copying the launcher into the bin dir and creating the script

#!/bin/sh
java -Xmx256M -jar `dirname $0`/sbt-launcher.jar "$@"

works for me

Or on Windows:

set SCRIPT_DIR=%~dp0
java %SBT_OPTS% -Xmx256M -jar "%SCRIPT_DIR%sbt-launcher-0.4.6.jar" %*

SBT_OPTS allows one to configure a HTTP proxy which is needed for Ivy. For example: set SBT_OPTS=-Dhttp.proxyHost=172.22.100.15 -Dhttp.proxyPort=8080

I suggest this should be added to FAQ.

Thanks to both of you.

jzaugg: on unix, you can configure the proxy with the http.proxy environment variable and sbt will pick it up. Is http.proxy used in windows?

dmharrah, thanks for this nice simple, yet elegant tool. It is a proof that Scala can be used in a wide range situations, from a build script to a large application. It saves me lots of time in building Scala apps and learning Scala!

sbt does work with 1.5. It might be something with your setup, since people use Mac+1.5. You might try asking on the mailing list. It might have come up before.

Scala 2.7.7 should be added to the current list of supported Scala versions. Maybe a hint about 2.8 as well?

Thanks, Daniel. I've added 2.7.7. The best way to use 2.8 is really through sbt 0.6.x, but 0.6.x is still labeled experimental/in development. So, I'm not sure what I'd say there.

Thanks, Mark

I am playing with Scala 2.8 (I can't tolerate a language without default arguments and passing by name). I see that sbt seems to have 2.7.7 hardwired. Is there a simple way to make sbt use Scala 2.8? Thanks.

Russ P.

sbt is designed to work with multiple Scala versions. You can use 2.7.2 through 2.7.7 out of the box, for example. The problem with 2.8 is that it is not released yet and so any two revisions are likely to be binary incompatible.

The new iteration of sbt (0.6.x) was designed to work around this limitation. So, you might try using 0.6.8, the current version. It is labeled experimental, but my current priority is making it the next released version and some well-known projects are using it with success (as far as I can tell). You can find details in the mailing list archives or you can just go for the download from the downloads section.

Thanks, Mark

Mailing list: http://groups.google.com/group/simple-build-tool Downloads: http://code.google.com/p/simple-build-tool/downloads/list

I downloaded sbt 0.6.8. How do I tell it to use Scala 2.8? I've downloaded a nightly build of 2.8 a couple weeks ago. I see some instructions for using nightly builds, but they seem to apply to earlier versions of sbt. Are those the instructions I need to follow?

To switch the version being used for building:

  > set build.scala.versions 2.8.0.Beta1-RC5
  > reload 

To temporarily change to a version:

  > ++2.8.0.Beta1-RC5 

If you want to use a local Scala version, add the following to your project definition:

  override def localScala =
    defineScala("2.8.0-local", (scalaHome / "build" / "pack" ).asFile) :: Nil 

and reference it as 2.8.0-local.

It would be nice if some of the generated stuff could be grouped up and stored under a hidden directory in the root of the project. Similar to how git, mercurial, and maven hide all their cruft in hidden directory structures at the root.

I like SBT a lot, but the clutter is one thing I definitely do not like. It would also be nice if instead of using files in lib_managed if it could use files in .m2/repository ... or at least use them they were available.

Thank you fork all the work on SBT.

hi all i used the command java -Xmx512M -jar dirname $0/sbt-launch.jar "$@" but the file ~/bin/sbt not generated. why?

Some applications require stack size to be set greater than the default value i.e 512 Kb. The command I use is java -Xmx512M -Xss1024k -jar dirname $0/sbt-launch(version).jar "$@"

Proxy configuration error: You probably access the destination server through a proxy server that is not well configured

In case some files are downloaded and others are not, sbt might try to use both http and https. You will have to set both trough command line or environment variables.

