I created a new project using Play Scala and Eclipse. Added Squeryl dependency and see that it's been pulled during compile time. Confirmed it's present in .ivy2/cache/org.squeryl directory but eclipse project is not able to pull it up and causing compilation for import.
build.sbt
name := """registration"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayScala)
scalaVersion := "2.11.1"
libraryDependencies ++= Seq(
jdbc,
anorm,
cache,
ws,
"org.squeryl" % "squeryl_2.10" % "0.9.6-RC2"
)
It looks like squeryl doesn't have a binary readily available for Scala 2.11 yet according to http://www.squeryl.org/getting-started.html
So if you want to use a pre-compiled version of this library you must change your scala version to 2.10.4.
All versions of squeryl available can be found at: http://mvnrepository.com/artifact/org.squeryl
I had a similar case using eclipse.
Select Project --> Clean to clean your workspace and build it again if you have not checked "Build Automatically".
If its still not visible please refresh the package explorer (or just the 'Referenced Library') with F5.

Is there a standard in place for setting up a Scala project where the build.sbt is contained in a subdirectory?
I've cloned https://github.com/lightbend/cloudflow and opened it in IntelliJ, here is the structure:
Can see core contains build.sbt.
If I open the project core in a new project window then IntelliJ will recognise the Scala project.
How to compile the Scala project core while keeping the other folders available within the IntelliJ window?
EDIT:
If you do want to play around with the project, it should suffice to either import an SBT project and select core as the root. Intellij should also detect the build.sbt if you open core as the root.
Here is the SBT Reference Manual
Traditionally, build.sbt will be at the root of the project.
If you are looking to use their libraries, you should import them in your sbt file, you shouldn't clone the repo unless you intend to modify or fork their repo.
For importing libraries into your project take a look at the Maven Repository for Cloudflow, select the project(s), click on the version you want, and select the SBT tab. Just copy and paste those dependencies into your build.sbt. Once you build the project with SBT, you should have all those packages available to you.
So in [ProjectRoot]/build.sbt something along the lines of
val scalaVersion = "2.13.4"
lazy val root = (project in file("."))
.settings(
name := "Your_Project_Name",
scalaVersion := scalaVersion,
libraryDependencies += "com.lightbend.cloudflow" %% "cloudflow-streamlets" % "2.0.26-RC12",
// Either sequentially
libraryDependencies += "com.lightbend.cloudflow" %% "cloudflow-akka" % "2.0.26-RC12",
// Or as a sequence (note that you can have a trailing comma for these)
libraryDependencies ++= Seq(
"com.lightbend.cloudflow" %% "cloudflow-blueprint" % "2.0.26-RC12",
"com.lightbend.cloudflow" %% "cloudflow-flink" % "2.0.26-RC12", // No next elemenet
)
// Or combo using both like above, just don't forget the commas in between
)
I'm trying to create jar file from scala file - which will be used for Scalatron bot (http://scalatron.github.io/)
The problem is that if I create jar file using new scala versions 2.10 - 2.13 (these are the only one's that InteliJJ allows me to use) scalatron bot doesn't work.
However I found out that downgrading to scala 2.9.2 fixes the problem (Getting Scalatron to Work (trouble with opcode)).
How to downgrade to 2.9.2 on Intellij?
SBT is fully integrated with IntelliJ Idea, so you can create a SBT project in IntlliJ and make up the build.sbt file by yourself and put in it the scala version you want, compile, package and execute with SBT
name := "scalatron"
version := "0.1"
scalaVersion := "2.9.2"
libraryDependencies += "org.scalatest" %% "scalatest" % "3.2.0-SNAP3" % Test
I have a CLI app which compile only to 2.11 (because of some internal dependency).
I want to package this app as a sbt plugin. This sbt plugin run the app by forking the JVM, running separately with its own classpath to avoid Scala library conflict.
Obviously I need to download the scala 2.11 app with all its dependencies and I am using a custom Configuration for it. My issue is that when I try to list the dependencies it comes with the scala library configured by the project.
Specific code is here : https://github.com/thibaultdelor/CliAppSbtPlugin/blob/master/plugin/src/main/scala/com/thibaultdelor/MyWrapperPlugin.scala#L33
autoScalaLibrary in CliConfig := false,
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-library" % "2.11.12" % CliConfig,
"com.thibaultdelor" % "mycli_2.11" % "0.0.1" % CliConfig
)
val dependencies = (update in CliConfig).value.select(configurationFilter(CliConfig.name))
Here, if the project has the scala version 2.12, dependencies will contains scala-library 2.12 instead of what 2.11 as I would like.
Any help welcome, I am stuck. The sample project is on github and has a failing test case for it.
I am very new to SBT, Breeze and IntelliJ, though I have a decent grasp of Scala and I am trying to install the Breeze library, which I think is managed.
What I've done:
I followed the instructions on this page and added this script to the build.sbt file in my project:
libraryDependencies ++= Seq(
// other dependencies here
"org.scalanlp" %% "breeze" % "0.10",
// native libraries are not included by default. add this if you want them (as of 0.7)
// native libraries greatly improve performance, but increase jar sizes.
"org.scalanlp" %% "breeze-natives" % "0.10"
)
resolvers ++= Seq(
// other resolvers here
"Sonatype Releases" at "https://oss.sonatype.org/content/repositories/releases/"
)
// Scala 2.9.2 is still supported for 0.2.1, but is dropped afterwards.
scalaVersion := "2.11.1" // or 2.10.3 or later
I then ran sbt update in the project directory (via the terminal), and saw that all the pieces of Breeze downloaded.
I then tried re-running sbt update, but this did not trigger another download.
Issue:
The problem is that I cannot access the library via IntelliJ. import breeze._ gives the standard Cannot resolve symbol breeze and I couldn't find any mention of Breeze in "Project Structure." It isn't in the lib directory of the project either.
Am I missing a step?
Sounds like a bug in the IntelliJ project, try removing the .idea directory from the project directory and then re-import the project into IntelliJ using the wizard.
I am trying a very simple sbt example; when I compile it with sbt, and always get the following error:
org.scala-sbt#sbt_2.9.1;0.12.3: not found
I found a build.properties file under project folder, where I could change the 0.12.3 part; for example, after I changed it to 0.11.3, it will succeed until another inompatible issue; However, I want to know how to change sbt_2.9.1 to, say, sbt_2.9.2; I don't find a configuration file, and even I update the sbt to the latest version 0.12.3, still no luck.
my build.sbt file:
organization := "com.typesafe.slick"
name := "slick-examples"
version := "1.0.1-RC1"
scalaVersion := "2.10.1"
scalacOptions += "-deprecation"
anyone please help me.
The Scala version sbt is using internally and the one used for your project are totally independent. Which sbt launcher are you using? Make sure you are using an sbt.version property that works for your sbt launcher.
Again, no need to configure the Scala version for your project at that level. Write a build.sbt file and set scalaVersion to, e.g. 2.10.1 (assuming you use sbt 0.12.x): scalaVersion := 2.10.1
