401 Unauthorized access for Github API using HttpBuilder (Groovy)

Question

I wrote a Groovy script to manage some organization repos on Github. It was working great until several weeks ago, when the same script started failing. Maybe Github changed some aspect of their API? Or maybe I'm doing something stupid. I've narrowed the problem down to this simplified example (requires a valid github account):

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.6' )

import groovyx.net.http.HTTPBuilder

String username = System.console().readLine 'Username: '
char[] password = System.console().readPassword 'Password: '

def github = new HTTPBuilder('https://api.github.com')
github.auth.basic username, password.toString()
def emails = github.get(path: '/user/emails', 
    headers: ['Accept': 'application/json', 'User-Agent': 'Apache HTTPClient'])
println emails

Output:

$ groovy GithubHttpBuilderTest.groovy
Username: username
Password:
Caught: groovyx.net.http.HttpResponseException: Unauthorized
groovyx.net.http.HttpResponseException: Unauthorized
at groovyx.net.http.HTTPBuilder.defaultFailureHandler(HTTPBuilder.java:652)
at groovyx.net.http.HTTPBuilder.doRequest(HTTPBuilder.java:508)
at groovyx.net.http.HTTPBuilder.get(HTTPBuilder.java:292)
at groovyx.net.http.HTTPBuilder.get(HTTPBuilder.java:262)
at groovyx.net.http.HTTPBuilder$get.call(Unknown Source)
at GithubHttpBuilderTest.run(GithubHttpBuilderTest.groovy:10)

Using the same credentials, curl works:

$ curl -u username https://api.github.com/user/emails

Output:

[
  "username@example.com"
]

Am I missing something on how to properly authenticate to the Github API using HttpBuilder?

EDIT: fixed an error in my code, where I treated System.console().readPassword as a String instead of its actual return type: char[]. Oops.

The github.auth.basic username, password doesn't seem to work, you need to set it manually:

String userPassBase64 = "$username:$password".toString().bytes.encodeBase64()    
def github = new HTTPBuilder('https://api.github.com')
def emails = github.get(path: '/user/emails', headers: ["Authorization": "Basic $userPassBase64"])
