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.

With scala 2.12.4 when I use theses parameters

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 have created a project by importing existing sources in Intellij IDEA.
When I run from my comand line,sbt and then console I got this

My example folder
milenko#milenko-desktop:~/example$ ls
assignment.sbt build.sbt project src target
Then I have changed directory to project,and run sbt and console in project.
My IDEA import is here
It seems that CommonBuild.scala is not positioned at the wright place.How to change this?
You should run sbt command from the root of your build, not in the project directory. project directory is used to build the build definition of your project, because sbt is recursive.
In other words, in your case you need to run sbt in ~/example directory.
I was wondering if I could get some help with this one. I know there are many different issues with the same title, however, after following all the instructions (I hope), I could not get it to compile still. I've been at this for over 7 hours.
This is my issue. I am using Cygwin64 terminal to do some scala programming with sbt. I run the test and make sure that the test file is in the test folder but nothing is working. I have tried to compile it without the test file and then bring it back in but it does not work either.
$ sbt test

Is there anything I can do?
I had the same problem. Running sbt test in the project root gave me the object scalatest is not a member of package org error. But when I changed to src/test directory, it completed successfully.
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"
I am trying to compile the scala breeze library (release 0.9) with sbt 2.13.

I am on java sdk 1.7.0_02
What should I do?

I answered this on Breeze's mailing list, but this is because you're using a non-HotSpot VM. I'll delete this class in the next release of Breeze.
