I have an example Grails application (from Grails in Action) that was created a while ago under version 1.1.1 on a different PC.
I am now loading Grails 1.2.0 and want to revisit the app. However, when I try to run it I get this message:
Application expects grails version [1.1.1], but GRAILS_HOME is version [1.2.0] - use the correct Grails version or run 'grails upgrade' if this Grails version is newer than the version your application expects.
After reading around a bit I cleared out the 1.2.0 folder under .grails in my home directory (from previous attempts while exploring the issue), ran "grails clean" and "grails upgrade" (answering "y" where prompted).
However, I consistently get "Invalid duplicate class definition" conflicts between classes in \grails\qotd\src\java and \grails\qotd\grails-app{controllers,services,conf}.
Are there any additional manual steps that I need to perform?
I understood your problem.
The solution is just modify the grails vesion to 1.2.0 in application.properties file in your application
If, as you pointed out in the comments, your /src/java contains .groovy files - that could definitely cause unexpected behavior. I haven't hit your particular issue, but any time I had a .groovy file mismatched with the class name inside it, I'd get strange compilation issues - so I guess you could be having a similar issue.
If you have files / classes with the same names in two locations, that's the likely culprit. If you have .groovy files in /src/java, that's another potential source.
Also, putting BootStrap, Config, DataSource and URLMappings into /src/java, that's another potential source of issues. I'd clear out your /src/java by making sure all the files are in their appropriate places under grails-app.
You can upgrade grails version with 5 steps
Project -> Clean
application.properties -> Change app.grails.version
Your project -> Properties -> Grails -> Change grails installation
to new grails version.
Your project -> Grails tools -> Refresh Dependencies
I think this may be help you

I downloaded a serverpush example called GrailsChat and trying to run is on grails 2.4.4.
I had some issues with dependencies missing that took me a while to figure out (don't think it's related but just mentioning it).
When I run grails run-app I get:
| Application metadata not found, please run: grails upgrade
When I run grails upgrade I get
| Script 'Upgrade' not found, did you mean:
1) MigrateDocs
2) IntegrateWith
3) SetGrailsVersion
4) InstallDependency
5) DependencyReport

I figure the issue is probably to do with the grails version I have being newer than the grails version that the sample app was targetting but I don't want to move back version simply to run an example (I'd rather understand the underlying issue).
Can anyone point me to some documentation that will help me understand what the application metadata is and how to move forward please?
Grails Upgrade command is removed in 2.4. You might have to upgrade the app manually following the guide.
Or you can just run the service wrapper which will download the grails version automatically base on the app.
./grailsw run-app
It seems like you have missed any one of mentioned
Not set grails proper Version
Missing application.properties file (with proper grails version)
I installed a fresh copy of GGTS on a fresh copy of windows 8 with JDK 1.7 installed.
I tried to get it to compile my existing project which was based on 2.3.6 and it failed miserably as GGTS comes with grails 2.4.2.
I know serveral people who had problems with 2.4.x so decided to stick with 2.3.
So I downloaded 2.3.11 (latest 2.3) and created a GRAILS_HOME pointing to 2.3.11 dir, and JAVA_HOME pointing to the root of the JDK.
On command line, I can now type grails - version and get back 2.3.11.
I restarted GGTS, and deleted the project and createde it again, adding 2.3.11 as a new Grails version, and set the project to use that.
It fails to compile, saying version is wrong. Fair enough. But when I try to launch the command line from GGTS using the gree circular button at the top which looks like 3 cups, it says:
Retrieving available scripts
Retrieving available scripts
An internal error occurred during: "Retrieving available scripts".
java.lang.NullPointerException
Any ideas?
In my case the problem was, that I had moved grails to a different folder. I just had to change the location of grails in the settings. Hope that helps somebody.
check all grails-project's 'app.grails.version' in application.properties, then open window - preferences - groovy -grails, make sure that all VERSIONs were defined ( I use sts, maybe a little difference ).
alternatively
update all application.properties set app.grails.version=2.3.11 ( the version your ggts defined )
Check if your environment variable of GRAILS_HOME is set to the right version of Grails.
I ran into this same issue, and the problem was caused by the Grails installation it was trying to use. It wanted to use the default version that comes with GGTS rather than the one I installed myself.
To fix, go to Window > Preferences > Groovy > Grails, then "Edit" the Grails installation it shows. I had to switch mine from C:\ggts-bundle\grails-2.4.4\ to C:\grails-2.4.2\.
I recently installed SpringSource Tool Suite. And I want to start working with Grails projects. So, I went to the Dashboard -> Extension, where I saw two extensions: Grails (current production release) and Grails Support as in the image below.
But when I try to install them, I get the following errors :
Problems occurred while performing installation: Operation details
Operation details
Cannot complete the install because one or more required items could not be found.
Software currently installed: Shared profile 1.0.0.1340820181092 (SharedProfile_com.springsource.sts.ide 1.0.0.1340820181092)
Missing requirement: Shared profile 1.0.0.1340820181092 (SharedProfile_com.springsource.sts.ide 1.0.0.1340820181092) requires 'org.maven.ide.eclipse [1.0.100.20110804-1717]' but it could not be found
What can I do to resolve this error ? Or are there any other options I can follow to install Grails extension?
