Dear nutch-users,
I am trying to make some changes to the Nutch's PruneIndexTool, but
before I start making those changes I wanted to make sure that I am able
to compile the current PruneIndexTool from the command line.
I checked to make sure that the java compiler works in general by using
it to compile a simple hello world program.
I did this by calling the following command from my nutch directory:
$ javac helloworld.java
//compiles with no errors
$ java helloworld
hello world
$
This led me to believe that the compiler is working.
After I determined that the compiler was working correctly, I then tried
to compile the PruneIndexTool.java file by calling:
$ javac PruneIndexTool.java
However, this command resulted in approx. 100 errors, which I have
listed at the end of this e-mail.
I think that problem might be the CLASSPATH variable in my .bash_profile.
My CLASSPATH is currently set to:
CLASSPATH=/home/jon/nutch-0.8.1/jakarta-oro-2.0.8
/src/java:/home/jon/nutch-0.8.1/lucene-2.0.0/src/java:/home/jon/nutch-0.8.1/src/java:/home/jon/nutch-0.8.1/src/plugin/urlfilter-regex/src/java:.
Here is the list of errors I am currently receiving. Any help you can
provide is much appreciated.
thank you,
....
