Odd ... were these two builds started with different command lines?

The first one looks like it builds all subprojects:

[INFO] Reactor Build Order:
[INFO]
[INFO] PostgreSQL PL/Java
[INFO] PL/Java API
[INFO] PL/Java backend Java code
[INFO] PL/Java backend native code
[INFO] PL/Java Ant tasks
[INFO] PL/Java examples
[INFO] PL/Java packaging

The second one seems to skip right to pljava-so:

[INFO] Reactor Build Order:
[INFO]
[INFO] PL/Java backend native code
[INFO] PL/Java Ant tasks
[INFO] PL/Java examples
[INFO] PL/Java packaging


In nar-maven-plugin 3.2.3, the line with the null pointer exception
seems to be this one:

https://github.com/maven-nar/nar-maven-plugin/blob/nar-maven-plugin-3.2.3/src/main/java/com/github/maven_nar/Compiler.java#L499

which makes me think that some entry of 'defines' is a null.

If you're running the build with Java 14 or later, you may be able
to squeeze a little more information out of a NullPointerException
by putting the right -XX:... option in the MAVEN_OPTS environment
variable (see [1]). In this case it might only say something like
"cannot call method split() because receiver is null" (I don't see
a lot of other possibilities on that line) but in general it might
be helpful.
