I am trying to modify the java CC rules in NutchAnalysis.jj.
As a preparation, I ran javacc (ver 3.2) to "compile"
NutchAnalysis.jj of Nutch 0.8 but the generated
Java files are little bit different than those
found in the src/java directory. Am I supposed to use
some javacc command line options?
BTW, shouldn't build.xml have rules that can build
the .java files from the .jj file, to be complete?
Below are the diffs:
