From Eclipsepedia

To get started using this code, I'd suggest extracting everything from CVS and having a look at the examples provided:

cvs -d :pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse -q checkout -r releng_test \
-d org.eclipse.build.tools org.eclipse.releng.basebuilder/plugins/org.eclipse.build.tools

If using Eclipse, follow these steps:

Hit CTRL-N to open the New... wizard, then select CVS > Projects From CVS. Create a new repository if required, matching these details:

Host: dev.eclipse.org
Repository path: /cvsroot/eclipse
User: anonymous (no password)
Connection type: pserver (default port)

Browse to org.eclipse.releng.basebuilder/plugins/org.eclipse.build.tools.

Select the releng_test branch, not HEAD, to get the latest implementation code.
