Subject: Schemagen NullPointerException
Hello,
I'm having some issues with the schemagen of the maven plugin. The error
says it's a NullPointerException and gives instructions on how to find out
more information about the error. So I follow the instructions to cd to the
directory and run a command to see the full -error. Which I run and the
results of that are "error: package javax.persistence does not exist" and
so on. Which seems like it's not finding the compiled classes at all. It
compiles and runs just fine with the schemagen part removed.
Any help would be appreciated, I'm processing a single class that links to
a few other classes. I also can produce xml based on the class just fine.
Maven 3.6
jaxb2-maven-plugin 2.4
JDK 1.8.0_192
