Unable to tunnel through proxy when running Gradle Wrapper in Teamcity

Question

I'm running my gradle build in Teamcity behind a proxy, and facing an issue with the Gradle Wrapper being unable to download the Gradle zip file.

I've added the proxy settings to the Gradle command via gradle parameters.

/export/home/**/teamcity/work/1ea348ab17354b2f/gradlew --init-script /export/home/**/teamcity/plugins/gradle-runner/scripts/init.gradle -Djdk.http.auth.tunneling.disabledSchemes=”” -Djdk.http.auth.proxying.disabledSchemes=”” -Dhttp.proxyHost=***.com -Dhttp.proxyPort=3128 -Dhttp.proxyUser=** -Dhttp.proxyPassword=** -Dorg.gradle.daemon=false -d -b build.gradle bootRepackage

Here's the Exception I get :

I have also tried the following variations of setting the proxy :

-Dhttps.proxyHost=
-Dhttps.proxyPort=
-Dhttps.proxyUser=
-Dhttps.proxyPassword=

-DsystemProp.http.proxyHost=
-DsystemProp.http.proxyPort=
-DsystemProp.http.proxyUser=
-DsystemProp.http.proxyPassword=

-DsystemProp.https.proxyHost=
-DsystemProp.https.proxyPort=
-DsystemProp.https.proxyUser=
-DsystemProp.https.proxyPassword=

And have tried disabling tunneling for Basic Authentication as here :

-Djdk.http.auth.tunneling.disabledSchemes=””
-Djdk.http.auth.proxying.disabledSchemes=””

None of these options have seemed to work in Teamcity. Is there anything else I should be doing ?

Thanks much for your help.

As it turns out, the host/agent on which teamcity was running the build, wasnt connecting to the internet. Another agent which was, was able to download the gradle installation just fine, and run through the complete build.
