Question

I am facing same error every time m trying to install uploadr plugin through "grails install-plugin uploadr" command , i have mapped compile ":uploadr:0.8.2" in the BuildConfig.groovy but then also getting this

error.![error][1]
| Error Resolve error obtaining dependencies: Failed to read artifact descriptor for org.grails.plugins:uploadr:zip:0.8.2 (Use --stacktrace to see the full trace)
| Error Failed to read artifact descriptor for org.grails.plugins:uploadr:zip:0.8.2

The stacktrace output looks something like that:-

Answer 1

You are working behind a HTTP proxy and Grails cannot access the internet. You need to

grails add-proxy My-Proxy --host=proxy-server --port=4300  // according to [this][1]   

and then activate the proxy configuration by

grails set-proxy My-Proxy
