[m2] how to have two jars (api and impl) from one project

[Meg Hsu]

Hi all,
 My project has several sub-projects, each project has the following
structure:
 /module1/src/... /module1/api
 ... /module1/impl
 I need to have one jar for the api classes only, and the other of the impl
classes.
Any suggestions on how to do this on M2?
I was using the compiler-plugin's include/exclude, but then I have to have 2
pom.xml files.
 There are also tests that need to be ran for the project.
 Thanks.