Ex.

set SCRIPT_DIR=D:\Scala\sbt\
java -Dhttp.proxyHost=proxy_ip -Dhttp.proxyPort=8080 -Dhttps.proxyHost=proxy_ip -Dhttps.proxyPort=8080 -Xmx512M -jar "%SCRIPT_DIR%sbt-launch-0.7.4.jar" %*

hi everyone ! when i run ~/bin/sbt/sbt or sbt but failed which print: sbt: command not found

i put sbt-launch.jar and sbt file in ~/bin/sbt directory and my sbt file are:

 #!/bin/sh 
java -Xmx256M -Xss1024k -jar dirname $0/sbt-launcher.jar "$@"}}}
 what can i do

Since there is no mention of Cygwin here is the script used as 'bin/sbt':

dir=`dirname $0`
java -Xmx512M -jar `cygpath -w $dir`/sbt-launch-0.7.4.jar "$@"

Scala 2.8 is now released. How can I get sbt 0.7.4 to accept 2.8 as the scala version? Broken?

I have the same question. When I put in 2.8 or 2.8.0 for the scala version, sbt merrily goes and fetches scala 2.7.7.

Same question as above. How do I get sbt to use 2.8.0 instead of fetching 2.7.7?

same question here. i already have scala 2.8.0, how do i make the launcher use it?

I had problems with sbt under cygwin, even using pedrofurla's hint above. This post had the solution: http://blog.andrewbeacock.com/2009/10/how-to-get-scala-working-with-rxvt.html

So now this seems to work:

dir=dirname $0
java -Djline.terminal=jline.UnixTerminal -Xmx512M -jar cygpath -w $dir/sbt-launch.jar "$@"

Hello, thanks for this really nice tool!

The instructions are not very clear to the newcomers: it starts with "create a script to launch sbt" and if you don't go further you don't understand that it is explained below, and get stuck at that step.

Also the real jar is not named sbt-launch.jar but contains a version number. Maybe a separate page with precise instructions for newbies would be helpful?

specify 2.8.0 as the version and it will download it with maven2 no problem

Trying SBT (Simple Build Tool) for compiling a simple (one file, perhaps two) Scala application with some dependencies (Apache Pivot) on Windows as specifying all the jars on the command line quickly becomes annoying... (I try to convert the tutorial files to Scala).

Following the instructions here I have put the jar file in C:\Java\scala-2.8.0.final\misc and the sbt.cmd file in C:\Java\scala-2.8.0.final\bin Content of the latter:

@echo off
java -Xmx512M -jar C:\Java\scala-2.8.0.final\misc\sbt-launch-0.7.4.jar %*

As shown above, I use the current version, 0.7.4, supposed to support Scala 2.8. So far so good, when I type sbt on the command line, I get a prompt:

Project does not exist, create new project? (y/N/s)

Trying what is suggested, I answer s for a simple "hello world" setup (Quick Setup), perfect for my simple need (precisely a HelloScala? derived from the HelloJava? tutorial of Pivot). Gah! Apparently it starts to download Scala 2.7.7! Hey, I want 2.8, and I want the local version, no need to download yet another copy! And certainly not a copy per (micro-)project!

So I find the LocalScala page. Good, you have thought of this need. Bad, it is crypted... What is this ScalaInstance? object? Where to put it? "Override the localScala method to declare these local instances to sbt" Indeed, but where I am supposed to put the given code snippet?

Do I have to read the whole wiki before starting to experiment?

So I look at BuildConfiguration and have a hint: I have to create a .scala file in the project/build directory. Let's try it. First, let's make the project hierarchy:

> sbt
Project does not exist, create new project? (y/N/s) y
Name: Text
Organization: PhiLhoSoft
Version [1.0]:
Scala version [2.7.7]: 2.8.0
sbt version [0.7.4]:
Getting Scala 2.7.7 ...
^C^C^C^C^C^C
Terminer le programme de commandes (O/N) ?
^C

:-( At least I have project/boot and a build.properties file with these settings. OK, let's create project/build and put there Text.scala:

import sbt._

class ApachePivotTextTutorial(info: ProjectInfo) extends DefaultProject(info)
{
  lazy val hi = task { println("Apache Pivot Text Tutorial"); None }
  override def localScala =
    defineScala("2.8.0-local", new File("C:/Java/scala-2.8.0.final")) :: Nil
}

Let's modify project/boot/build.properties to change 2.8.0 to 2.8.0-local Trying again:

> sbt
Getting Scala 2.7.7 ...
^C^C^C^C^C^C
Terminer le programme de commandes (O/N) ?
^C

> sbt "++2.8.0-local"
Getting Scala 2.7.7 ...
^C^C^C^C^C^C
Terminer le programme de commandes (O/N) ?
^C

:-(( So I am stuck... Can you include some simple instructions for absolute beginners like me wanting to use their local install of Scala on small projects? Is there an option to create a project hierarchy without starting to download Scala?

