Gradle can't resolve dependencies through my http proxy

Question

when I try to run gradle dependencies on my computer I am getting a 407 status code "Proxy Authentication Required."

I created a gradle.properties file in my %GRADLE_HOME% directory. gradle.properties contains the following entries:

systemProp.proxySet='true'
systemProp.http.proxyHost=http-proxy.nwie.net
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=%myUserNameHere%
systemProp.http.proxyPassword=%myPasswordHere%

I can successfully get through my proxy for ruby gems by setting HTTP_PROXY to the following value: http://%myUserNameHere%:%myPasswordHere%@http-proxy.nwie.net:8080

I am using gradle-1.3, please let me know if there is something I am missing.

Thanks in advance!

UPDATE: I tried setting systemProp.http.proxyUser to a new value in domain/username format. Below are my current properties file contents:

systemProp.proxySet=true
systemProp.http.proxyHost=http-proxy.nwie.net
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=http-proxy.nwie.net/%USERNAME%
systemProp.http.proxyPassword=%PASSWORD%

I am currently getting the same error message I found initially.

Some dependencies are fetched from servers that run over HTTPS so you need to specify values for https properties as well:

systemProp.https.proxyHost=http-proxy.nwie.net
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=http-proxy.nwie.net/%USERNAME%
systemProp.https.proxyPassword=%PASSWORD%
