JSBML qual extension

[jzw...@gmail.com]

Does the JSBML qual extension work in version 1.6.1?

I have the attached complete example using Gradle to compile and it gives the error:

"Error: qual package extension not enabled!"

In summary from the example... 

- I include the artifact using " implementation 'org.sbml.jsbml:jsbml:1.6.1'"

- I enable the package using setPackageRequired (I also tried enablePackage)

I've also tried explicitly including the jsbml-qual dependency.

No matter what I do I get `null` for the QualModelPlugin.

Thanks for any help,

Jason
