Can a plugin be packaged as a JAR/WAR file similar to the way in which an entire Rails app can be packaged for deployment on JRuby?
either you want warbler or you want to make a jar.
If you need an empty rails app with that plugin, create an empty project, install the plugin and, edit config/warble.rb to copy the gems you need
If you need a jar with class files from that plugin; you need jrubyc to compile the rb files to class files that you can then turn into a jar with the java jar command. Put that jar into WEB-INF/lib of any Java app that needs those ruby classes.

Grails 3.2.5. Build.gradle has mail plugin:
compile "org.grails.plugins:mail:2.0.0.RC6"
In deploying a war to production I need to remove javax.mail-1.5.6.jar from WEB-INF/lib since that jar must be in the Tomcat lib when using a JNDI mail resource. So how do I keep the mail plugin but remove the offending jar file from the war? I knew how to do this in Grails 2.x. Via the gradle war task in build.gradle I have tried to exclude the file (doesn't work - the jar drifts in from a plugin somehow), and have tried to filter the file out. When I build the war I get two files - "app-0.1.war" and "app-0.1.war.original". The "original" file has the WEB-INF/lib/javax.mail jar filtered out, but the real, complete war still has it.
So how do I prevent that plugin jar from getting into the war file? Thanks.
One way to do it is with something like this:
war {
rootSpec.exclude '**/javax.mail*.jar'
}
(you may need to adjust depending on whether or not you want to also exclude the javax.mail-api jar file along with the javax.mail jar)

In Grails 2.5.1, is it possible to use grails command-line tasks from a binary plugin in the lib folder?
I had to modify an existing third-party plugin to get it to work properly.
I put the jar generated by the following command in my project's lib directory:
grails package-plugin --binary
When my project runs, it correctly uses my modified version of the plugin.
At build time, however, I need to run a Grails task on the command line that was provided by the plugin, but, using the binary plugin, the task does not appear to be available.
e.g., if the task was abc, when using the real plugin being referenced in the plugins section of BuildConfig.groovy, then I could run:
grails abc
Using the binary plugin in the lib folder, however, results in the task not being available from the command line.
Also, the original plugin hooked into grails war to include extra steps in the build process without changing the command line. These hooks no longer run with the binary plugin. Is there any way to reinstate the hooks for the binary plugin?
Thanks.
In recent versions of Grails install-plugin command has been deprecated. What is now the recommended way of installing a plugin that is not available via some repository. Assume the plugin is only available locally as zip file, e.g. after running grails package-plugin?
I think the easiest approach is to place the zip file in the project's lib folder and then add an entry in the BuildConfig.groovy. For example:
1. 'grails-image-tools-1.0.5.zip' placed in lib.
2. runtime ":grails-image-tools:1.0.5" added to BuildConfig.groovy
Since the dependency manager looks inside the project's lib folder as well, I don't have to worry about setting any paths etc.
EDIT:
The latest Grails version that I worked on was 2.1.1. I'm unable to check but according to #Saurabh's comment below this isn't applicable for Grails 2.4.3
EDIT2:
But #Jay says that it works with 2.4.5
I don't know if it is the correct way but we get it working:
Download and unzip the plugin in a directory within your project
Change your BuildConfig.groovy file to point to the new plugin
Example: Download webflow.zip plugin and unzip it into a plugins directory within your project. Add this line at end of your BuildConfig file
grails.plugin.location."webflow" = "plugins/webflow"
I have an app in Grails that uses a .java to manage paypal MassPay feature. Like many .java, it needs some jars that enclose the classes that jar uses. Ok, i import that jars and the errors in the .java dissapears. But now, when I try to run the app, i receive 25 messages like this:
myapproute/grails-app/controllers/com/mycompany/widget/MassPay.java:3: package com.paypal.sdk.profiles does not exist
import com.paypal.sdk.profiles.APIProfile;
That file in the MassPay.java does not throw any error, since i imported the jar where that class is enclosed. But it doesn't allow me to run the project.
Any help? thanks.
Im using Eclipse, not NetBeans (i have read that there is a bug in Netbeans)
Adding JARs to the Eclipse project build path is not sufficient to make them visible to Grails. You need to either put them in the application's lib directory and run grails compile --refresh-dependencies or (better) if the JARs are available in a Maven-compatible repository simply declare your dependencies in BuildConfig.groovy and let Grails download the JARs itself.
Run this - it will work
grails clean
In Grails, there is a variant how to include local plugin from sources. According to docs, one may type in BuildConfig.groovy:
// Useful to test plugins you are developing.
grails.plugin.location.shiro =
"/home/dilbert/dev/plugins/grails-shiro"
// Useful for modular applications where all plugins and
// applications are in the same directory.
grails.plugin.location.'grails-ui' = "../grails-grails-ui"
The problem is that it doesn't work in Grails 2.0.RC1. I've tried to do grails clean, to install plugin with grails install-plugin and to place it to BuildConfig.groovy. Still unable to resolve.
This works for me
grails.plugin.location.shiro = "/home/dilbert/dev/plugins/grails-shiro"
Where shiro is the name of the plugin (not the name of the directory it's in). Make sure the path to the plugin is either an absolute path or the relative path to the plugin from the application.
I've found that this sometimes doesn't work if the plugin is listed in application.properties or BuildConfig.groovy, so if it is, remove it, then execute grails clean and restart the app.
You can also install the plugin into your local maven cache.
The documentation speaks about this:
3.7.10 Deploying to a Maven Repository
maven-install
The maven-install command will install the Grails project or plugin artifact into your local Maven cache:
grails maven-install
This has the advantage of allowing you to include the plugin in your parent application using the more common ":plugin-name:version" syntax
Which allows your application to determine the best place to retrieve the plugin when in production. From an internal maven-repo or equivalent.
With Grails 3.x there is another way to do this. Suppose you've a grails app and plugin (source code) inside the same project directory:
/my-project
---/my-app
---/grails-shiro
To run your local plugin, you must create a settings.gradle file in the my-projectdirectory specifying the location of your application and plugin:
include 'my-app', 'grails-shiro'
Then add the dependency in your application's build.gradle:
compile project(':grails-shiro')
You've done.
Look at the plugins documentation for more information.
Surround the plugin name with quotes in case it contains dashes:
grails.plugin.location.'plugin-name-with-dashes' = "<path>"
You can add the .zip file for the plugin in your /lib and it will be installed.
Example:
compile ":myPlugin:1.0"
File:
/lib/myPlugin-1.0.zip
Note: You have to zip the content of the plugin folder.
