If you use Eclipse, you'll be pleased to know that the repository contains an Eclipse project file. To get going, choose "Create a new project from existing sources." This should import all that is necessary into Eclipse.

Eclipse, Nutch, and the class path

You can end up in a mess with the class path, since ant has one way of managing the class path, whereas Eclipse has a second. So things that work in Eclipse can fail in the ant targets.

Setting up eclipse and DiscoverEd on a windows box

install eclipse Galileo EE select his package: Eclipse IDE for Java EE Developers (189 MB)

To install subversion module:

HELP-> Install new software -> "work with" = subclipse - select checkboxes for three groups of software, "Subclipse", "Subclipse Integrations", "Subclipse SVNKit Option" then click "Next", etc., accept certificate, and "Finish"

To install git:

egit is a relatively new addon to eclipse- It's in the incubation phase. "Help" -> "Install new software" add the site then select that site, it will be scanned for pluggin software, one package will be found, select it, and install it.

Getting started:

On June 23,2010 a new version of Eclipse, "Helios" will be released which includes many projects built in to it, including egit.

Since git is not working real well, or completely, with exlipse, you might want a native windows client and here is one that is a well known favorite (we're using the otrtoiseSVN and tortoiseCVS tools for years)
