IntelliJ 13 not picking up build.sbt changes - scala

I'm using IntelliJ 13.1.2 on OS-X Mavericks.
I added a new dependency to my build.sbt inside an IntelliJ project. I synced my project as well as my build.sbt but I cannot import classes from this new library in my Scala classes.
However, when I do a sbt clean complile; sbt console on a terminal (outside of IntelliJ) I can successfully import classes from this new library.
Can anyone help me resolve this ?
Thanks

In preferences -> SBT (in Project Settings section) -> check the box next to 'Use auto-import' and that should keep IDEA synced with your build.sbt

sbt dependency root catalog differs from intellij libraries after import

I'm using Scala plugin version 1.3.3 for Intellij 14.0.3 at my work computer and have started a new SBT project from scratch without any hassle.
But my problems starts right here where build.sbt file have compile errors in Intellij, it can not resolve any line of code. I can how ever auto import by changing the build.sbt file and adding a library dependencies..
So I tested to add scalatest which is downloaded to an .ivy2 directory, but a totaly different one that Intellij are using.
This is how ever how my project structure are looking like, every libs have an error due to wrong path.
And here is where SBT plugin is locating all of it's dependencies and scala libs.
I know how to change where .ivy2 directory will be stored by adding these two parameters to
Settings -> Build,Execution, Deployment -> Build Tools -> SBT -> JVM Options -> VM parameters
-Dsbt.ivy.home=c:/.ivy2
-Dsbt.home=c:/.ivy2
But it only works for .iv2 folders and not the .sbt folders that are also in the wrong place. I believe that's the cause of why I can't resolve the symbols in the build.sbt script.
Does anyone know why this is happening and how I just can have one directory for both Scala plugin and Itellij project files?

sbteclipse not adding generated source folders to java build path?

I ran sbt eclipse on a Scala Project and when I imported it into Scala IDE(4.0.0 RC2), it gave me a type not found error as the types referred to were actually auto-generated code which were at target/scala-2_10/src_managed/main/compiled_avro/org/... I was able to do a sbt compile at the console though.
I got it to compile by adding the above folder to the Java Build Path.
My question is that since sbt eclipse can already detect Java Projects which the current project depends on and since sbt compile works at the console, should sbt eclipse be able to figure out dependencies to source folders of generated code as well? or maybe such a feature exists and I just don't know about it?
This may not be the correct way of doing things but to fix the issue i did the following.
sbt avro:compile
sbt compile
sbt eclipse
In eclipse i right clicked on target/scala-*/src_managed/main/compiled_avro > build path > use as source folder
The sbteclipse way:
Edit your project or global build.sbt file. My global ~/.sbt/0.13/build.sbt contains:
import com.typesafe.sbteclipse.plugin.EclipsePlugin._
EclipseKeys.createSrc := EclipseCreateSrc.Default + EclipseCreateSrc.Managed
I'm using an older version of _sbteclipse, version 2.5.0 (various non-relevant reasons), which seems to require both the import and a single blank link between each line of real content (this drives me a bit crazy, yes). I don't believe the import is required for newer versions of sbteclipse.
sbt clean avro:compile compile
sbt eclipse

Play with Activator Issue on IntelliJ Idea 14

I have the following problem on IntelliJ IDEA 14:
I created a Play (Scala) project using the Activator (v1.2.10). Then, I converted it to an IDEA project using activator idea command. When, I opened the project with IDEA 14 (Community Edition) the SBT module is not enabled. Therefore, a new dependency in build.sbt file is not included in the classpath. Moreover, the project is not listed in IDEA's SBT view.
The following warning is shown by IDEA:
"This IDEA project is converted from an SBT project by gen-idea tool, which currently relies on a legacy Scala project model. Please consider using built-in SBT support via the Import project action."
Note that, the Scala and SBT plugins are already installed on IDEA.
I don't encounter with the same issue in IDEA 13.
Have you tried File | Import Project and select build.sbt file?
IDEA imports it as an SBT project, with all the dependencies properly resolved. It works fine for me on IDEA 14 and on 13.
Apparently, this is a bug in some versions of IntelliJ 14, that just got fixed (as of version 14.0.3). Updating IJ then updating the scala plugin seems to make things work.
In this case simply import manually the "build.sbt" from your project, so if the directory is ~/Documents/myPlayApp then choose to import ~/Documents/myPlayApp/build.sbt

Intellij 13.1.3 import project from sbt not working

I have followed the instructions , attempting to either import from build.sbt or open project from build.sbt.
The end result is that the scala libraries are not imported as shown in the screenshot.
I have also tried sbt gen-idea from the command line.
This is just a problem that keeps surfacing..
If you are using Intellij, why don't you create scala sbt project? Then just add the libraries in the build.sbt and refresh the project or re-run the sbt gen-idea. The libraries will appear. See this link:
http://confluence.jetbrains.com/display/IntelliJIDEA/Getting+Started+with+SBT
I STILL have not figured out what the "magic" sequence of actions to follow in order to have a reliable sbt build.
This time around the following worked:
TWICE running
sbt gen-idea
and then import'ing the build.sbt as a new scala project
What did not work
Import project from build.sbt (without sbt gen-idea)
Open project from build.sbt (ditto)
Open build.sbt from Explorer (selecting IJ to open it)

Editing Build.scala in Intellij

I want to migrate our build from maven to SBT, so now I work separatedly on Build.scala file. However I don't benefit from any syntax highlighting (that is quite obvious, I don't have SBT in my classpath). What is the correct way to get SBT to my classpath, adding sbt-launch.jar does not seem to help.
IntelliJ 13 has built-in SBT support; if you're running a lower version, then you can have a look at their sbt plugin.
There's also an sbt plugin on github for generating idea project files. I've had success with running the gen-idea task it provides.
Run sbt gen-idea. It will create a "YOUR_PROJECT_NAME - build" project within your main project (for whatever your YOUR_PROJECT_NAME happens to be). Under the project folder of the build project, I was able to write a Build.scala with the following code:
import sbt._
object Build extends Build {
}
The SBT Build trait is recognized just fine. I'm running IntelliJ 13 build #IU-133-696, Scala plugin 0.30.378.
Eventually what I did is finished to write my build.sbt stub, and opened a project with it. Now everything seem to work.
