I installed HTTPbuilder using grape,

    D:\Documents and Settings\Administrator>grape install org.codehaus.groovy.module
s.http-builder http-builder 0.5.0
:: loading settings :: url = jar:file:/D:/Program%20Files/Groovy/Groovy-1.7.4/li
b/ivy-2.2.0-rc1.jar!/org/apache/ivy/core/settings/ivysettings.xml
:: resolving dependencies :: caller#all-caller;working
        confs: [default]
        found org.codehaus.groovy.modules.http-builder#http-builder;0.5.0 in cod
