I'm using grails 3.3.0 with rest api and gson views. I have the following setup...
Domain Class
package foo
#Resource(uri="/api/bars", readOnly = false, formats = ['json', 'xml'])
class Bar{
String firstName
String lastName
}
Controller:
package foo
class BarController extends RestfulController<Building>{
def show(){
respond Bar.get(params.id)
}
}
_bar.gson:
import foo.Bar;
model {
Bar bar
}
json {
name bar.firstName
}
_show.gson:
import foo.Bar;
model {
Bar bar
}
json g.render(template:"bar", model:[bar:bar])
directory layout:
/grails-app/views/
-----------------bar/
--------------------_bar.gson
--------------------_show.gson
This fails during build, test, compile and war with the following error:
Execution failed for task ':compileGsonViews'.
foo_bar_show_gson: 3: unable to resolve class foo.Bar
I followed the documentation but I cannot get around this. Please help!
I have the same issue, my problem got solved when I change the views-gradle version to the 1.2.7
classpath "org.grails.plugins:views-gradle:1.2.7"
After looking through github issues this seems to be caused by the rest profile and running on a Windows machine. If I start a new project using the web profile everything works fine.

I am writing an application with Xamarin.Android with MvvmCross. I want my Activity to inherit from MvxAppCompatActivity so that I can use fragments. Here is my base class:
public class BaseActivity<TViewModel> : MvxAppCompatActivity<TViewModel> where TViewModel : MvxViewModel
{
public new TViewModel ViewModel
{
get { return base.ViewModel; }
set { base.ViewModel = value; }
}
}
I get this error on the OnCreate of my Activity:
Failed resolution of: Landroid/support/v7/appcompat/R$drawable; Didn't
find class "android.support.v7.appcompat.R$drawable" on path:
DexPathList...
But if I change MvxAppCompatActivity to MvxActivity it works fine...why?
I downloaded your solution and tried to build the Android project. It fails with 18 occurrences of the same error:
error: No resource identifier found for attribute 'loginButtonBackgroundColor' in package ...
So after a little inspection of your solution, I did the following steps to solve your issue:
1) In login_screen.axml I saw you had this line:
xmlns:[YOURNAMESPACE]="http://schemas.android.com/apk/res/[YOUR PACKAGE]"
Which is unnecessary. After removing it, and changing the lines [YOURNAMESPACE]:loginButtonBackgroundColor=... to local:loginButtonBackgroundColor=... the build succeeds.
2) I saw some layout files are located inside the /drawable folder (button_round_corner.xml, input_box.xml and login_button.xml). I moved them to the /layout folder and fixed the issues the change produced (only two).
3) Made Setup class inherit from MvxAppCompatSetup.
4) Added a RegisterAttribute over the LoginButton control. So the class definition looks like this:
using Android.Runtime;
...
namespace Xxx.Droid.Components
{
[Register(nameof(LoginButton))]
public class LoginButton : FrameLayout, IMvxNotifyPropertyChanged
{
...
}
}
And that's it! Probably (2) was not necessary, but leaving it here just in case.
It could be several things but it is probably the lack of some android support packages. Mainly the lack of Xamarin.Android.Support.Design gives that error. So check if you have that added and if not add it and it should solve your problem.
If it doesn't it's highly likely you lack some other android support packages
I'm playing around with Grails/Groovy and have some straight Groovy code working that utilizes groovy-wslite. That code starts as such
send-request.groovy
#Grab(group='com.github.groovy-wslite', module='groovy-wslite', version='1.1.0')
import wslite.soap.*
When I implement that into my Grails code and view the controller/action I get this
Error 500: Internal Server Error
URI: /FormProj/hello/trigger
Class: java.lang.RuntimeException
Message: No suitable ClassLoader found for grab
And here's the code in it's current state (I've tried a LOT of different things)
HelloController.groovy
package com.demo
import groovy.grape.Grape
class HelloController {
def index() { }
def sayHi() {
return [
greeting : "Hi there, ${ params.name }"
]
}
def trigger() {
Grape.grab(group:'com.github.groovy-wslite', module:'groovy-wslite', version:'1.1.0')
…
}
}
As I'm sure you notice I'm very green with Grails/Groovy and really all things Java. I do know there is a wslite plugin for Grails, but surely this can work too right?
