I hope I am sending this to the correct list :)

I just saw this issue when I was trying to run indexchecker in local mode.

I solved this by changing this line in the ivy.xml
<dependency org="org.slf4j" name="slf4j-log4j12" rev="1.6.1" conf="*->master" />

to

<dependency org="org.slf4j" name="slf4j-log4j12" rev="1.5.5" conf="*->master" />

the pom.xml has the "correct" version but ivy.xml seems to be overriding it. (if that was an obvious statement, I apologize, but I am new to ivy and the whole Maven stuff)

this would be also helpfull:
http://www.slf4j.org/faq.html#IllegalAccessError


and for the record this is the error I got
kaveh@index9:~/build/nutch/runtime/local$ bin/nutch indexchecker
Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory
