I don't understand maven or grape, and I'm an idiot so give me the step by step if your answer is "go grap X-dependency manager and then rtfm and you're set." Where do i find and dump files to make this line work:
import groovyx.net.http.HTTPBuilder
It says Groovy: unable to resolve class groovyx.net.http.HTTPBuilder
Also I am unable to import groovyx.net.http.ContentType.URLENC It says unable to resolve class groovyx.net.http.ContentType.URLENC
Update:
apparently you can uncomment the line mavenRepo "http://repository.codehaus.org" in BuildConfig.groovy
