I'm new to Scala and SBT so I might be missing something obvious.
I was trying to compile the HelloWorld example on http://www.scalafx.org/docs/quickstart/
I created a file build.sbt containing:
scalaVersion := "2.11.5"
libraryDependencies += "org.scalafx" %% "scalafx" % "8.0.0-R4"
and a file src/main/scala/ScalaFXHelloWorld.scala containing the code from linked page.
However, when running sbt run I get:
OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256M; support was removed in 8.0

I'm running sbt 0.13.7 and scala 2.11.5 on openjdk 1.8.0_31 on Archlinux
JavaFX isn't part of OpenJDK 8. I installed openjfx. Works. (Thanks Jasper)

I am using spark with Kubernetes and facing an issue while building a fat jar with "sbt assembly" command with libraryDependencies += "org.apache.spark" %% "spark-kubernetes" % "2.4.5" in my build.sbt. Everything is working fine if i downgrade the spark kubernetes version to "2.4.2" but not with "2.4.5".`
And in another case when i rebuild the same code again using sbt assembly after deleted the target folder generated by previous sbt assembly command then it starts working fine with the same 2.4.5 spark Kubernetes jar.
I just want to avoid this multiple times assembly jar building activity and i have also tried by adding spark tags library in my build.sbt file but still it is not working.
So Please help me with this issue.
I am using spark 2.4.4 and scala 2.11.12 and sbt 1.2.8
Kindly find the attached logs .

I did add the scala-library.jar to the classpath but to no avail. Does anyone know what might be missing?
Ps. used -> new SBT project (Intellij) on osx
edit: here's the build.sbt
name := "test"
version := "1.0"
scalaVersion := "2.11.8"
resolvers += "Scales XML" at "https://mvnrepository.com/artifact/org.scalesxml/scales-xml_2.9.1"
libraryDependencies += "org.scalesxml" % "scales-xml_2.9.1" % "0.3-RC7"
SBT is version 0.13.8
Edit 2:
Figured it out. I was trying to run a class (with a main method) without creating an instance... After changing it to an Object things work a lot better :)
Edit 3:
Spoke too soon. I turns out it has to do with setting the scalaVersion in build.sbt. When I leave that entire line out, it no longer complains about the missing dependencies. When I put it back in I get the errors mentioned above back. I tried setting it to 2.11.7 as well ( after installing that with brew install scala) but to no avail.
scalaVersion := "2.11.8"
libraryDependencies += "org.scalesxml" % "scales-xml_2.9.1" % "0.3-RC7"
You can't use a library compiled for Scala 2.9.1 with Scala 2.11.*. Write "org.scalesxml" %% "scales-xml" % some-version instead, which will look for scales-xml_2.11. See http://www.scala-sbt.org/0.13/docs/Cross-Build.html.
Every now and then I start things from scratch to make sure I know what all the intricate details of setting up a project are. I have a simple app like the following but I get some dependency issues that don't seem to point me anywhere. I'm using scala verions 2.11.

My main App is just a println for now. It's not even calling this actor.
Am I using the wrong version of akka with scala 2.11? -Ylog-classpath didn't help
Don't know what fixed it but here's a list of things I did and the project compiles now.
Changed akka dependency line to this (added double percent and changed version back to 2.4)
libraryDependencies ++= Seq(
"com.typesafe.akka" %% "akka-actor" % "2.4.0"
)
Removed my Run configuration and added it back again. ( I think the path to main showed as red (invalid) so redoing it helped resolve it. I changed my package name and I don't think intelliJ picked up the rename well in build-conf)
Started another test project from IntelliJ menu (Akka Main in Scala) and that took a bit to download all dependencies. So maybe my project needed those and wasn't download them?
Removed commented out lines (got rid of a semi-colon). I don't think this did anything but full disclosure, technically I did touch the code even though my actor definition is exactly the same.
I'm starting a new project using Scalatra and when trying to build the process the compiler says:

As suggested by #richard-close, the issue was caused in my case by having a jdk7 used by sbt.
You can check that with
