grails plugin question - unable to resolve class - grails

i'm writing my first plugin,
but in test project, can't resolve the class of plugin (src/groovy)

I am guessing that you are not properly specifying the dependency between your plugin project and your app. Have you added a dependency either through the Grails plugin manager or by manually editing the buildConfig.groovy file?

How can I read a Grails 2.x project dependencies programmatically?

I have a Grails 2.x project with a BuildConfig.groovy, and I need to read the dependencies programmatically, using some kind of API that will process the file so that I can read how it would be at runtime. So far I have been unable to locate the right class in the Grails API for processing a BuildConfig.groovy.
How can I do this?
Thanks
Use this simple command to generate your dependency report -
grails dependency-report runtime

Adding in-place plugin to grails 3 project

In grails 2.x, we were allowed to add an in place plugin by adding following in BuildConfig.groovy
grails.plugin.location."my-plugin" = "../my-plugin"
My question is, can we add our local plugins similarly in-place in grails3.0 as well or there is some other way to do this in grails.
Actual purpose is to test the plugin whether it's working properly or not before pushing it to bintray.
Yes, there is. Grails 3 is based on Gradle so multi-project gradle builds solve your issue.
Basically you add dependency as:
compile project(':../my-custom-plugin')
and has to modify settings.gradle to include plugin:
include '../my-custom-plugin'
Check Grails documentation on Plugins and Multi-Project Builds in http://grails.github.io/grails-doc/latest/guide/plugins.html
Other way is to install plugin in local maven repository using gradle publishToMavenLocal command and resolve if from there, before publishing to Bintray or other dependency repository.
Additionally since Grails 3.1.1, reloading is now supported for 'inline' plugins. Check https://github.com/grails/grails-core/releases/tag/v3.1.1 and http://grails.io/post/138665751278/grails-3-gradle-multi-project-builds
It is done using grails { plugins { syntax. Copied from docs:
grails {
plugins {
compile ":hibernate"
compile project(':myplugin')
}
}
This multi-project thing is a bit too big to answer in a short post. I just recently started with it, but, thankfully, I now have the hang of it. There's a tutorial on my site with a plugin handling the domain classes and services and all other sub-projects (just one, a web application in this example) using the plugin. The code is also downloadable. Here's the link: http://www.databaseapplications.com.au/grails-multi-app.jsp Make no mistake, there are a few things to watch out for.

Grails plugin cannot depends on other grails plugin?

I am using grails 2.2.1, in windows.
I want to develop a plugin which depends on spring-security-core plugin, so I add dependency into BuildConfig.groovy of my plugin:
plugins {
compile ':spring-security-core:1.2.7.3'
}
Then in my grail application project, I specify the dependency in BuildConfig.groovy in:
grails.plugin.location."xxxxx" = "../grails-plugins/xxxx"
After that, when I try to refresh dependency of my grail application project, it always prompt
unable to resolve class org.springframework.security.authentication.UsernamePasswordAuthenticationToken
this class is a class depends on by spring-security-core plugin and my plugin use this class too.
Is it a grails bug? or I miss something? Please help, thanks in advance!
I tested here. In Grails 2.2.1 you need to set legacyResolve to true since
Grails 2.2 no longer uses the BuildConfig of the plugin for dependency
resolution and only uses data provided by POMs
When you set this and refresh dependencies the install messages of Spring Security Core will appear.

Creating and installing a grails plugin - how does my plugin access resources from a plugin its dependent upon during/after install?

This question is an extension from another question I posted here:
In Grails 2, how do you includeTargets from Gant scripts from a plugin your app is dependent upon?
I am writing a grails plugin that is a my-company specific version of the shiro plugin, ex. my-company-shiro. I set shiro as a dependency for my plugin in the BuildConfig.groovy like so:
plugins {compile(":shiro:1.1.4")}
I package the plugin and try to install it to a new grails app called foo:
foo> grails install-plugin ../my-company-shiro/grails-my-company-shiro-01.zip
No problems.
Now, I want to run a script in foo that is part of my-company-shiro which in turn references a script from the shiro plugin:
foo>grails create-auth-controller
I get the following failure:
Error Error executing script CreateAuthController: No such property: shiroPluginDir for class: .....
This occurrs b/c one of my scripts being executed tries to access one of shiro's scripts like so:
includeTargets << new File (shiroPluginDir, "/scripts/_ShiroInternal.groovy")
This reference works when I compile my plugin, but not here when I am installing it in another grails app.
Am I setting the dependency incorrectly in the BuildConfig.groovy such that shiro's files are not being included in my plugin therefor I cannot reference it?
The shiro plugin shows up in my .grails cache my-compnay-shiro/plugins/shiro-1.1.4
When I install my-company-shiro plugin to foo, in the .grails cache foo/plugins/my-company-shiro-0.1/dependencies.groovy and plugin.xml files reference shiro. I do not see any of shiro's scripts or files here, but I have no idea if they are supposed to be copied here.
Is the reference to shiroPlugin incorrect at install time?
Thanks in advance!
grails install-plugin is deprecated, you need to use BuildConfig.groovy instead. I tested here, declaring the custom plugin inside the app and it works, you can use grails.plugin.location to specify the folder of your plugin.
Considering a plugin named shiro-test, the BuildConfig should be:
grails.project.dependency.resolution = {
...
legacyResolve true // whether to do a secondary resolve on plugin installation, not advised and here for backwards compatibility
...
}
grails.plugin.location."shiro-test" = "path/to/plugin"
Then you refresh your dependencies and can run any script from shiro-test.

Including Grails Plugin Source in Grails 1.3.5 project

I want to use a snapshot version of the grails quartz plugin. The issue is, I want to be able to specify the dependency or include the source of the plugin in my project so that my coworkers and our build server don't have to download the plugin's zip file themselves.
I was able to solve this by connecting to the plugin's repository through an svn:external, and then adding the following to my BuildConfig.groovy.
grails.plugin.location."quartz" = "path/to/svn/external"
