1. Specify proxy settings in you gradle.properties file in your project:
# for http systemProp.http.proxyPort=80 systemProp.http.nonProxyHosts=*.cat.com|localhost systemProp.http.proxyHost=proxy.ap.cat.com # for https systemProp.https.proxyHost=proxy.ap.cat.com systemProp.https.proxyPort=80 systemProp.https.nonProxyHosts=*.cat.com|localhost
2. Copy these settings to (create if necessary) a gradle.properties file in your USER_HOME/.gradle directory
3. In Jenkins navigate to Manage Jenkins > Configure System. Under Global properties check Environment variables and fill in the following for name and value:
name: GRADLE_OPTS value: -Dgradle.user.home=/home/tomcat/.gradle -Dhttp.proxyHost=[proxy] -Dhttp.proxyPort=[proxy_port]
Where [proxy] is the proxy url and [proxy_port] is the port for that proxy. Add https options if required.
