I get the following error when I start Grails.
java.lang.NullPointerException

| Error Error occurred running Grails CLI: null
My versions are follows | Grails Version: 3.1.1 | Groovy Version:
2.4.5 | JVM Version: 1.8.0_65
I had a halfbaked grails-app folder in my root folder and hence it was causing issues, once I deleted that, the error went away. I hope this helps people, who see the same issue.

Please note: Although this question involves a lib called Apache Camel I really think this is just a question about how modern Grails plugins work.
I am on Grails 2.4.2 here, and I am trying to use Apache Camel with Grails and found the Grails Routing plugin annd cannot even get it to install.
The directions say to install by issuing a grails install-plugin routing. When I do this I get:
grails install-plugin routing
Starting process on LT-IE-ZH/10.10.99.14
Loading Grails 2.4.2
|Configuring classpath
.
|Environment set to development
......Warning
|
Since Grails 2.3, it is no longer possible to install plugins using the install-plugin command.
Plugins must be declared in the grails-app/conf/BuildConfig.groovy file.
Example:
grails.project.dependency.resolution = {
...
plugins {
compile ":routing:1.3.2"
}
}
So I modify my BuildConfig.groovy like so:
plugins {
// plugins for the build system only
build ":tomcat:7.0.54"
compile ":routing:1.3.2"
...lots of other stuff omitted for brevity
}
Then the plugin says to create routes, issue a grails create-route <RouteName>. So I do exactly that:
grails create-route OrderListener

|Script 'CreateRoute' not found, did you mean:
1) CreateFilters
2) CreatePom
3) CreateApp_
4) CreateController
5) CreateHibernateCfgXml
Please make a selection or enter Q to quit:
What is going on here?!? How do I install/use this plugin?!? Am I losing my mind, or does this plugin simply not work?
Update
I run grails clean-all, then grails refresh-dependencies then grails create-route OrderListener and I get:

Whenever you make a change in BuildConfig.groovy be sure to run grails compile to trigger dependency resolution, which will download new and updated plugins and jars, and it will also compile your code which helps to ensure that things are minimally compatible at least.
But the core issue here is that the plugin's CreateRoute.groovy script is badly broken. It's missing an important include and doesn't come close to calling createArtifact correctly. As a workaround until the authors get this fixed, create a script in your app's scripts folder called CreateCamelRoute.groovy with this content:
includeTargets << grailsScript('_GrailsCreateArtifacts')
target(createCamelRoute: "Creates a new Camel Route.") {
createArtifact(type: 'Route', path: 'grails-app/routes', name: argsMap.params?.get(0) ?: 'Example', suffix: 'Route')
}
setDefaultTarget(createCamelRoute)
It's intentionally named differently from the original because if Grails finds two with the same name it asks which one to use. This way you can just run
grails create-camel-route com.foo.bar.OrderListener
and it will work. Note that I changed the example a bit to include a package - always use packages :)
I am using Grails 2.2.2 with GGTS 3.3M1. When I run my app (grails run-app) and change something in a groovy file then Grails recompiles the file. During this process the following error output occurs:

The compilation seems to work fine but the error still occurs.
This is because you are on JDK 1.7 update 21. Something 'moved' in the JDK at that version and the state clearing logic needs updating in springloaded. This is already fixed in the springloaded codebase but won't be in a new grails version for a little while. Older versions of JDK 1.7 would be fine. You can ignore the message, but it means some state was not cleared when a type was reloaded - and this means it may look like it hasn't reloaded some of the changes you might make to your types.
I am trying to run a grails 2.1.1 web app. While checking out the project from the SVN repo, it tries to do an update dependencies and fails with the following error:

I have tried deleting the jar and re-run "refresh dependencies", did not work. Tried to see if the jar file could be unzipped, and I could unzip it successfully, which tells me that the jar is not corrupt. Tried with Eclipse Juno, STS and Eclipse Indigo on Mac OS X, all of them give the same error. Have been stuck at this point for quite sometime, any help would be appreciated.
I've installed the newest Grails PayPal-Plugin (0.6.4) and got the following error:

I fixed it by renaming notify() into notifyPaypal() => Error PayPal plugin on grails 2.0.0.RC3
But the plugin seems to disturb springSecurity because I got the following error if I try to login:
| Error 2012-02-05 21:42:07,245 ["http-bio-8080"-exec-8] ERROR [/projectname].[default] - Servlet.service() for servlet [default] in context with path [/projectname] threw exception

How can I fix it?
Notice that two versions have been released since 0.6.4, and it now behaves as you asked regarding the 'notify()' method (probably thanks to your report).

When I copied my old project from my old computer and typed grails run-app in project folder, I get the following error:

Can anyone tell me what this relates to?
Thanks
You said you just copied the project, but you must have at least partially upgraded it since your error shows that you're using Grails 2.0.0. The error message has to do with the Gorm Labs plugin, which has been abandoned for over a year and is unlikely to be compatible with newer versions of Grails. I'd remove that and any usage of it and see where you get from there.
