I have a problem, I want to build my scala project with sbt.
I have scala 2.11.8, sbt about print
[info] Loading project definition from /home/xxx
[info] Set current project to base (in build file:/home/xxx)
[info] This is sbt 0.13.8
[info] The current project is {file:/home/xxx}
[info] The current project is built against Scala 2.11.8
[info]
[info] sbt, sbt plugins, and build definitions are using Scala 2.10.4
but still, when I run sbt compile I have exception with :
[error] during phase: typer
[error] library version: version 2.10.4
[error] compiler version: version 2.10.4
can someone help me?
Thanks
EDIT Forgot build.sbt file
build.sbt
name := "myproject"
version := "0.1"
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
"io.jvm.uuid" %% "scala-uuid" % "0.2.1",
"org.scala-lang.modules" %% "scala-parser-combinators" % "1.0.4",
"org.scalatest" % "scalatest_2.11" % "2.2.6" % "test",

"org.scalacheck" %% "scalacheck" % "1.13.0" % "test"
)
I don't have any build.scala for this project
For Fedora 23. I initially installed sbt with the bintray repository. I had to remove it and re install sbt without the bintray repo.
I was not working so I re-re installed sbt avec bintray repository and it works. Some configuration somewhere was messed up I think...

Few points I want to mention here regarding the SBT dependencies issues are:
Please add scalaVersion := "2.12.11" in build.sbt file like this, which includes the Scala version in your SBT dependencies automatically due to this%%.
name := "flink-streaming-demo"
scalaVersion := "2.12.11"
val flinkVersion = "1.10.0"
libraryDependencies += "org.apache.flink" %% "flink-scala" % flinkVersion % "provided"
libraryDependencies += "org.apache.flink" %% "flink-streaming-scala" % flinkVersion % "provided"
If you want Scala version specific SBT dependencies then use % like this:
libraryDependencies += "org.apache.flink" % "flink-scala_2.12" % flinkVersion % "provided"
libraryDependencies += "org.apache.flink" % "flink-streaming-scala_2.12" % flinkVersion % "provided"
In worst case if all these does not work then simply delete or rename these existing .sbt and .ivy2 hidden folder in your system home directory, where your all dependecies and plugins get sotred after downloading from maven central and then refresh/build the SBT project.
SBT dependency format
libraryDependencies += groupID % artifactID % revision % configuration
Meaning of % and %%
%: A method used to construct an Ivy Module ID from the strings you supply.
%%: When used after the groupID, it automatically adds your project’s Scala version (such as _2.12) to the end of the artifact name.

summing up the comments since perhaps it is a bit hard to know what you should do
In general, if you get an "Unresolved dependencies" error, look at mvnrepository.com, search for your artifact:
https://mvnrepository.com/artifact/org.apache.flink/flink-scala
This tells you (second column) which Scala versions are supported by it. In this case, the library is available for 2.11.x and 2.12.x.
Thus, you have to use a Scala version compatible with that in your build, in build.sbt:
ThisBuild / scalaVersion := "2.12.10"
I'm trying to use log4j2 in scala.
Below is my build.sbt
name := "trial"
version := "0.1"
scalaVersion := "2.13.1"
libraryDependencies += "org.apache.logging.log4j" %% "log4j-api" % "2.12.1"
libraryDependencies += "org.apache.logging.log4j" %% "log4j-core" % "2.12.1"
libraryDependencies += "org.apache.logging.log4j" %% "log4j-api-scala" % "2.12.1"
How to resolve these errors:
[warn] Note: Unresolved dependencies path:
[error] sbt.librarymanagement.ResolveException: Error downloading org.apache.logging.log4j:log4j-api_2.13:2.12.1
sbt.librarymanagement.ResolveException: Error downloading org.apache.logging.log4j:log4j-api_2.13:2.12.1
not found: /Users/username/.ivy2/local/org.apache.logging.log4j/log4j-api_2.13/2.12.1/ivys/ivy.xml
Note :
There is no directory /Users/username/.ivy2/local/
but I can see there is /Users/username/.ivy2/cache/
and plugins log4j-api,core,api-scala are present in cache.
The IDE i'm using is IntelliJ IDEA.
There are multiple problems
You are using Scala 2.13 however the latest build of log4j-api-scala is for Scala 2.12.
The latest version of log4j-api-scala is 11.0 not 2.12.1
log4j-api and log4j-core are Java libraries so we should use single % instead of double%%
I'm developing a Spark process in Scala (Eclipse IDE) and runs fine in my local cluster, but when I try to compiled it with SBT that I installed on my pc I got a error (see picture).
My first doubt is why SBT try to compile with scala 2.12 if I explicitly set scalaVersion to 2.11.11 in my build.sbt. I tried installing other SBT versions with the same results, also in other PCs but not works. I need help to fix it.
scala_version(Spark) :2.11.11
sbt_version : 1.0.2
spark: 2.2
build.sbt
name := "Comple"
version := "1.0"
organization := "com.antonio.spark"
scalaVersion := "2.11.11"

