I am sitting in front of a Grails 3.1.4 Application. The build.gradle file looks like this:
buildscript {
...
}
version "01.01.12.99"
...
ext {
...
}
repositories {
...
}
dependencyManagement {
...
}
dependencies {
...
}
From one of my Service Classes I want to access the version variable. Is this somehow built in into Grails or am I trying to do something impossible? Are there ways to load this variable from a Service class?
I searched a bit and found this, but it accesses the Grails version not the project version.
Well, I recently started using Grails 3. Here I got the solution:
println System.properties.getProperty("info.app.version")
And you will get "01.01.12.99". This is working on Grails 3.1.8 for me.
Another way to achieve this (in addition to the solution provided by Shashank Agrawal) is relying on grailsApplication bean, with the following code:
grailsApplication.config.getProperty('info.app.version')
I tested this with Grails 3.1.9 and 3.2.7.

I'm trying to upgrade Grails 2.3.7 project to Grails 3.2.3. In 2.3.7, I used custom constraints and register them in /conf/Config.groovy using:
org.codehaus.groovy.grails.validation.ConstrainedProperty.registerNewConstraint('description', my.validation.DescriptionConstraint)
Then I can use something like this in domain:
static constraints = {
approvedDate(description: '>= applyDate')
}
However, in Grails 3.2.3, When I put above command (and remove org.codehaus.groovy from package name) in /conf/application.groovy I got following error:
Error occurred running Grails CLI: No signature of method: groovy.util.ConfigObject.registerNewConstraint() is applicable for argument types: (groovy.util.ConfigObject, groovy.util.ConfigObject) values: [[:], [DESCRIPTION_CONSTRAINT:[:]]]
I've notice that validation class is somewhat changed in Grails 3. However using constraint class from Grails-validation still got the same error.
All validation plugins I found were long abandoned before Grails 3. And I can't find any document for register new constraint in Grails 3.2.
Calling ConstrainedProperty.registerNewConstraint in /grails-app/init/BootStrap.groovy works. (tested with Grails 3.2.4)
class BootStrap {
def init = { servletContext ->
grails.validation.ConstrainedProperty.registerNewConstraint('description', my.validation.DescriptionConstraint)
// The rest of bootstrap code
}
}
Note. Previously, I call it from main() in /grails-app/init/Application.groovy. It works for running application. However, it does not work with integration test.
Another way you can create the runtime.groovy under config and register your constraints in the runtime.groovy as in grails 2.x.x:
org.codehaus.groovy.grails.validation.ConstrainedProperty.registerNewConstraint('description', my.validation.DescriptionConstraint)
I used grails 3.1.X in NetBeans 8.1.
Secured plugin is not resolving wen a used annotation. Code below:
package securityplugintest
//import grails.plugins.springsecurity.Secured
import grails.plugin.springsecurity.annotation.Secured //not esolved
#Secured(['ROLE_USER']) //not resolved
class ProductAnnouncementController {
def index() {
def announcements = ProductAnnouncement.createCriteria().list {
order("dateCreated", "desc")
maxResults(1)
}
render announcements.first()?.message
//render announcements.any()?.meassage
}
}
In NetBeans I have configured Grails 3.1.11, and spring-security plugin as
dependencies {
compile 'org.grails.plugins:spring-security-core:3.0.3'
}
I am following this manual and getting error for the last step.
Well First thing you should add plugin compile 'org.grails.plugins:spring-security-core:3.1.1 under the build.gradle .
I have just given you the different plugin version than that of you are using nothing more.
Second thing you should compile your project after adding the plugin.
This should do the trick for you.
But as you have stated that you are getting the red line under the import grails.plugin.springsecurity.annotation.Secured after above steps.
Please follow the below step :
As stated in the Grails 3 docs ->
To use annotations, specify securityConfigType="Annotation" , or
leave it unspecified because it’s the default:
Specifying securityConfigType as “Annotation”
grails.plugin.springsecurity.securityConfigType = "Annotation"
In your case please try to specify it.