Grails: 2.3.8
Groovy: 2.2.2
UPDATE
Based on Ian Robert's advice I have updated my BuildConfig file by adding this line to the dependencies block
compile 'com.github.groovy-wslite:groovy-wslite:1.1.0'
And updated my controller to look like this
HelloController.groovy
package ws.thejspot
import wslite.soap.*
class HelloController {
def index() { }
def sayHi() {
return [
greeting : "Hi there, ${ params.name }"
]
}
def trigger() {
def client = new SOAPClient('URL')
}
}
Unfortunately now the IDE, GGTS, shows an error in the controller 'unable to resolve class SOAPClient'
Rather than trying to download the dependencies with #Grab, you should use the standard Grails dependency mechanism - edit grails-app/conf/BuildConfig.groovy and look for the grails.project.dependency.resolution closure. Inside that, in the dependencies block you should add
compile 'com.github.groovy-wslite:groovy-wslite:1.1.0'
and remove anything Grape-related from the controller, leaving just the import wslite.soap.*
You will probably need to run
grails compile --refresh-dependencies
at least once to ensure that Grails picks up your change to BuildConfig - it deliberately doesn't do a full dependency resolve every time you compile, so as not to slow down the build too much, so you need to tell it to refresh when you know it needs to.
I have built a new basic grails project. I have a basic java object I've written outside of grails, and jarred up. I've added the jar file to the grails project, via the properties > Java build path > Libraries tab > Add Jars.
Then I try to access it in a grails controller, and get a class def not found error.
What am I doing wrong?
TestController.groovy
package testproject
import test.TestClass
class TestController {
def index() {
def testClass = new TestClass()
render 'Index page'
}
}
and:
in the jar, TestClass.java
package test;
public class TestClass {
private String string;
public void setString(String string)
{
this.string = string;
}
public String getString()
{
return string;
}
}
The error is:
C:\Users\One\TestProject\grails-app\controllers\testproject\TestController.groov
y: 3: unable to resolve class test.TestClass # line 3, column 1.
import test.TestClass
The STS classpath generated from the Grails classpath, but it's unidirectional. Adding items in STS has no effect on Grails.
Put the jar file in your lib directory and run grails compile --refresh-dependencies. Then re-sync STS from Grails by right-clicking the project node in the tree and running Grails Tools | Refresh Dependencies.
You still need to import it in the Grails controller.
import your.java.ClassName
I'm working through the book Grails: A Quick-Start Guide and have come upon a problem. The book has me install the Blurb plugin, which seems to work, but states that we will be using it as if it were a domain class and using it a pre-existing controller. The code that I am to add to the controller looks like this
def blurb = Blurb.findByName("custom_${event.id}" )
if (!blurb){
blurb = new Blurb(name:"custom_${event.id}" , content:"" ).save()
}
When I do this I receive the same error in the IDE and the run output
'unable to resolve class Blurb' and I am directed specifically to this line blurb = new Blurb(name:"custom_${event.id}" , content:"" ).save()
Can anyone tell me what might be going wrong? I'm assuming the plugin is installed properly because if I try to access it's controller/action directly 'http://localhost:8080/TekDays/blurb/create' the plugin's provided view renders properly.
Thanks!

For reference I am using STS / Grails 1.3.7
Update 2011.05.12 7:45AM CST
I've attached a screenshot showing my project from the STS interface to show how my project is laid out in the event that it is package related as Burt indicated. The issue though is I'm not sure how do to the import statement so perhaps that screenshot will help.
Here is the current code in the Dashboard Controller.
package tekdays
class DashboardController {
...
}
I've tried adding the following lines per Burt's suggestion, but I obviously don't have it right
package tekdays
package my.package <--unexpected token: package
class DashboardController {
I tried changing out my with tekdays and default and both yield the same result.
Am I doing that wrong?
Thanks!
