With scala 2.12.4 when I use theses parameters
scalacOptions := Seq("-unchecked", "-deprecation", "-opt:l:inline","-opt-inline-from:bfd.DateTime$","-Yopt-log-inline")
I have error which doesn't exist when I don't use "-Yopt-log-inline"

I think the error is not related to the usage of inline. Maybe the options override the scala dependency definition.
Is it a bug in the compiler or just a bad setting with an unclear feedback?
-Yopt-log-inline expect a parameter. The equivalent to the wild card of -opt-inline-from:** is the underscore _.
So to correct this error add this parameter to scalacOptions like this.
scalacOptions ++= Seq("-opt:l:inline","-opt-inline-from:bfd.DateTime$","-Yopt-log-inline", "_")
edit:
What hepping here is a problem between scalac and sbt, sbt gives the class pass next to Scala option, so scalac think the classpath is the option of -Yopt-log-inline and start without actual classpath, which make a crach.
If you are using sbt and don't want to fall in this kind of error you can use "-Y" as your last option.

I'm trying to build https://github.com/gatling/gatling but the compilation fails. The steps I undertook:
Installed sbt using the documentation.
Clone the github project.
Execute sbt compile in the directory gatling.
I get the following error:

I do not know enough of scala to debug this, how can I fix this?
Try IntelliJ Idea with scala plugin
Just use IntelliJ Idea open the project folder
I've executed as sudo (sudo sbt compile) and now the compilation is succesful.
I am trying to call some clojure code as a sbt task.
My build.sbt looks like,
lazy val aTask = taskKey[Unit]("a task")
libraryDependencies ++= Seq(
"org.clojure" % "clojure" % "1.9.0"
)
import clojure.java.api.Clojure
import clojure.lang.IFn
aTask := {
val plus: IFn = Clojure.`var`("clojure.core", "+")
println(plus.invoke(1, 4))
}
Contents of project/build.sbt
resolvers += Resolver.mavenLocal
libraryDependencies ++= Seq(
"org.clojure" % "clojure" % "1.9.0"
)
Also I have added clojure dep in project/build.sbt of my project.
I am getting the following error when calling the task

Any pointers on what I could try would be helpful.
I think there is an issue with class loaders setup by sbt. Clojure's RT class loads Clojure namespaces/classes using class loaders API. If sbt configures the classloaders hierarchy and class loading strategy (e.g. parent first) in a way that RT's classloader doesn't find Clojure's classes via classloader it's using then it will fail with the error you are getting.
Unfortunately, I don't know sbt internals to determine how the classloaders get configured. Maybe another question would help in the investigation: How to display classpath used for run task?
While upgrading from play 2.4 -> 2.5 I hit an issue where
Symbol 'type <none>.iteratee.Iteratee' is missing from the classpath
I checked the migration guide and included the dependency "com.typesafe.play" % "play-iteratees_2.11" % 2.5.18 into sbt. From the new play-iteratees repo, I was under the impression that package play.api.libs.iteratee is where I'd find what to import. But it doesnt seem to work?
Error log:

I am getting a bunch of linker errors when trying to link to FastParse in a Scala project which I've just tried to build a ScalaJS web app in.
I added the ScalaJS dependency for FastParse into my build.sbt: here's approximately the relevant line (full file here):
libraryDependencies ++= Seq(
"com.lihaoyi" %%% "fastparse" % "0.4.1"
)
My errors are voluminous, but here's a representative one:

What am I doing wrong?
The problem was that I was requiring the JVM version of FastParse two lines up in my build.sbt. This broke my build apparently. I removed that line and cleaned my build and now both the ScalaJS and ScalaJVM versions of the project are building nicely.
(Thanks heaps to Li Haoyi for spotting the problem for me)
I'm having my apis in play 2.3 with reactive mongo. Recently, i tried to cleaned the project and during the process, some things got updated. Later, when i tried to run or compile that, i'm getting these errors. Apart from clean, i didn't do anything. Kindly help me.

Thanks,
Your version of Play is not compatible with the newest Snapshot of Play Reactive Mongo. You could just use Version 0.10.5.
Add this to your Library Dependencies
"org.reactivemongo" %% "play2-reactivemongo" % "0.10.5.0.akka23"
