Hi,
In Nutch we have a copy of Tika-core. But with just that lib we also have
access to the Tika.parser API from the other module. How does this all work
because i have had confusing results in the past (and now).
Right now we've added a class to org.apache.tika.parser.html but we get a
ClassNotFound with a newly compiled Tika. Our code compiles when we add tika-
parsers to the classpath, but when we run we get some obscure exception:
Exception in thread "main" java.lang.NoClassDefFoundError: Could not

When we previously patched Tika in the core module all went perfectly well but
patching the parser module and getting it all compiled in tike-core.jar seems
tricky. Any advice? What am i missing? How do the parser libs end up in the
core jar?
Thanks
