Well, why should all resources needed to be packed? The built result may looks like: xxx-plugin `--- conf `--- web `--- xxx-plugin.jar `--- deps.jar `-- plugin.xml > Now, you may have tested your method and found that it does indeed work > - but the reason is a bit obscure: the bin/nutch and bin/hadoop scripts > add your build/ directory to the classpath, so that you can locally test > the latest versions of the code without creating the *.job file. > However, when you run your code on a Hadoop cluster your local build/ > directory is no longer accessible, and your method will mysteriously > fail - or even worse, you may get a different version of a resource from > an older version of the build/ directory found on Hadoop tasktracker > nodes ...
