Exclude generated source package directory in SBT project

I have an SBT project which uses the sbt-xjc plugin to create JAXB Java classes from the QTI XSD (this one in particular). My XSD has a dependency on MathML and it creates MathML classes as well as QTI ones as expected. The only xjc flags I am currently using are -verbose -extension.

Here's my directory tree:

- src/main/resources/imsqti_v2p1.xsd
- target
  - classes/org
    - imsglobal/... - Contains QTI .class files
    - w3_1998/math/mathml/... - Contains MathML .class files
  - src_managed/main/org
    - imsglobal/... - Contains generated QTI .java files
    - w3/_1998/math/mathml/... - Contains MathML .java files

However, I have another JAXB project with a dependency on MathML and that one also generates MathML classes. I want to get rid of the duplicate classes. I created a MathML JAXB project and added it as a dependency to the other 2 projects. How can I tell SBT to create a QTI autogen JAR which does not include the MathML classes?

I tried something similar to this answer, but it's not working. The MathML classes are still being included in the JAR. Here's my attempt that I added to my build.sbt:

val mathmlPath = "org/w3/_1998/math/mathml"
def isInPath(path: String, file: File) = file.getCanonicalPath.startsWith(mathmlPath)
(managedSources in Compile) := managedSources.value.filterNot(file => isInPath(mathmlPath,file))

I'll accept any of the below to get this to work:

  1. Configure sbt-xjc to not generate MathML classes.
  2. Configure sbt to not compile the MathML classes.
  3. Configure sbt to not package the MathML classes.

You use the mappings key to define the content of jar. See: http://www.scala-sbt.org/0.13/docs/Howto-Package.html

In your case, you can exclude MathML files (assume they all starts with org/w3_1998/math/mathml in jar) by the following settings in build.sbt:

mappings in (Compile, packageBin) ~= { _.filterNot {
  case (filePath, pathInJar) => pathInJar.startsWith("org/w3_1998/math/mathml")
}}

or less verbose (& less readable to some):

mappings in (Compile, packageBin) ~= { _.filterNot(_._2.startsWith("org/w3_1998/math/mathml")) }
