reStart — starts your application in a forked JVM. The optionally specified (JVM) arguments are appended to the ones configured via the reStartArgs/ reStart::javaOptions setting (see the “Configuration” section below). If the application is already running it is first stopped before being restarted.
reStop stops application. This is done by simply force-killing the forked JVM. Note, that this means that shutdown hooks are not run (see #20).
reStatus shows an informational message about the current running state of the application.
compile
Compiles the main sources (in the src/main/scala directory). test:compile compiles test sources (in the src/test/scala/ directory).
console
Starts the Scala interpreter with a classpath including the compiled sources, all jars in the lib directory, and managed libraries. To return to sbt, type :quit, Ctrl+D (Unix), or Ctrl+Z (Windows). Similarly, test:console starts the interpreter with the test classes and classpath.
package
Creates a jar file containing the files in src/main/resources and the classes compiled from src/main/scala. test:package creates a jar containing the files in src/test/resources and the class compiled from src/test/scala.
packageSrc
Creates a jar file containing all main source files and resources. The packaged paths are relative to src/main/scala and src/main/resources. Similarly, test:packageSrc operates on test source files and resources.
run<argument>
Runs the main class for the project in the same virtual machine as sbt. The main class is passed the arguments provided. Please see Running Project Code for details on the use of System.exit and multithreading (including GUIs) in code run by this action. test:run runs a main class in the test code.
runMain<main-class> <argument>
Runs the specified main class for the project in the same virtual machine as sbt. The main class is passed the arguments provided. Please see Running Project Code for details on the use of System.exit and multithreading (including GUIs) in code run by this action. test:runMain runs the specified main class in the test code.
