(Quick Reference) # 4.1.5 Configuring an HTTP proxy Version: 6.0.0 ## 4.1.5 Configuring an HTTP proxy To setup Grails to use an HTTP proxy there are two steps. Firstly you need to configure the `grails` CLI to be aware of the proxy if you wish to use it to create applications and so on. This can be done using the `GRAILS_OPTS` environment variable, for example on Unix systems:
    export GRAILS_OPTS="-Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3128 -Dhttp.proxyUser=test -Dhttp.proxyPassword=test"
| The default profile repository is resolved over HTTPS so `https.proxyPort` and `https.proxyUser` are used, however the username and password are specified with `http.proxyUser` and `http.proxyPassword`
For Windows systems the environment variable can be configured under `My Computer/Advanced/Environment Variables`. With this configuration in place the `grails` command can connect and authenticate via a proxy. Secondly, since Grails uses Gradle as the build system, you need to configure Gradle to authenticate via the proxy. For instructions on how to do this see the Gradle user guide section on the topic. | Quick Reference (hide)
