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.

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 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 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?
I get repetitive method name/Signature compilation failure when i try to use i18nFields in my domain class to support multiple languages.
Grails Version : 2.3.7 ( I tried with 2.3.4 and got the same issue and upgraded)
Documentation from Grails followed for this was http://grails.org/plugin/i18n-fields
My Domain class looks like
package com.sampleapp.domain
import i18nfields.I18nFields;
#I18nFields
class Products {
def name
static constraints = {}
static i18nFields = ['name']
}
My Config.groovy has the below line included to specify the locale
// internationalization support - testing
i18nFields {
locales = ['en','es']
}
BuildConfig.groovy plugin definition
plugins {
// plugins for the build system only
build ":tomcat:7.0.47"
// plugins for the compile step
compile ":scaffolding:2.0.1"
compile ':cache:1.1.1'
// plugins needed at runtime but not for compilation
runtime ":hibernate:3.6.10.6" // or":hibernate4:4.1.11"//
runtime ":database-migration:1.3.8"
runtime ":jquery:1.10.2.2"
// compile ":jquery-ui:1.10.2.2"
runtime ":resources:1.2.1"
// Uncomment these (or add new ones) to enable additional resources capabilities
runtime ":zipped-resources:1.0.1"
runtime ":cached-resources:1.1"
//runtime ":yui-minify-resources:0.1.5"
compile ':platform-core:1.0.RC6'
compile ":cache-headers:1.1.5"
runtime ':spring-security-core:2.0-RC2'
// internationalization
compile ":i18n-fields:0.8.1"
}
The compilation error is
grails-workspace\Test\grails-app\domain\com\sampleapp\domain\Products.groovy: -1: Repetitive method name/signature for method 'void setName_es(java.lang.String)' in class 'com.sampleapp.domain.Products'.
# line -1, column -1.
The Error is repeated for the name property for both en and es locales twice.
There is no error if i remove the i18nFields annotation and the sample app worked fine before this. I verified GGTS repetitive method name/signature error in controllers post for similar error in controller. I have also verified to ensure that groovy version is correct and in my case it is 2.1
Can somebody please give me any pointers on where i should look to resolve this issue.
This problem shows up when you are trying to use Java > v7 with any version of Grails < 2.3.7. Either downgrade your jvm or upgrade your grails.
Thanks for trying (and for making me know via github ;) )
The issue was known but hadn't been tackled yet.
The previous answer (commenting out methods) is not exact, event though it follows the right track, because the problem comes from new changes in Grails that will cause a collision in getters and setters.
The solution I've found is to separately create the property and the getter/setter, and it seems to work.
I'm releasing a new version as soon as it can be fully tested in a project, but code is already available in https://github.com/jorgeuriarte/grails-i18n-fields-plugin/tree/redis_integration (version 0.9-redis-SNAPSHOT) in case you want to use it.
Probably it has something to do with the new Binding mechanism in grails 2.3. Maybe the getters and setters are set automatic now?
When I comment out these two lines in ClassI18nalizator.groovy the error disappears. It seems to work at least partly. I can use the fields in scaffolding. It's not a real solution but maybe a hint for someone who understands grails better than me.
private def getSetterMethod(field) {
// setter should return void. that's why the return statement.
//return new AstBuilder().buildFromString("i18nfields.I18nFieldsHelper.setValue(this, '${field}', value); return;").pop();
}
private def getGetterMethod(field) {
//new AstBuilder().buildFromString("i18nfields.I18nFieldsHelper.getValueOrDefault(this, '${field[0..-7]}', '${field[-5..-1]}')").pop();
}
After that I run into a second issue:
No signature of method: groovy.util.ConfigObject.contain() is
applicable for argument types: (java.lang.String) values: [en_US]
I solved it by adding redisLocale to Config.groovy
i18nFields {
locales = ['de_DE', 'en_US']
defaultLocale = "en_US"
redisLocales = ['de_DE', 'en_US']
}
I'm using Grails and want to use groovyws to call an web-service.
But my groovyws.jar (0.5.2) have MANY dependences that I can't solve.
Is there any jar with all dependences included?
Note: I tried put in BuildConfig.groovy, this
dependencies {
'org.codehaus.groovy.modules:groovyws:0.5.2'
}
but I'm getting error:
Error executing script Compile: 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 ), have different Class
objects for the type org/xml/sax/Parser used in the signature
You can manually exclude xerces by:
dependencies {
runtime('org.codehaus.groovy.modules:groovyws:0.5.2') {
exclude: 'xerces'
}
}
GroovyWS pulls inn CXF, which again pulls in a lot of dependencies, some of them conflicting with classes already present in Java 6. You need to exclude all these dependencies if using Java 6, to avoid errors like the one you mention.
Here's my exclude list:
compile("org.codehaus.groovy.modules:groovyws:0.5.2") {
excludes 'geronimo-servlet_2.5_spec', 'servlet-api', 'jaxb-xjc', 'jaxb-impl', 'xml-apis', 'saaj-impl', 'junit', 'slf4j-jdk14', 'xmlParserAPIs', 'jaxb-api', 'saaj-api', 'xmlbeans', 'jaxen', 'geronimo-stax-api_1.0_spec', 'geronimo-activation_1.0.2_spec', 'abdera-client', 'geronimo-activation_1.1_spec'
}
Note that on Ubuntu you need jaxb-xjc and jaxb-impl after all, don't know why.
I found:
http://docs.codehaus.org/dosearchsite.action?queryString=groovyws+standalone
Tks a lot!
(search for "groovyws standalone")
Note: I saw this tip here.
