Check the bottom section for suggestions to fixes. == Before you start == Setting up Nutch to run into Eclipse can be tricky, and most of the time you are much faster if you edit Nutch in Eclipse but run the scripts from the command line. However, it's very useful to be able to debug Nutch in Eclipse and is also extremely useful when applying and testing patches as it enables you to see them working in a larger context. This being said, you will still benefit greatly by looking at the hadoop.log output. @@ -32, +34 @@ Use the Subclipse plugin to check out the latest Nutch Trunk development. * File > New > Project > SVN > Checkout Projects from SVN - * Create new repository location > https://svn.apache.org/repos/asf/nutch/trunk + * Create new repository location > https://svn.apache.org/repos/asf/nutch/trunk + {{{ + Use https://svn.apache.org/repos/asf/nutch/branches/2.1/ for 2.1 version.
