title: Gradle failing to download distribution behind company proxy
body: <p>Trying to get Jenkins behind my corp proxy to build my java library project and it keeps timing out during download of the distribution. I've followed many guides on trying to get gradle to utilize proxy settings in the <code>gradle.properties</code> file build it doesn't seem to work. I know the proxyHost and proxyPort is correct. Is there something that I'm overlooking or is it a different issue other than the proxy?</p>
