I’m having issues using Gradle through my proxy at work. It gets stuck in an infinite loop while downloading dependencies. I ran this exact same Gradle build at home (without the proxy) and it worked flawlessly.
The proxy I must go through requires no username or password. Here is the snippet from my gradle.properties file:
systemProp.http.proxyHost=internet.proxy.mycompany.com
systemProp.http.proxyPort=3128
systemProp.http.proxyUser=none
systemProp.http.proxyPassword=none
systemProp.http.nonProxyHosts=localhost
systemProp.https.proxyHost=internet.proxy.mycompany.com
systemProp.https.proxyPort=3128
systemProp.https.proxyUser=none
systemProp.https.proxyPassword=none
systemProp.https.nonProxyHosts=localhost
For some reason, I must set the proxyUser and proxyPassword as a dummy value: ‘none’. If I leave those properties out, or set them blank gradle will fail with:
Caused by: org.gradle.internal.resource.ResourceException: Unable to load Maven meta-data from http://repo.spring.io/snapshot/org/springframework/springloaded/1.2.1.BUILD-SNAPSHOT/maven-metadata.xml.
...
Caused by: org.gradle.api.UncheckedIOException: Could not GET 'http://repo.spring.io/snapshot/org/springframework/springloaded/1.2.1.BUILD-SNAPSHOT/maven-metadata.xml'. Received status code 407 from server: authenticationrequired
That might be a Gradle issue right there. Not sure. Anyway, if I leave the dummy properties for username or password in as I did above, Gradle becomes stuck in an infinite loop. Here is the debug snippet that will loop endlessly:

I’m stuck. Anyone know if there are any solutions to my problem? Thanks!
