Compiling plugins for Nutch
Hi, I am currently trying to compile a plugin for nutch 2.3. Unfortunately
the ant task fails when trying to compile the plugin with the following
error
BUILD FAILED
/home/nutchStack/nutch/apache-nutch-2.3/src/plugin/simpleIndexFilter/build.xml:3:
The following error occurred while executing this line:
/home/nutchStack/nutch/apache-nutch-2.3/src/plugin/build-plugin.xml:46:
Could not create task or type of type: antlib:org.apache.ivy.ant:settings.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'antlib:org.apache.ivy.ant:settings'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries
implementing the functionality were not found at the time you
yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
task and make sure it contains more than merely a META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the needed
libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
- You are attempting to use a task defined using
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
I tried to compile other plugins within the src directory but I get the
same error. Could you advise please (new to ant and ivy)
Thanks.
Kind regards,

How are you building/compiling the plugin? which command are you executing and in which directory?

Re: Help. Nutch not crawling site.

What is your config? What happens when you run the crawl? What is in your
crawldb? What are your seed urls? What is the output of parsechecker on
that sight? If you can throw some info our way I'm sure we can help you
figure out why you're having problems.

Is there any reason why Nutch would not crawl this site ?
http://www.bitfixer.com
I have checked and can not find a robots.txt file.
Cheers