Thank you!
I would switch to the new "Groovy/Grails Tool Suite" that was recently announced (see http://www.springsource.org/node/3582). Go to the standard download page at http://www.springsource.org/downloads/sts and click "Other Downloads >". Download the version for your OS under "Milestone Version - Groovy/Grails Tool Suite 3.0.0.M2".
It is a beta/milestone release but I've been using it since it was released and it's as stable as a final release so far. It's convenient since the Groovy-Eclipse plugin and the Grails support are already configured for you, in addition to the latest Grails (2.0.4). Any other plugins that you need from the standard STS can always be installed using the standard install/update procedure.
Yes, what #BurtBeckwith said. You should move to the new GGTS.
However, to address your particular problem, you installed STS into a read-only directory (or in C:\Program files). You need to re-install it somewhere else.
The Eclipse p2 installer cannot handle installing feature patches into a read-only directory. Groovy-Eclipse ships with a feature patch to extend the JDT compiler. I believe that this problem was fixed in the Juno release of Eclipse (4.2), which came out last week.
Deleting corresponding application from Windows memory removed the problem (Grails extension in SpringSource Tool Suite errors). Double running applications (earlier and new) could also be reason why GGS or STS sometimes cannot save .groovy files (with error message or without).
I have been using IntelliJ for almost a year ad I have always been really happy with it. However, yesterday I set it up on my new laptop (Ubuntu 11.04), and haven't seen the plugins module since.. :-(
Ran grails clean, tried to change the project structure/settings to include $HOME/.grails/1.3.x/projects/projectName/plugins, but still nothing. My understanding is that it should pick up the plugins automatically, am I right?
For the record, I am using Grails 1.3.4, IntelliJ IDEA Ultimate 9.0.4.
I'd strongly recommend switching to the latest Intellij version (10.5.1 as of now). Support for Grails has been improved a lot since 9.x. If you don't want to upgrade, check the following areas:
are all used classpath variables set correctly?
are you referencing the correct Grails version?
I'm using IntelliJ 11.1.3 with Grails 2.1.1.
General Issue:
The IDE Build/Make Project/Run Unit-tests sometimes fails to resolve classes referenced as dependencies within Plugins and produces 'no class...' errors. Normal grails targets (compile, run-app, test-app) work without issue!
Workaround:
Restarting IntelliJ 'magically' corrected my Plugin related 'no class...' errors.
What didn't work:
grails resolve-dependencies (makes sense because grails run-app worked fine!)
grails clean (again makes sense this is just purging the output)
Seems like the IDE Build/Make Project/Run Unit-tests uses a stale classpath in some circumstances. Unfortunately I don't have a repeatable test case but noticed that modifying BuildConfig and doing grails refresh-dependencies or compile or run-app doesn't make the IDE update it's list of grailsPlugins!
I've had IDEA do this once in a while to me as well. Even in the latest version (though I do agree you should upgrade, but 9->10 isn't free). For me, I just had to kill IDEA and restarted it.
IMPORTANT UPDATE! It will be fixed in 11.1.2! YEEAAAH!
In my case plugins not resolving because of custom system property 'grails.work.dir'. If your project using default 'grails.work.dir' than OK otherwise plugins won't be resolved. Tested on Idea 10.5.4, 11.1.1 and windows 7.
Anyone knows how to fix this ?
It works fine on my env (Me being the developer) and doesn't work on my colleagues machine who unzips the whole
Welcome to Grails null - http://grails.org/
Licensed under Apache Standard License 2.0
Grails home is set to: C:\abc\products\grails-1.1
Base Directory: C:\abc\products\foo\bar
Running script C:\abc\products\grails-1.1\scripts\RunApp.groovy
Environment set to development
Application expects grails version [1.1], but GRAILS_HOME is version [null] - us
e the correct Grails version or run 'grails upgrade' if this Grails version is n
ewer than the version your application expects.
Some clarifications
1) There has been no Grails version change , either on my machine or my colleagues machine. In fact some of them are installing for the first time
2) Under C:\Documents and Settings\myfriend.grails I can see a folder called 'null'
I tried removing this folder - but it gets created he runs my application
3) The way I am giving him the release is- I unzip the whole folder and he unzips it
SO there are three steps
A_ grails create-app to create the APp
B_ Unzip my folder to replace the generated folder
C_ Grails run-app
Things are fine after the step A- but degenerate after Step C
It appears that his Grails installation is corrupted or not set up correctly. I would have him reinstall a fresh copy of Grails - http://www.grails.org/Installation and try again.
The error that you are getting is telling us that the application that you are trying to run is identified as version 1.1 and I assume that this is correct. The fact that Grails is not able to identify what version is installed makes me point to a corrupted or mis-configured Grails installation
If he types 'grails' at the command line what does he see?
I found the problem.
This was because I had added a file- build.properties
And since the file was there- it was expecting it to have certain properties defined in it
Once I renamed it to something else- it started to work
