| Error Could not resolve all dependencies for configuration ':testRuntime'. Type 'gradle dependencies' for more information

what must i do?

[vahidhedayati]

Just tried it under grails 3.0.9 and it worked fine. I suspect it may be related to your cache folders.

Try moving/removing .grails and .m2 folders from your users home folder and then go back into the project and try grails run-app

You will also require a configuration file, once you create an app and put in the dependency put this config file in place:

wget https://raw.githubusercontent.com/vahidhedayati/testwschat3/master/grails-app/conf/application.groovy -O grails-app/conf/application.groovy

hmm..it strange..

http://www.4shared.com/video/CZTr3Hfgce/newfile.html

look this...i already try to delete folder .grails'and .m2 ..but still cannot download that plugin

[vahidhedayati]

http://stackoverflow.com/questions/33345663/grails-3-0-with-wschat-web-socket-chat-plugin if you still have it application.yml. try putting it in build.gradle

[akiong]

oh ...sorry..thats my fault...just a mistype...you will get it after see my video from http://www.4shared.com/video/CZTr3Hfgce/newfile.html

i still don't know why i cannot install wschat plugin..

i tried to create a new project and put this line in to build.gradle compile "org.grails.plugins:wschat:3.0.3" but still get the same error

[akyong]

i get the same error too..i cannot install websocket chat plugin 3.0.3..

[vahidhedayati]

Coudn't watch that video it requires exe to be able to be executed .. that's not gonna work under linux.

https://www.youtube.com/watch?v=dkKmMaSjjeU here is a video showing it working under 3.0.5 on my local pc..

[akiong]

it's strange.... https://www.youtube.com/watch?v=3XWmrKI5WdQ&feature=youtu.be

i still confuse with that...or its because i am using windows?

[vahidhedayati]

Very much doubt it is anything related to your OS. It's most likely something related to your local setup.

I would suggest creating a new work space under intelij and trying again.

Have you tried exporting out the grails java/gradle environment config for dos and attempting to manually launch grails run app without reliance on intelij ?

I would also highly recommend testing it under another windows user account since as mentioned why would it work in my case and not yours (regardless of OS)

Also I highlighted my version of gradle right at the on the video I think its 2.6. Try updating your local gradle see if that also make a diff

I think there is also a .gradle folder in your users home folder. If updating to 2.6 hasn't done it then also try removing .gradle folder too

Have you tried exporting out the grails java/gradle environment config for dos and attempting to manually launch grails run app without reliance on intelij ? i tried,.. and i get the same error..

after i remove folder .gradle ..and run-app .. it will download again...but still using gradle 2.3...

now i am trying to update to gradle 2.6...but how?

[akiong]

i tried at another user windows account...a create a first grails application...to try install wschat ...but i got the same error.. and i try to update gradle to 2.8...but still get that error

http://stackoverflow.com/questions/17473842/gradle-not-able-to-find-dependencies-from-maven-repo " I'm not sure what went wrong, but try to check if maven and gradle are using the same .m2 repository path. It should be clearly displayed with these options:

mvn -X gradle --debug

"

Also something similar relating to proxy:

http://stackoverflow.com/questions/29536278/how-to-resolve-the-dependency-and-compile-the-junit-test-classes-using-gradle-bu

That problem is not really any errors related to the actual plugin code, its a gradle issue,

[vahidhedayati]

Try running gradle dependencies (use ./gradlew or gradlew.bat) for more information

that is what i get after i run gradle dependencies...i already update my gradle from 2.3 to 2.8

if i tried install other plugin...it works...but if i try to install wschat ...i still get error...althougt i want to try chat :(

or must i try install gradle version to 2.6?

[vahidhedayati]

2.8 worked fine for me. Its not that. Are you doing it in a new project. I would suggest doing the entire thing using msdos

grails create-app testchat cd testchat edit build.gradle add in line and grails run-app

If this is still failing look up : https://gist.github.com/vahidhedayati/46006e815cf31134d4ff

And try downloading the source of the grails 3 codebase and then using settings.gradle in the parent folder containing your wschat plugin and code:

To set up a multi project build create an appliation and a plugin in a parent directory:

$ grails create-app myapp $ grails create-plugin myplugin Then create a settings.gradle file in the parent directory specifying the location of your application and plugin:

include 'testchat', 'wschat' Finally add a dependency in your application's build.gradle on the plugin:

compile project(':wschat')

