I'm usinga Grails 2.5 with angularjs and works.
Now, I need to use Angular (2 or +). Also I need all the resources to be in the same project, not in two separated projects running independently.
I just he saw examples with grails 3.x but I can't upgrade grails version.
Thanks in advance.

I am having an application build on grails 2.2.4. I need to update it to grails 4.0.8 Can i upgrade directly. As i checked from various sources, i need to jump first from 2.2.4 to 3.x then thereafter 3.x to 4.x. Please suggest me optimum way to do this upgrade.
Similar to other question about Grails upgrades
Major version upgrades in Grails are rarely trivial. I'd suggest starting a new app in the target version, and migrating classes/functionalities.
In Grails framework, the effort required to update your application depends on multiple factors, such as:
The standard practices. For instance, the persistence stuff in the Grails services instead of controller or domains itself.
The underline plugins your application depends on. You would need to update to the latest version of the plugin, or in some case find an alternative approaches as the plugin may longer be maintained, or there maybe better ways of doing it. For instance, we had some custom plugin for multi-tenancy back when I started with Grails, But now, GORM has great support for multi-tenancy.
I personally think you should directly jump from Grails 2 to Grails 4 by creating a new application, and then move your source code. But, first you need to identify all the variables such as plugins or libraries.
I have a legacy grails app running on 1.3 on Java 6 with tomcat 6.
We need to upgrade to java 8 on tomcat 8.
Is it possible to upgrade grails version from 1.3 to 2.4.5.
Lot of compilation issues and some of the holder classes are missing.
Please suggest.
The easiest way we've found to upgrade between incompatible versions of Grails is to create a new application in the new version, and migrate the services/controllers/src directories into the new application.
You will need to keep in mind various changes (like the Holders classes you mentioned, which are now part of Holders in grails.util.Holders, iirc). Also, you'll probably need to upgrade any plugins you use to newer 2.4.x-compatible versions as well (specifically spring-security, etc.)
It's not an easy task, but it can be done. We've migrated from 1.x to 2.x before, and from 2.2 to 2.4, and we're currently migrating to 3.x. BTW, since you're migrating, perhaps moving to 3.x would be a better move?
Good luck!
I am working on a Grails 2.3 project, and they ask me have to do a study to see if it is possible to pass on the 3.x version of grails.
you can tell me what is it advantageous to switch to the version 3.x, and what's the best way for the update properly.
at the environment working I guess GGTS not supporting GRAILS 3.x, then it is mandatory to work with IntelliJ IDEA.
This section of official documentation covers the topic nicely
Upgrading from previous versions of Grails - Reference Documentation
http://docs.grails.org/latest/guide/upgrading.htmlv
You can also check the following presentation on the topic of the migration
Migrating from Grails 2 to Grails 3
http://www.slideshare.net/SpringCentral/migrating-from-grails-2-to-grails-3
Yes, GGTS currently does not support Grails 3.x, so IDEA Ultimate edition is probably the best choice as described in STARTING WITH GRAILS3 – CHOOSING AN IDE.
Does the remote control plugin work with Grails 3?
https://grails.org/plugin/remote-control
I see references to fixes for grails 2.4 on the product page but nothing for 3.

It doesn't appear to be supported by Grails 3.x (yet). You can find all of the Grails 3 plugins over on bintray.
And in this case, this plugin uses a custom repository at http://dl.bintray.com/alkemist/maven/ which doesn't appear to have a Grails 3 compatible version.
I'm rather new to grails and I'm about to start a new grails project. I'm very confused with what version to go with based on the tools not being ready to support the newest version. I've read version 3 was a complete rewrite from ground up which my gut says should be the version to go with considering the project is brand new, but I'm discovering none of the tools are ready for version 3.
I was successfully able to get version 3 up with intellij with out grails support and the same goes for ggts.
With that being said, I don't know how to run the app in ggts since grails-runapp doesn't work
with ggts, I used the following tutorial https://tedvinke.wordpress.com/2015/04/10/grails-3-released-installing-gradle-and-groovy-2-4-support-in-eclipseggts/ but I've been able to figure out how to get the app to run. Does anybody know how to do this?
My questions are
How do I run a Grails 3 app in GGTS.
Is it recommended to use Grails 3 at this point or should I use Grails 2
If you use Grails 3, what is the recommended IDE?
With Intellij I had to run it by going to the grails-app/init project run main. Is this the correct way to do it?
As of Grails 3 you don't need a special IDE To run Grails 3 application. all you need to do is to right-click on the Application class and execute to start your Grails application. To read more about IDE integration https://grails.github.io/grails-doc/latest/guide/introduction.html
Currently, not all plugins are upgraded to Grails 3. So if your project depends on some plugins that are not already upgraded this will be an issue. For example spring security is not upgraded yet, but there is a work around to use it.https://groups.google.com/forum/#!searchin/grails-dev-discuss/spring$20security/grails-dev-discuss/jOF0jw_BiCs/tOxd0NZpaxkJ
Finally, both Intellij community edition and GGTS supports Grails3. But if you want special grails features like GSP syntax highlighting use GGTS or IDEA Ultimate edition.
IntelliJ idea 15 is out. Try that. The support for Grails 3 is built in.
Choose Grails 3 instead of Grails 1/2 in project selection.
I have 6 projects running Grails 2 for over 1 year.
So far I have not encountered any need to upgrade them to Grails 3.
I use the latest edition of IntelliJ Ultimate 2016.2, and for the most part it works good with Grails 2. The debugger still throws a lot of EVAL errors, but I am able to evaluate my variables in real time.
The biggest problem I've encountered so far is plugins that are not compatible with Java 1.8. Some of the plugins still have to run in Java 1.7.
Lastly, I'd say if your project is still new, look into using NodeJs. It seems to be more popular than Grails at this point.
I think intellij is better for development in grails from my experience.
Grails 3 will be good choice for development. there are lot more features in there
https://dzone.com/articles/whats-new-grails-3
also document site will give you clear concept about it
http://docs.grails.org/latest/
Considering the fact that grails version 2 is different from grails version 3; it will be good if you start with version 3 and avoid the possibility of running into upgrade issues from 2.x to 3.x in the future
You can use Netbeans or Intelij. I use Netbeans.
Facing a lot of issues in Database migration in Grails 3.1.6. Not helping at all.
I think remaining a few days in version 2 will be beneficiary as long as version 3 stables.
Besides The GGTS support will be needed as Intellij IDEA 15 community edition does not support Grails. So better back to the old versions.
