should therefore go to one of the official binary repositories so when a dependency is needed, it's downloaded from Internet. Consult Publishing.
What is the + character in front of the commands
The + in the commands is for cross-building, if you don't use it the command will be executed only using scalaVersion declared in the build.sbt of the project.