When you download hte plugin in the parent folder rename it from grails-wschat-plugin to wschat

and then try grails run-app

[akiong]

did you mean i create a new plugin....then that plugin fill wschat...?

after that...i use compile project(:wschat) <== that plugin?

| Are you doing it in a new project. I would suggest doing the entire thing using msdos

[vahidhedayati]

download:

https://github.com/vahidhedayati/grails-wschat-plugin/archive/master.zip unzip and call folder: wschat

or git clone https://github.com/vahidhedayati/grails-wschat-plugin and when cloned move grails-wschat-plugin to wschat

so the contents of https://github.com/vahidhedayati/grails-wschat-plugin sits inside a folder called wschat

grails create-app testchat | cd testchat | edit build.gradle add in line https://github.com/vahidhedayati/testwschat3/blob/master/build.gradle#L75 save file

now cd .. from teschat in this folder you (parent folder) you should have

both testchat and wschat folders

create a new file called settings.gradle add this inside it:

include 'testchat', 'wschat'

save the file

go back into testchat

grails run-app

that is a local plugin like an inline plugin on grails 2

C:\Users\User\Documents\indonesia>

whats step i do :

• download wschat from https://github.com/vahidhedayati/grails-wschat-plugin/archive/master.zip
• changet that zip's file from grails-wschat-plugin to wschat
• create-app testchat
• create a new file with name "settings.gradle" and insert include 'testchat', 'wschat' to settings.gradle...so file settings.gradle just 1 line
• then edit build.gradle in folder testchat and insert "compile project(:wschat)" in dependencies
• then grails run-app

whats wrong with my step?it strange

produced above file - its worth doing the same command on your local one and comparing the difference between two files.

It may be worth doing a full dependency comparison too if that don't help.

Your gonna need to google those errors. Not been here before.

[akiong]

Cannot resolve reloading agent JAR: Could not resolve all dependencies for configuration ':agent'..in file 2.txt okay

[vahidhedayati]

Are you behind a proxy ? (y/n) ? There appears to be something mentioned that matches a similar error above:

https://jira.grails.org/browse/GRAILS-12084

In regards to my .agent files, that is all fine, since that is the report from the working app locally. I think you need to try some gradle commands and one may work: (you may find gradle below is same as gradlew.bat locally)

gradle clean
gradle build --refresh-dependencies

grails run-app

Still failing try:

gradle run

./gradlew.bat run

[akiong]

Are you behind a proxy ? no...i amnot use proxy

[vahidhedayati]

Ok well beyond here means really trying to reconstruct the plugin at your end to figure out what or where is going wrong.

You already have the plugin locally so you can just copy the content's across, I will provide web links so its easier to understand:

For a start I would create a brand new app and start adding in the plugin dependencies locally to see if any of them are the cause:

https://github.com/vahidhedayati/grails-wschat-plugin/blob/master/build.gradle#L68-L70

   compile 'org.grails.plugins:ajax-tags:1.0.0.BUILD-SNAPSHOT'
   compile 'javax.websocket:javax.websocket-api:1.0'
   compile 'org.grails.plugins:mail:2.0.0.RC1'

If you can add them to a local app and grails run-app works. Then we could try pulling in the rest of the plugin into a the project:

https://github.com/vahidhedayati/grails-wschat-plugin/blob/master/src/main/groovy/wschat/DefaultWsChatConfig.groovy#L15-L26

@Bean
    public ServletContextInitializer myInitializer() {
        return new ServletContextInitializer() {
            @Override
            public void onStartup(ServletContext servletContext) throws ServletException {
                servletContext.addListener(WsChatEndpoint)
                servletContext.addListener(WsCamEndpoint)
                servletContext.addListener(WsChatFileEndpoint)
                servletContext.addListener(TicTacToeServer)
            }
        }
    }

You want to add above to your local apps init/{appName}/Application.groovy file:

https://github.com/vahidhedayati/testwebsocket-grails3/blob/master/grails-app/init/testsocket/Application.groovy

Then copy content of

https://github.com/vahidhedayati/grails-wschat-plugin/tree/master/grails-app

to your grails-app folder of your local app:

Copy content of: https://github.com/vahidhedayati/grails-wschat-plugin/tree/master/src/main/groovy/grails/plugin/wschat

to your src/groovy folder. {same path structure as plugin /src/main/groovy/grails/plugin/wschat}

Then try trigger run-app this should now be plugin running locally as an app.