As of the time of writing (October 2010), SBT uses Scala 2.7.7 for itself. It's alarming to specify (say) 2.8.1.RC4 and then see the message 'getting 2.7.7'. However, because SBT uses Ivy for dependency management, this will only happen once.

After SBT downloads its own version of Scala, then it will attend to yours. I'm hoping to get editor rights on the Wiki, as the documentation isn't as helpful as it could be.

Does the s in sbt really stand for simple? like the s in soap once stood for simple, until it became embarrassingly ironic.

Hello I'm new to the whole stuff and I'm trying to find my way through sbt. When I run sbt in my empty folder and tell it to use scala 2.8.1.final Iget:

F:\dev_scala\OltsLift?>sbt

I'm having a problem running SBT under ENSIME under Windows. it works great for me on my Mac.

http://sandbox.andyczerwonka.com/video/ensime_windows.swf

I think it's probably the way I setup my sbt.bat file. Has anyone else seen this behavior?

Alright.. I finally figured it out. Add this to your options when starting sbt (sbt.bat):

-Djline.terminal=jline.UnsupportedTerminal?

I've noticed than when working under Windows, putting simply "java" in sbt.bat file will ALWAYS trigger the recompilation of the sbt files. You must had the full path of your java.exe binary in order to prevent that.

So change the sbt.bat content with this (or adapt with your java.exe path):

set SCRIPT_DIR=%~dp0 
"C:\Program Files (x86)\java\jdk1.6.0_23\bin\java.exe" -Xmx512M -jar "%SCRIPT_DIR%sbt-launch.jar" %*

I'm running Window7 and the sbt.bat file just is not working for me. I created the sbt.bat file in the same directory as the sbt-launch.jar; Added the bat file to the PATH; however, when I go to a command prompt I get: {{{'sbt' is not recognized as an internal or external command, operable program or batch file.}}}

The sbt.bat file is: java -Xmx512M -jar "C:\tools\sbt\sbt-launch.jar" %*

If I type the line above into the command prompt it works.

PATH=....;C:\Program Files\Java\jdk1.6.0_18\bin;C:\tools\apache\apache-maven\bin;C:\tools\scala\bin;C:\tools\sbt\sbt.bat;

Any ideas?

slochmann,

Instead of the last part of your PATH being 'C:\tools\sbt\sbt.bat' I would recommend changing it to 'C:\tools\sbt\'

I'm not sure, but I don't think you should name executables directly in the PATH; you should only be naming the directories that they are found inside.

In cygwin, via rxvt, I found that the only way I could get it to work hassle-free was by using an alias, and the complete path of the jar file:

alias sbt='java -Xmx512m -Djline.terminal=jline.UnixTerminal -jar `cygpath -w /cygdrive/c/path/to/my/sbt-launch-0.7.5.jar`'

A better script for the launch

FILENAME=$0
if [ -h $FILENAME ]
  then
    FILE_NAME=`readlink $0`
fi
java -Xmx512M -jar `dirname $FILE_NAME`/sbt-launch-0.7.5.jar "$@"

so the sbt file can be placed on any path:

mkdir /opt/sbt
cd /opt/sbt
wget  http://simple-build-tool.googlecode.com/files/sbt-launch-0.7.5.jar

# create a file and add the script above 
vim sbt

chmod 755 sbt
ln -s /opt/sbt/sbt /usr/bin/sbt

ok thanks

When I run sbt reload, the file project/plugins/project/build.properties which is usually (always?) modified. The onlyy modification is the timestamp in the comment at the top of the file.

Should it be added to my .gitignore file?

I get an UNRESOLVED DEPENDENCIES error " :: org.scala-tools.sbt#sbt_2.8.1;0.7.7: not found "

Not sure what it means ?

for the people getting "unresolved dependancies"
