I'm using sbt 0.10 to build a Scala project using just a build.sbt file instead of a full configuration.
Every time I start sbt it gives me the messages as follows:
[info] Set current project to default-ee699e (in build file:/Users/.../project/plugins/)
[info] Set current project to default-8febe7 (in build file:/Users/.../)
I did set the name and mainClass settings in the build.sbt file, so I don't know what I need to set to get the project names default-XXXX go away.
EDIT: the answer given below is correct in that this is cosmetic. If you switch to a full configuration of sbt, then it uses that project's name as opposed to default-XXXX however.