If you can't make it work I will take a look later tonight into making the plugin into a grails 3.5 stand alone app

[akiong]

i already put this into build.gradle

compile 'org.grails.plugins:ajax-tags:1.0.0.BUILD-SNAPSHOT' compile 'javax.websocket:javax.websocket-api:1.0' compile 'org.grails.plugins:mail:2.0.0.RC1'

and run correctly

after i copy content to application.groovy .. i get this error

or am i missing other plugin?

its look like this errorr only happen for windows user ..

my friend tried too and get the same error with me..

i cannot import this

import org.springframework.boot.context.embedded.ServletListenerRegistrationBean import org.springframework.context.annotation.Bean import org.springframework.context.annotation.Configuration import org.springframework.web.socket.WebSocketHandler import org.springframework.web.socket.config.annotation.EnableWebSocket import org.springframework.web.socket.config.annotation.WebSocketConfigurer import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry import org.springframework.web.socket.handler.PerConnectionWebSocketHandler import org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor

i cannot copy that code to init/{appName}/application.groovy

but i try to run...i get a page like yours...i can set nickname and login..then page will redirect to http://localhost:8080/wsChat/chat

then

Error.... fasd disconnecting from server...

[vahidhedayati]

The above errors relate to imports take a look at https://github.com/vahidhedayati/grails-wschat-plugin/blob/master/src/main/groovy/wschat/DefaultWsChatConfig.groovy#L3-L8 you need to include the imports also take a look at the https://github.com/vahidhedayati/testwebsocket-grails3/ read me (or main page) and try to understand how you are registering those listeners.

If you can't get it working I will give it a go later and make it into an app. Later this evening

[akiong]

okay..and thank you.. 06:37 PM here :+1:

btw ... i dont have this plugin/ class

import grails.plugin.wschat.TicTacToeServer import grails.plugin.wschat.WsCamEndpoint import grails.plugin.wschat.WsChatEndpoint import grails.plugin.wschat.WsChatFileEndpoint

[vahidhedayati]

Its 12:13 pm here so my time later will be in the evening around 7:00 pm my time.. I will update this with the new github project you can download from

https://github.com/vahidhedayati/grails-wschat-plugin/blob/master/src/main/groovy/grails/plugin/wschat/TicTacToeServer.groovy ? that should be the file that then becomes the websocket listener.

I presume you have no use / time for tic tac toe games so you could just leave it out and also exclude the line that adds the listener as part of instructions..

[akiong]

what does

grails -version 

return ? it is trying to access: https://repo.grails.org/grails/core/org/grails/plugins/wschat/3.0.3/wschat-3.0.3.pom which does not exist yes.. but I wonder if you are pointing to right grails version under linux..

have a look here for some hacks in order to run any version of grails under linux:

https://github.com/vahidhedayati/documentation/blob/master/grails/.bashrc

you need a new shell connection to your console if you update this file or

. ~/.bashrc 

after updating

i am using grails 3.0.5 and groovy 2.4.4 in linux via virtualBox

i tried in another notebook with windows 7.. download grails 3.0.5

create-app testting

then run.. it will success compiled and i can access localhost:8080

then i tried put compile "org.grails.plugins:wschat:3.0.3" in to build.gradle

i get the same error...

its look like this problem only in windows user

[akiong]

i am trying to run your plugin (https://github.com/vahidhedayati/grails-wschat-plugin) and grails run-app

[vahidhedayati]

I don't understand ?

i am trying to run your plugin (grails-wschat-plugin-master) and grails run-app

Please explain ?

You have downloaded the plugin as a zip file, extracted it now it is called :

grails-wschat-plugin-master ?

from there I don't understand ? you have then gone in there and running

grails run-app ?

This is I presume Linux ?

[akiong]

i mean this https://github.com/vahidhedayati/grails-wschat-plugin..

i download as zip and extract it..then i try to grails run-app..

[vahidhedayati]

you can't do that, its the actual plugin ?

All you should need to do is create a new app and then to include the compile line inside your build.gradle for Grails 3 + or BuildConfig.groovy if grails 2 ..

