Nightly Builds

Nightly builds are currently being published to http://repo.typesafe.com/typesafe/ivy-snapshots/.

To use a nightly build, follow the instructions for normal Setup, except:

1. Download the launcher jar from one of the subdirectories of sbt-launch. They should be listed in chronological order, so the most recent one will be last.
2. Call your script something like sbt-nightly to retain access to a stable sbt launcher.
3. The version number is the name of the subdirectory and is of the form 0.13.x-yyyyMMdd-HHmmss. Use this in a build.properties file.

Related to the third point, remember that an sbt.version setting in <build-base>/project/build.properties determines the version of sbt to use in a project. If it is not present, the default version associated with the launcher is used. This means that you must set sbt.version=yyyyMMdd-HHmmss in an existing <build-base>/project/build.properties. You can verify the right version of sbt is being used to build a project by running sbt-version.

To reduce problems, it is recommended to not use a launcher jar for one nightly version to launch a different nightly version of sbt.
