I'm trying to follow this tutorial about scalatra deployment.
But I get error on > container:start, I very new to scala and have no idea what to do, googling result tells me to setup xsbt-web-plugin, but is it right? isn't examples need to fully independent for such custom dependencies or it is scala way?
upd(console output):

It looks like that README is messed up. Try this example instead:

And you can always follow this guide:

I'm trying to use mdoc in a simple SBT single-project build (link). mdoc requires me to create a subproject for the documentation, but I'd like to avoid moving all the code to a subfolder. I was trying to create a docs subproject that depends on the root project:
lazy val core = project.in(file("."))
lazy val docs = project.in(file("docs")).dependsOn(core)
However, this makes SBT try to find a JAR for my root project (obviously not finding it):
(sbt) core ❯ docs/compile

With other subproject deps (e.g. if I make the core project point to another folder) SBT adds a direct classpath dependency to the subproject's target/ folder. Why is the root project handled differently? Is there another way to make this work?
I tried to create a hello world following instructions given in the sbt-documentation.
$ sbt new sbt/scala-seed.g8

First, I am clueless why the build tool is using scala-2.10, when the generated build.sbt file has "scalaVersion" 2.12.1 specified under "inThisBuild" settings.
Second, and the main issue is, how to debug and fix the
UnknownFormatConversionException: Conversion = '0'
Not sure how to get past the "Hello, World!" example.
I am trying to follow code from below link
http://spark.apache.org/docs/latest/quick-start.html
But when I am trying to create package it is failing. I want to know 2 thinks
obviously, why it is failing
why it is showing older version of the scala, while I mentioned 2.11
Below is the error message.

when you run sbt package , sometimes it fails as there are no dependencies that are downloaded and will be resolved for the files imported.
Try running, sbt run first and then sbt package . sbt run should bring in all the dependencies on top of which packaging and compiling will be possible.
If the above does not solves your problem, you need to share your sbt build file and the environment that you are using. In which directory you are running these commands, will also play a role.
I created a new project using Typesafe Activator. In the command prompt I execute the command activator dependencies. This results in:

Versions used:

Analysis
First, dependencies is not valid sbt commands. (All sbt commands can be used also in activator.)
Solution
Either you mean libraryDependencies (which is an sbt setting) so call
activator libraryDependencies
Or you want to see the classpath of the dependencies ( a sbt task, so you need to use show to see the output of the sbt task), e.g.
activator "show dependencyClasspath"
Edit as of 2015-09-30,3:50am
If calling from console, the combined command must be put into quotes. Here: "show dependencyClasspath"
I'm having trouble with installing Apache Spark on Ubuntu 13.04. Im using spark-0.8.1-incubating, and both ./sbt/sbt update and ./sbt/sbt compile work fine. However, when I do a ./sbt/sbt assembly I get the following error:
[info] Set current project to default-289e76 (in build file:/node-insights/server/lib/spark-0.8.1-incubating/sbt/)
[error] Not a valid command: assembly
[error] Not a valid project ID: assembly
[error] Not a valid configuration: assembly
[error] Not a valid key: assembly
[error] assembly
[error]
I googled for stuff related to this but couldn't find anything useful. Any guidance would be much appreciated.
The current project set to default-289e76 message suggests that sbt was called from outside of the Spark sources directory:
$ /tmp ./spark-0.8.1-incubating/sbt/sbt assembly
[info] Loading global plugins from /Users/joshrosen/.dotfiles/.sbt/plugins/project

[error] Not a valid command: assembly

[error] Not a valid configuration: assembly

[error] ^
Running ./sbt/sbt assembly works fine from the spark-0.8.1-incubating directory (note the log output showing that the current project was set correctly):
$ spark-0.8.1-incubating sbt/sbt assembly
[info] Loading global plugins from /Users/joshrosen/.dotfiles/.sbt/plugins/project

You typed "abt" twice, but shouldn't that be "sbt"? Apache Spark has its own copy of sbt, so make sure you're running Spark's version to pick up the "assembly" plugin among other customizations.
To run the Spark installation of sbt, go to the Spark directory and run ./sbt/sbt assembly .
