sbt has now completely moved to GitHub.

Project Console

Description

The console-project action starts the Scala interpreter with access to your project and to sbt. Specifically, the interpreter is started up with these commands already executed:

> val current: <YourProjectType> = <your project definition>
> import sbt._
> import Process._
> import current._
> 

This can be useful for creating and modifying your build in the same way that the Scala interpreter is normally used to explore writing code. Note that this gives you raw access to your build. Think about what you pass to FileUtilities.clean, for example.

Examples

Clean classes directory:

> FileUtilities.clean(mainCompilePath.asFile :: Nil, log)

Show current compile options:

> compileOptions.foreach(println)

Show additionally configured repositories. Then, show all repositories, including defaults.

> repositories.foreach(println)
> ivyRepositories.foreach(println)

Show the compile, test, and optional classpaths:

> compileClasspath
> testClasspath
> optionalClasspath

Run the console task to drop to another interactive prompt with your project (not the build) on the classpath:

> console.run

Run external processes:

> "tar -zcvf project-src.tar.gz src" !
> "find project -name *.jar" !
> "cat project/build.properties" #| "grep sbt.version" #> new File("sbt-version") !
> "grep -r null src" #|| "echo null-free" !
> new URL("http://databinder.net/dispatch/About") #> new File("About.html") !

Show the dependencies on external jars computed during compilation:

> compile.run
> mainDependencies.external
> mainDependencies.libraries
> mainDependencies.scalaJars

external consists of dependencies outside of the project, like the Java standard library. libraries are managed or unmanaged dependencies other than Scala libraries. scalaJars includes scala-library.jar and scala-compiler.jar if your project uses them.
