Does cpd4sbt support multi project builds?
Currently not really, no. - Though it should be relatively straightforward to add this, I hope. I'll look into it when I get the time.
This would be nice addition.
@jmhofer Currently I can't use cpd4sbt with my multi project build, I can pull request, Do you have guidance for adding support in multi project builds?
I think the relevant setting is cpdSourceDirectories in Compile, which simply defaults to unmanagedSourceDirectories in Compile.
My first idea for an approach of multi-project builds probably would be to collect all the sub project source directories for this setting instead. We'd need to find out how to do that in sbt.
However, if you want to configure cpd for each sub-project separately, this approach might be too simplistic.
