Update: I found another one with a similar problem http://groups.google.com/group/play-framework/browse_thread/thread/c502be978a320cb7/28bc3a3253933aed?show_docid=28bc3a3253933aed
If I run Play and then try to do an eclipsify with sources Play says it can't find the files.
[todolist] $ eclipsify with-source=true [info] About to create Eclipse
project files for your project(s). [warn] [NOT FOUND ]
org.scala-lang#scala-library;2.9.1!scala-library.jar(src) (0ms)
Steps to reproduce.
Command: Play new test
Accept the name
Command: 1, Choose Create a simple Scala application
Command: cd test
Command: play
Command: eclipsify with-source=true
I will a have a working eclipse project and the referenced jar files.
However I won't have the source code compiled into the jars.
Try to do a play clean and execute the command again. If it still fails please raise a bug in lighthouse

When I try to create the ScalaTest example with this command:
sbt new scala/scalatest-example.g8 fails on TransportException
I get the following:
[info] Set current project to scala (in build file:/Users/chasrmartin/Dropbox/Etudes/Scala/)
[error] org.eclipse.jgit.api.errors.TransportException: git#github.com:scala/scalatest-example.g8.git: Auth fail
[error] at org.eclipse.jgit.api.FetchCommand.call(FetchCommand.java:139)
[error] at org.eclipse.jgit.api.CloneCommand.fetch(CloneCommand.java:193)
I've tried several workarounds from around the next (eg this SO question) to no avail. It would seem this has to be a simple problem, I got this command from a beginners tutorial.
Update
I got this command from https://www.scala-lang.org/documentation/getting-started-sbt-track/testing-scala-with-sbt-on-the-command-line.html
This project doesn't seems to exists anymore.
Instead I would prefer to run with the normal scala-seed.g8
> sbt new scala/scala-seed.g8
And add the test classes manually.
This is an equivalent tutorial with the same classes and tests.
The scala seed template already comes with the structure you want, with the test dependency. You can run sbt test normally.
So I need to download scala for one of my classes. I am using a mac pro and the command line to do so.
I downloaded sbt using homebrew which worked fine.
After these are the directions given:
Install the SBT plugin:
mkdir ~/.sbt
mkdir ~/.sbt/0.13
mkdir ~/.sbt/0.13/plugins
echo 'addSbtPlugin("edu.umass.cs" % "cmpsci220" % "3.0.0")' > ~/.sbt/0.13/plugins/plugins.sbt
To verify that everything is installed, I have to type 'sbt' to start SBT. Once typed, I should see output that looks like this:
[info] Loading global plugins from /Users/arjun/.sbt/0.13/plugins
[info] Updating {file:/Users/arjun/.sbt/0.13/plugins/}global-plugins...
[info] Resolving org.fusesource.jansi#jansi;1.4 ...
[info] downloading https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/edu.umass.cs/cmpsci/scala_2.10/sbt_0.13/3.0.0/jars/cmpsci.jar ...
[info] [SUCCESSFUL ] edu.cs#cmpsci;3.0.0!cmpsci.jar (1261ms)$
However, My issue is that once I type 'sbt' to verify things I get this line:
[info] Set current project to home (in build file:/Users/home/)
It asks me for a command. I have tried 'run', 'test', 'update'. They all run fine but it keeps asking me a command.
My goal is to get to the 'sbt console' so I can run scala, import packages, scripts, etc..
Any ideas on what the issue is?
You need to be in the folder of your SBT project to do sbt run.
First cd into it, then sbt run to run it (or sbt test or whatever :))
Type console at the sbt prompt.
Edit:
So actually, why do you think this is what you want? Are you trying to run scala code that you're given? Or are you trying to write scala code? If the latter, you should download intellij and the scala plugin.
Please make sure there is a scala file in the directory you run sbt.

I have a working Play Framework 2.1 application generated with typesafe activator that I've developed in Scala. I'm trying to deploy it in CloudBees using the instructions that can be found here: http://wiki.cloudbees.com/bin/view/RUN/Playframework#HDeployingaPlay2application using the method described under "Using Cloudbees SDK."
However, when I load up the play console and try to run the "dist" command, I get the error "Not a valid command: dist."
I've tried two run this three different ways:
In the terminal window (I'm using Mac OS X), I navigated to the project directory, ran the "activator" application (there is no application in that directory called "play", but "activator" seems to be the), then from the prompt that appears I enter the command "dist."
I downloaded the regular (non-activator) Play Framework distirbution file, add the directory to my path using "export PATH=$PATH:/Applications/play-2.2.2", navigated to the project directory, and ran the command "play dist."
Installed play using Homebrew. Navigated to the project directory and ran "play dist".
All three methods give me the same error (see below). Is the method different for my version of play? Am I missing something from the sbt file? How can I get this working?
Full output for "play dist":
Macmini-##########-#:nimrandslibrary.searchfu.esl kpyancey$ play dist

