The literal view is not connected, and then try to modify the proxy address (my company needs to use an agent to access the extranet), or failure.

It was later discovered that it was necessary to set up Grails's proxy line, as follows:

1. Setting commands

Grails add-proxy myproxy--host=<server>--port=<port>--username=<username>--password=< Password>grails set-proxy myproxy

2. Open ~/.grails/proxysettings.groovy, found the content as follows (WIN7 platform error, Mac platform Normal, you can notice):

myproxy=[' Http.proxyhost ': true, ' http.proxyport ': true, ' http.proxyuser ': ', ' http.proxypassword ': ', ' Http.nonproxyhosts ': ']

Currentproxy= ' myproxy '

Then manually modify the host and port, and then perform grails, successfully.
