Grails 3.0 and Spring Security Error - grails

Question

In my build.gradle I added this line of code
dependencies {
compile "org.grails.plugins:spring-security-core:3.0.3"
}
Then when I try to use it
import grails.plugin.springsecurity.annotation.Secured
#Secured('ROLE_ADMIN')
class SecureController {
def index() {
render 'Secure access only'
}
It "cannot resolve the symbol springsecurity"
I get the error
Error:(5, 1) Groovyc: unable to resolve class Secured , unable to find class for annotation
Any help would be much appreciated.

This is the whole build.gradle file

Answer 1

after 'apply plugin: "war"' add a line that says:
apply plugin: "maven"
in your repositories section, after "mavenLocal()" add a line that says:
mavenCentral()
this last recommendation is just cosmetic, but I would move your line:
compile "org.grails.plugins:spring-security-core:3.0.3"
and place it after the
compile "org.grails.plugins:scaffolding" line. it's good form to keep the initial set of grails dependencies pretty much as they are from the initial 'grails create-app' command. the exception to this rule is if you want to replace the logback logging with something else, but that's another story.
finally, you could also change your spring-security-core dependency to version 3.0.4 which is out now.

Spring security core has been updated the package location for #Secured Annotations. I use Grails 3.2.3 and Spring Security Core 3.1.1 int my project and works well. The following is the configuration the I used and is working as was in previos version of spring security core and Grails (2.X).
For installation, you have to add the entry in the dependencies block if your build.gradle file. Details in the oficial documentation for installation section for Spring Security Core
dependencies {
...
compile 'org.grails.plugins:spring-security-core:3.1.1'
...
To use the secured annotations in your controller, there were updates on the import (org.springframework.security.access.annotation.Secured) package and the #Secure annotation you have to assign to "value" the security statement you want to do. For example the annotation for #Secured('ROLE_ADMIN'), have to change like in the following example.
import org.springframework.security.access.annotation.Secured
#Secured(value=["hasRole('ROLE_ADMIN')"])
class SecureController {
def index() {
render 'Secure access only'
}
Detailed configuration are in the oficial documentation page, updates for secured annotation in version 3, and how to define secured annotations.

Answer 3

By importing
import grails.plugin.springsecurity.annotation.Secured
you will be able to resolve your problem.
It will again say that it cannot resolve symbol "Secured" but you need to ignore it because the code will run completely according to your expectation.