If you download the plugin i.e. above, if its as a zip I presume it will be for grails 3, so refer to aboves information on having a settings.gradle outside of your created app and to include the wschat plugin with that other compile line..

https://github.com/vahidhedayati/grails-wschat-plugin/issues/9#issuecomment-151510405

[akiong]

oh i see...then my error is not that..

because i am using grails 3.0.5...its already 2 days.. i still cannot use wschat :(

i will try again to create-app using compile project(':wschat')

[akiong]

i try this step again :

• download wschat from https://github.com/vahidhedayati/grails-wschat-plugin/archive/master.zip
• changet that zip's file from grails-wschat-plugin to wschat
• create-app testchat
• create a new file with name "settings.gradle" and insert include 'testchat', 'wschat' to settings.gradle...so file settings.gradle just 1 line
• then edit build.gradle in folder testchat and insert "compile project(:wschat)" in dependencies
• then grails run-app

i always get this error: FAILURE: Build failed with an exception.

its look like something wrong with this id "io.spring.dependency-management" version "0.5.2.RELEASE" in build.gradle

[akiong]

hi..i got something..

please download this zip's file

then see /haha/wschat/build.gradle

that project run well after i remove

• //mavenBom "org.grails:grails-bom:$grailsVersion"
• //id "io.spring.dependency-management" version "0.5.2.RELEASE"

its look like my project -->haha/build.gradle already have //id "io.spring.dependency-management" version "0.5.2.RELEASE"

but i try to access localhost:8080 .. localhost:8080 image

[vahidhedayati]

i checked your build.gradle you have:

//compile project(':wschat')

Its commented out..

you need to remove the // from the start of the line...

You can also try commenting out either the plugin or your local apps io.spring.dependency to see if makes a difference.

[akiong]

ah ..i forget that...

i get this error..after re-run

image's link

is this the correct path? file:/C:/Users/User/.m2/repository/org/grails/grails-web-boot//grails-web-boot-.pom

file:/C:/Users/User/.m2/repository/org/grails/grails-web-boot with double slash // grails-web-boot-.pom

[vahidhedayati]

right I am unsure why you are getting those issues, you could try clearing out the .m2 and .gradle and .grails folders..

Grails plugins can also be locally installed and then you can refer to them as you would normally i.e. the usual typical line as described here:

https://gist.github.com/vahidhedayati/46006e815cf31134d4ff

in the plugin you run:

grails install

This then installs it to

~/.m2/repository/org/grails/plugins/wschat/

Then you add:

compile "org.grails.plugins:wschat:3.0.3"

This calls in local .m2 folder but you be back to square 1.

I am now going to put my other disk in and install a grails app that consists of the plugin, then give you a link to download a

3.0.5 grails app that will be the plugin

Hold on

But

[vahidhedayati]

https://github.com/vahidhedayati/testwschatapp created, this is now the plugin as of this current version 3.0.3 and matching ":wschat:1.24-SNAPSHOT2" for grails 2 version. The latest changed to be a grails application:

git clone https://github.com/vahidhedayati/testwschatapp

cd testwschatapp
grails run-app

or

wget https://github.com/vahidhedayati/testwschatapp/archive/master.zip -O testwschatapp.zip
unzip testwschatapp.zip
cd testwschatapp
grails run-app

This is now the plugin converted and tested/working as a grails 3.0.5 application. I hope it all works for you

[akiong]

wow..thank you... it works for me...

but i still wonder why i cannot download wschat

by the way...it look like cannot deploy..

i test to build a war from testwschatapp...

The major difference between grails 2 and 3 is that 2 relied on tomcat container, and in the case of this plugin or any other plugin I have written that uses websockets. Under grails 2 it specifically registered tomcat websocket listeners.

Under grails 3, things change to spring boot. The configuration has been changed to work with spring boot.

In theory under grails 3 you no longer need tomcat and whilst in most cases it should work fine, in the case of this plugin/app attempting to register listeners it may not go well together.

So your choices are to downgrade to grails 2.4.XX 2.5 or to use as is and refer to:

http://grails.github.io/grails-doc/3.0.8/guide/deployment.html

$ grails package

You can then run either the WAR file or the JAR using your Java installation:

java -Dgrails.env=prod -jar build/libs/mywar-0.1.jar

This will run without a tomcat container