And before running the app please clean -> compile -> run your app.
Can you please change your plugin to compile 'org.grails.plugins:spring-security-core:3.1.1' and compile it once added. – Prakash Thete
I have a project built with Gradle with 3 subprojects: trawler, adaptrice, frontage. Trawler is Groovy/Java, adaptrice is a Grails 3.1.7 app, frontage is a Grails 3 plugin used by adaptrice.
The top settings.gradle says include 'trawler', 'adaptrice', 'frontage', adaptrice/build.gradle contains,
grails {
plugins {
compile project(':frontage')
}
}
All this as per the Grails documentation. Everything works -- almost. The doWithSpring method in the plugin descriptor (class FrontageGrailsPlugin) looks like this,
Closure doWithSpring() { {->
entityPropGrabberFactory(EntityPropGrabberFactory) {
constraintsEvaluator = ref(ConstraintsEvaluator.BEAN_NAME)
proxyHandler = ref('proxyHandler')
}
}}
It is never executed when I do run-app for the adaptrice Grails app. There is a NPE when a supposedly injected bean is used. If I move the body of doWithSpring to the .../spring/resources.groovy of the adaptrice Grails app then it really works.
So my question is, what causes the doWithSpring in a Grails 3 plugin descriptor to be executed? Do I have to do something special when the plugin also is a subproject?
Forgive me for my English. Actually I want to use A template profiler plugin in grails 2.4.3. But it is unable to install in this grails version. It is available for the grails version 1.3.2. And I want to use it for grails 2.4.3. When I am trying to install. It shows an error
| Error Compilation error: startup failed:
C:\Project\target\work\plugins\profile-template-0.1\grails-app\services\profile\te

2 errors
Can anybody help me to get me out of this. Or You can suggest me another alternate option for this.
Thanks in advance.
If you have access to the source code of the plugin you could follow this:
In Grails 2 we no longer use ConfigurationHolder we use GrailsApplication.getConfig() instead. In the ProfileTemplateService add field GrailsApplication grailsApplication (Spring will inject it during app boot up) and change the:
ConfigurationHolder.config?.profile....
to
grailsApplication.config.profile...
Your service class should look like:
class ProfileTemplateService {
GrailsApplication grailsApplication
def method() {
a = grailsApplication.config.profile
}
}
Obviously there can more hoops to jump through before you actually make the plugin work.
How to install and use httpbuilder plugin in Grails?
Adding httpbuilder 0.5.1 to your application dependencies will cause errors. In particular, you'll get an error something like this:
java.lang.LinkageError: loader constraint violation: when resolving overridden method "org.apache.xerces.jaxp.SAXParserImpl.getParser()Lorg/xml/sax/Parser;" the class loader (instance of org/codehaus/groovy/grails/cli/support/GrailsRootLoader) of the current class, org/apache/xerces/jaxp/SAXParserImpl, and its superclass loader (instance of <bootloader>), have different Class objects for the type org/xml/sax/Parser used in the signature
I think the issue is that httpbuilder is exporting it's compile-time dependencies as runtime dependencies. An easy workaround is to declare the dependency like this in your BuildConfig.groovy:
grails.project.dependency.resolution = {
...
dependencies {
runtime('org.codehaus.groovy.modules.http-builder:http-builder:0.5.1') {
excludes 'xalan'
excludes 'xml-apis'
excludes 'groovy'
}
}
}
I think you need mavenRepo "http://repository.codehaus.org" in the repositories section as well.
There is the REST Client plugin:
Installation:
grails install-plugin rest
Example:
withHttp(uri: "http://www.google.com") {
def html = get(path : '/search', query : [q:'Groovy'])
assert html.HEAD.size() == 1
assert html.BODY.size() == 1
}
I ended up using the above step by ataylor but then commented out the block and tested plugin:
compile ":rest:0.7"
Rest plugin uses http-builder and without having the above dependancy my app still works fine and makes calls through http builder.