I think you have misconfigured something in your project.
To double check, generate a new project from Activator or try downloading https://github.com/CloudBees-community/play2-clickstart (which is correctly configured) and run play dist.
I'm new to Scala and Lift and SBT. I've cloned Ecommerce example from Lift's sample applications.
Now I want to simply run the application.
Documentation says, that container:start should start the app. But I'm getting error:
> container:start
[error] No action named 'container:start' exists.
[info] Execute 'help' for a list of commands or 'actions' for a list of available project actions and methods.
[info]
[info] Total time: 0 s, completed 25.05.2013 16:47:05
I guess that maybe it's because version difference.
[info] using LiftProject with sbt 0.7.5 and Scala 2.7.7
How can I start this application ?
And if it's caused by version difference is it possible to upgrade the application to latest sbt and scala version ?
Update
I've tried to use jetty-start and received another error:
> jetty-start
[error] No action named 'jetty-start' exists.
[info] Execute 'help' for a list of commands or 'actions' for a list of available project actions and methods.
I've also found another similar command jetty-run from sbt help. When I run it I'm getting a huge number of compilation errors. It seems like my scala 2.9.2 cannot compile the code.
This project, as far as I see, uses the old SBT version. The old way to start the web application is:
./sbt
> jetty-start
if you want to reload the app on source change, use ~ jetty-start
Note that there's a far more up to date liftweb project example here: https://github.com/lift/lift_25_sbt
probably sbt did not download the requried jar files.
run the following command
> sbt
> update
now sbt should download the requried jar files
>jetty-run
now sbt should compile and run the web-app.
I have used Scala for about a year and now want to get into Lift.
Following the official site, I got the guide at http://simply.liftweb.net/index-Chapter-2.html#toc-Chapter-2
However, the example does not work. Here is the error I get.
C:\Lift\hello>sbt update ~jetty-run
C:\Lift\hello>set SCRIPT_DIR=C:\scala\bin\
C:\Lift\hello>java -Xmx512M -jar "C:\scala\bin\sbt-launch.jar" update ~jetty-run
[info] Set current project to default-7944be (in build file:/C:/Lift/hello/)
[success] Total time: 0 s, completed 22 Feb, 2012 3:41:06 PM
[error] Not a valid command: jetty-run
[error] Not a valid project ID: jetty-run
[error] Not a valid configuration: jetty-run
[error] Not a valid key: jetty-run (similar: run)
[error] ~jetty-run
[error] ^
I have not used sbt before and prefer not to get sidetracked by having to learn sbt, maven or other stuff. I essentially want a "hello" world application (in this case, the chat application) to start up and running before I do any more digging into Lift.
It is unfortunate that the very first example in the official "getting started" guide is broken. Any ideas what the errors are. I tried the method suggested at http://groups.google.com/group/simple-build-tool/browse_thread/thread/60635edfadbcd816 without any luck
UPDATE
If what you want is just a "hello" world Lift application, I will suggest you download the official Lift 2.4 release here.
After you unzip that file, just cd scala_28\lift_blank or cd scala_29\lift_blank according to what Scala version you would like to use.
Then run sbt update ~jetty-run, this release included correct version and SBT start script for windows.
After this, you should able to browse http://localhost:8080 and get a single web page that has current date and time displayed, a typical Hello World program for web framework.
It seems you are using SBT 0.11 but Simply Lift is using SBT 0.7.x.
SBT has been made a lot of changes from 0.7.x to 0.11, there is no jetty-run command in 0.11.
You should download old SBT version if you just want it work and do not care using a old version SBT.
http://code.google.com/p/simple-build-tool/downloads/list
I think 0.7.7 will work.
It seems like you don't have ./ on your path. I believe all you need to do is go into the chat folder and use the command "./sbt update ~jetty-run" instead of "sbt update ~jetty-run".
It's and old question, but I haven't found that solution anywhere yet:
Seems like in lift 2.5 you should do container:start instead of ~jetty-run, so:
./sbt[enter]
update[enter]
container:start[enter]
My chat app was on http://0.0.0.0:8080
Install SBT 0.11+
Create a folder and follow instructions http://www.assembla.com/wiki/show/liftweb/Using_SBT
Copy src folder of https://github.com/lift/lift_24_sbt/tree/master/scala_29/lift_blank (or lift_basic) in your project folder
cd to your project folder and run sbt.
container:start will start server, container:stop to stop
OR use lifty