The Blurb class is in the default package, so if your controller is in a package you'll need to use a Groovy trick to access it:
package my.package
import Blurb as Blurb
class MyController {
def action = {
def blurb = Blurb.findByName("custom_${event.id}" )
if (!blurb) {
blurb = new Blurb(name:"custom_${event.id}" , content:"" ).save()
}
}
}
I've tried to use the new Groovy Grape capability in Groovy 1.6-beta-2 but I get an error message;
unable to resolve class com.jidesoft.swing.JideSplitButton
from the Groovy Console (/opt/groovy/groovy-1.6-beta-2/bin/groovyConsole) when running the stock example;
import com.jidesoft.swing.JideSplitButton
#Grab(group='com.jidesoft', module='jide-oss', version='[2.2.1,)')
public class TestClassAnnotation {
public static String testMethod () {
return JideSplitButton.class.name
}
}
I even tried running the grape command line tool to ensure the library is imported. Like this;
$ /opt/groovy/groovy-1.6-beta-2/bin/grape install com.jidesoft jide-oss
which does install the library just fine. How do I get the code to run/compile correctly from the groovyConsole?
There is still some kinks in working out the startup/kill switch routine. For Beta-2 do this in it's own script first:
groovy.grape.Grape.initGrape()
Another issue you will run into deals with the joys of using an unbounded upper range. Jide-oss from 2.3.0 onward has been compiling their code to Java 6 bytecodes, so you will need to either run the console in Java 6 (which is what you would want to do for Swing anyway) or set an upper limit on the ranges, like so
import com.jidesoft.swing.JideSplitButton
#Grab(group='com.jidesoft', module='jide-oss', version='[2.2.1,2.3.0)')
public class TestClassAnnotation {
public static String testMethod () {
return JideSplitButton.class.name
}
}
new TestClassAnnotation().testMethod()
I finally got it working for Groovy Shell (1.6.5, JVM: 1.6.0_13). This should be documented better.
First at the command line...
grape install org.codehaus.groovy.modules.http-builder http-builder 0.5.0-RC2
Then in groovysh...
groovy:000> import groovy.grape.Grape
groovy:000> Grape.grab(group:'org.codehaus.groovy.modules.http-builder', module:'http-builder', version:'0.5.0-RC2')
groovy:000> def http= new groovyx.net.http.HTTPBuilder('http://rovio')
===> groovyx.net.http.HTTPBuilder#91520
The #grab is better used in a file than the shell.
Ok. Seems like this a short working demo (running from the groovyConsole)
groovy.grape.Grape.initGrape()
#Grab(group='com.jidesoft', module='jide-oss', version='[2.2.1,2.3.0)')
public class UsedToExposeAnnotationToComplier {}
com.jidesoft.swing.JideSplitButton.class.name
When run it produces
Result: "com.jidesoft.swing.JideSplitButton"
Very cool!!
The import statement must appear after the grabs.
Ps. At least one import statement must exists after the grabs
#Grab(group='com.jidesoft', module='jide-oss', version='[2.2.1,)')
import com.jidesoft.swing.JideSplitButton
public class TestClassAnnotation {
public static String testMethod () {
return JideSplitButton.class.name
}
}
Different example using latest RC-2 (note: Grab annotates createEmptyInts):
// create and use a primitive array
import org.apache.commons.collections.primitives.ArrayIntList
#Grab(group='commons-primitives', module='commons-primitives', version='1.0')
def createEmptyInts() { new ArrayIntList() }
def ints = createEmptyInts()
ints.add(0, 42)
assert ints.size() == 1
assert ints.get(0) == 42
Another example (note: Grab annotates getHtml):
// find the PDF links in the Java 1.5.0 documentation
#Grab(group='org.ccil.cowan.tagsoup', module='tagsoup', version='0.9.7')
def getHtml() {
def parser = new XmlParser(new org.ccil.cowan.tagsoup.Parser())
parser.parse("http://java.sun.com/j2se/1.5.0/download-pdf.html")
}
html.body.'**'.a.#href.grep(~/.*\.pdf/).each{ println it }
Another example (note: Grab annotates getFruit):
// Google Collections example
import com.google.common.collect.HashBiMap
#Grab(group='com.google.code.google-collections', module='google-collect', version='snapshot-20080530')
def getFruit() { [grape:'purple', lemon:'yellow', orange:'orange'] as HashBiMap }
assert fruit.inverse().yellow == 'lemon'
