REST Client Grails Groovy unable to resolve class RestClientBuilder

I have an empty project created using GGTS, my app runs fine, I can see the views and navigate through them fine.

I need con call a REST api and consume the data provided, I read and added the necessary plug in to the BuildConfig file under the dependencies and then under the plugins section, none of them seem to work.

compile ":rest-client-builder:2.0.0"

I've created a controller, I'm not sure where to add the import here, so I've tried:

package myapp


class UserController {

    def index() {
        import grails.plugins.rest.client.RestBuilder
        String url = "https://foo.com/batch/$id"
        def resp = new RestBuilder().get(url) { header 'Authorization', 'Basic base64EncodedUsername&Password' }

        render resp
    }

but I get the error: unable to resolve class....

The API is returning JSON data, what I;ve done so far is just to create a new Grails project, add controller, add view and then the dependency.

I've cleaned an built the project several times but the error remains.

Thanks for your help.

I think that the problem is in your build.gradle dependency definition.

Insert the next line to your build.gradle file and I think that will be helpful:

compile "org.grails.plugins:rest-client-builder:2.1.1"

For more information follow the grails plugin documentation.

Please be aware that all the business logic should be placed in the service layer and not in the controller. It is a best practice to keep your controller lean as possible.

Another best practice is to define the following line:

String url = "https://foo.com/batch/$id"

in the beggining of the controller as static final String

static final String url = "https://foo.com/batch/"

and add the $id when needed in the code.

Here is how that should be called inside the method:

String url = "${url}/{$id}"

Import goes at the top

After the package line

And before the class line

Also, depending on your version of grails, you might want to move of ggts... Not sure it's supported any more...
