Hi, I was able to add another source root pattern through the source subsystem but I'm now experimenting in a different direction: given the following project structure

module/src/scala/org/module/Stuff.scala

module/BUILD

If I add a

scala_library

with

sources=globs('src/scala/org/module/*.scala')

then

./pants export module::

will give me:

"root": [{ "package_prefix": "src.scala.org.module" }]

. Obviously I'd like to have only

org.module

as the package prefix. I've seen the

source_roots

option which takes a map but I don't understand the syntax, the default says:

{ '3rdparty/go':'(u'go_remote',)' ...

. What is this

'(u'

thing? Also, can I have both the root pattern option and the roots option?
