In one of my sub-projects, I have three sourceSets: a, b, main. When I execute :subproject:jar, however, I only get the "main" bit archived into the jar: neither the a or b sourceSets make it in. I've got *.class files in ./build/classes/a and ./build/classes/b - they just don't make it.
Any idea why that might be, or how I might work around it? ~~ Robert.
