Grails not downloading plugins

Question

My grails 2.3.8 project is no longer downloading plugins. This has happened in the last few days.

I've set verbose output in BuildConfig.groovy

grails runApp

reports unresolved dependencies:

    module not found: org.grails.plugins#mail;1.0

If I download directly

http://grails.org/plugins/grails-mail/tags/RELEASE_1.0/grails-mail-1.0.zip

it downloads fine.

There is no proxy involved. I have also removed .grails and run the command again with the same result.

Answer 1

This is impacting only older versions of Grails that use the Ivy resolver. See https://stackoverflow.com/a/23594402/259167

Answer 2

This is a work around to your problem. If you can download the needed jar file manually, then download it and put it in the lib folder.
