Grails unable to download dependencies behind proxy and firewall

grails

Solution

Generally it depends on the requirement of the application for dependencies. Ideally below items should resolve most of the dependencies (except if you want to refer some custom repo).

`//With reference to BuildConfig`

`grailsCentral()` - http://repo.grails.org/grails/core `grailsPugins()` - http://repo.grails.org/grails/plugins `mavenCentral()` - http://repo1.maven.org `artifactory` - http://repo.grails.org/grails

Additional repos are are also mentioned in `BuildConfig.groovy` as commented in newly created projects. (check their validity)

    // uncomment these (or add new ones) to enable 
    //remote dependency resolution from public Maven repositories
    //mavenRepo "http://snapshots.repository.codehaus.org"
    //mavenRepo "http://repository.codehaus.org"
    //mavenRepo "http://download.java.net/maven/2/"
    //mavenRepo "http://repository.jboss.com/maven2/"

Also, make sure if you have `inherits true` mentioned in the `repositories{..}` inside `BuildConfig`, the application inherits the repository definition from plugin. You need to make sure that is not blocked.

Inference It totally depends on the nature of the application and the type of dependencies it needs to work as expected. Being said that, for a basic web application I think the above mentioned repository locations should suffice the purpose at enterprise level taking into consideration that company wide repositories like Nexus are is use as well.

Problem

Title says it, Grails is unable to download dependencies behind my organization's proxy and firewall. Now that I know what the problem is I need to tell my IT department to allow requests to those URLs through the firewall. Based on the error messages Grails gave me I can determine that variants of... http://grails.org http://repo1.maven.org ...need to be let through the firewall, but I'm not sure if those two will get Grails everything it needs now, or in the future as I install plugins. What are all the domains/URLs Grails requests dependencies from? Update: I gave the list of the domains @dmahapatro provided to my IT department and it seems Grails is now able to resolve dependencies correctly. Here is a consolidated list of those domains: http://grails.org http://repo1.maven.org http://repo.grails.org http://snapshots.repository.codehaus.org http://repository.codehaus.org http://download.java.net http://repository.jboss.com