assembly.sbt
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "1.0.2")
Error:
ResolveException: unresolved dependency: sbt_assembly;1.0.2: not found
Try changing your assembly.sbt file to:
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.5")
as stated in the documentation here: https://github.com/sbt/sbt-assembly
I recently used that with spark-core_2.11 version 2.2.0 and it worked.
I'm new to Scala and working with IntelliJ Community Edition.
I open a new project and edit the build.sbt file to contain the following:
name := "test"
version := "1.0"
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
"org.locationtech.geotrellis" %% "geotrellis-raster" % "1.0.0" % "1.1.0" ,
"org.locationtech.geotrellis" % "geotrellis-shapefile_2.11" % "1.1.0"
).map(_
.exclude("com.azavea.geotrellis", "geotrellis-proj4_2.11")
.exclude("com.azavea.geotrellis", "geotrellis-raster_2.11")
)
After that, I refresh the project, and I get the following errors in the error file:
[error] (*:ssExtractDependencies) java.lang.IllegalArgumentException: Cannot add dependency 'org.locationtech.geotrellis#geotrellis-raster_2.11;1.0.0' to configuration '1.1.0' of module default#test_2.11;1.0 because this configuration doesn't exist!
[error] (*:update) java.lang.IllegalArgumentException: Cannot add dependency 'org.locationtech.geotrellis#geotrellis-raster_2.11;1.0.0' to configuration '1.1.0' of module default#test_2.11;1.0 because this configuration doesn't exist!
What am I doing wrong here?
Main issue seems to be two different version numbers on one of your dependencies.
"org.locationtech.geotrellis" %% "geotrellis-raster" % "1.0.0" % "1.1.0"
Should be
"org.locationtech.geotrellis" %% "geotrellis-raster" % "1.0.0"
or
"org.locationtech.geotrellis" %% "geotrellis-raster" % "1.1.0"
if you want the 1.1.0 version
What I have so far:
.bashrc
2 PATH=/opt/scala-2.9.1.final/bin:$PATH
3 PATH=/opt/sbt:$PATH
So my scala-2.9.1.final version is in the /opt folder. The same goes with sbt 0.10.
I'm trying to get it to pick my 2.9.1.final instead of 2.8 whatever. I've tried looking.
What i've done so far is putting symbolic links in projectname/boot/ directory.
ln -s /opt/scala-2.9.1.final scala-2.9.1.final
But it doesn't seem to work? I've also tried this build.sbt (https://github.com/VonC/xsbt-template/blob/master/build.sbt) and change the version to 2.9.1.final.
How do I get sbt>console to use 2.9.1.final? And how does it build using 2.9.1.final?
This is what I get when I type sbt:
user#acomputer:~/project/sbt$ sbt
[info] Set current project to default-295917 (in build file:/home/user/project/sbt/)
>
Thank you for your time.
I'm not experienced sbt user and may only suggest. Seems sbt 0.10.x use scala 2.8.1 itself, so I think sbt console is working by default with this version.
But you can build project with targetting on 2.9.1 by specify scala version in you build.sbt file: `scalaVersion := "2.9.1"' (see https://github.com/harrah/xsbt/wiki/Setup "ConfigureBuild")
And also you can switch scala version used by sbt console by typing "++ 2.9.1" in sbt prompt. (see https://github.com/harrah/xsbt/wiki/Running)
Here's an example of an build.sbt in one of my projects.
organization := "com.andyczerwonka"
name := "esi.intelligence"
version := "0.1"
scalaVersion := "2.9.1"
retrieveManaged := false
logLevel := Level.Info
jettyScanDirs := Nil
seq(webSettings :_*)
temporaryWarPath <<= (sourceDirectory in Compile)(_ / "webapp")
libraryDependencies ++= {
val liftVersion = "2.4-M4"
Seq(
"net.liftweb" %% "lift-webkit" % liftVersion % "compile->default",
"net.liftweb" %% "lift-mapper" % liftVersion % "compile",
"org.eclipse.jetty" % "jetty-webapp" % "7.3.0.v20110203" % "provided,jetty",
"junit" % "junit" % "4.8" % "test",
"ch.qos.logback" % "logback-classic" % "0.9.26",
"org.specs2" %% "specs2" % "1.6.1" % "test",
"net.databinder" %% "dispatch-http" % "0.8.5",
"com.h2database" % "h2" % "1.2.138"
)
}
Notice the 4th line. This tells sbt that I want to use 2.9.1. sbt will bring it down for me and use it.
