Well, it's a qualified success. After running maven, I couldn't find any
pljava.so or pljava.jar files anywhere, so I went into various subdirectories
and ran ant manually, which created some files named similarly to what I was
looking for. I put them manually into the PostgreSQL $libdir, because I liked
that method better than fiddling with dynamic_library_path, and after changing
LD_LIBRARY_PATH so postgres could find libjvm.so, was able to create the
language successfully.

Now I'm loading the examples, and get this:

pljava=# select
sqlj.install_jar('file:///home/josh/devel/pljava-build/pljava-examples/target/pljava-examples-0.0.1-SNAPSHOT.jar',
'samples', true);
WARNING: java.lang.NoClassDefFoundError:
org/postgresql/pljava/internal/Backend
ERROR: Unable to load class org/postgresql/pljava/internal/Backend using
CLASSPATH
'-Djava.class.path=target/lib//pljava.jar:/etc/alternatives/java_sdk/lib/management-agent.jar:/etc/alternatives/java_sdk/lib/tools.jar'

I'll see if I can figure out how to make that target/lib/pljava.jar classpath
absolute, and ... something meaninful. I expected maven to create nicely
packaged .so and .jar files for me, and it didn't, which suggests I'm doing
something else wrong.
