Maven kinda works now. The build process is:
1. delombok code from src/main/java to target/generated-source/delombok
2. javac compiles from target/generated-source/delombok to target/classes (ie. without weaving)
3. aij compiles from target/generated-source/delombok to target/classes (ie. overwriting step 2)
4. delombok test code from src/test/java to target/generated-test-source/delombok
5. javac compiles from target/generated-test-source/delombok to target/classes (ie. without weaving)
6. aij FAILS to compile from target/generated-test-source/delombok to target/classes, but since I'm not using aspectJ in the test classes this might be ok...
Welp... it'll do for now.  At some point I'll need to make delombok work on test data (eg. delombok both src/main and src/test at the same time).  For now, so long as I don't use lombok in the test code, the testDelombok goal just copies my test code verbatim to be compiled (before throwing lots of errors at the console).
