"ant eclipse" not working for Apache Nutch repository

Question

I want to use Apache Nutch in Eclipse and I followed the steps from this site https://cwiki.apache.org/confluence/display/nutch/RunNutchInEclipse, but when I run ant eclipse, it always restarts with the following lines at the beginning:

$ ant eclipse
Buildfile: /.../nutch/build.xml
Trying to override old definition of task javac
  [taskdef] Could not load definitions from resource org/apache/rat/anttasks/antlib.xml. It could not be found.

clean-build:
   [delete] Deleting directory /.../nutch/build

clean-default-lib:

clean-test-lib:

clean-lib:

clean-dist:

clean-eclipse:

ivy-probe-antlib:

ivy-download:
  [taskdef] Could not load definitions from resource org/apache/rat/anttasks/antlib.xml. It could not be found.

I don't where the program should find the resource org/apache/rat/anttasks/antlib.xml because there is no org folder. Can you help me?

Answer 1

The warning about the missing "rat/anttasks/antlib.xml" can be ignored. It will disappear if the Apache Rat jar is installed by executing ant rat-sources is executed. This task is only required for source code maintenance (it verifies whether LICENSE headers are attached to all source files).

The target ant eclipse is executed once and write the Eclipse project files (.project and .classpath) which allow to import the Nutch source tree as Eclipse project.
