[jira] [Updated] (NUTCH-1091) Remove commons logging dependency
from Nutch branch and trunk
[ https://issues.apache.org/jira/browse/NUTCH-1091?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lewis John McGibbney updated NUTCH-1091:
----------------------------------------
Affects Version/s: 2.0
Fix Version/s: 2.0
Summary: Remove commons logging dependency from Nutch branch and trunk (was: Remove commons logging dependency from Nutch branch.)
Initially I thought that this just applied to branch-1.4, however I also noticed that the commons-logging-1.1.1.jar still exists in $NUTCH_TRUNK/runtime/local/lib. Upon further inspection within ivy/ivy.xml there is no explicit reference to a common-logging dependency therefore it must exist as a dependency to some Nutch dependency with a default configuration.
{code}
<dependency org="commons-codec" name="commons-codec" rev="1.3"
conf="*->default" />
{code}
Unless we can determine and prove that common-logging is not required within any other Nutch dependency then ultimately we will be affecting some functionality which might/could have a detrimental impact.
On the other hand, if we found that there was no harm caused by removing the common-logging dependency completely by adding an exclude e.g.:
{code}
<exclude org="commons-logging-..." name="etc" />
{code}
or an even more explicit global exclusion, then we could completely diverge from the dependency altogether.
I will work on this and hopefully get some results shortly.

Sorry, I don't have my Apache login credentials handy, so replying
before I forget:
Use the slf4j-jcl:
http://mvnrepository.com/artifact/org.slf4j/slf4j-jcl/1.6.1
This is the commons-logging API forwarded to slf4j, so everything
should end up with whatever backend you choose to use. We do this use
logback as our backend, and ended up having to put in the slf4j
adaptors for commons-logging, JDK, and log4j into our dependencies,
and it works just fine.
