How to get JarPluginArtifact from JIRA Plugin object?

[Vladimir Vasic]

When running JIRA plugin in debug mode, I can see originalPluginArtifact (JarPluginArtifact) from Plugin object in expressions window, but I can't get that property programmatically in code.
I need that in order to get jar file name (name of installed plugin jar file) based on given plugin key.
Eg:

plugin key -> tac.jira.languages.it_IT plugin jar file name -> plugin_3538044376309176990_jira-language-pack-it_IT-5.1.7-v2r22090-2012-10-15.jar

I found out workaround. I got plugin directory path: ComponentAccessor.getComponent(JiraHome.class).getPluginsDirectory()

so I made a method which check every file name within that directory, if it contains specific substring which is predefined.

One solution I can think of (a little hacky in my opinion) is to try casting the Plugin to com.atlassian.plugin.impl.DefaultDynamicPlugin - something like that:

if(p instanceof DefaultDynamicPlugin) {
	File f = ((DefaultDynamicPlugin)p).getPluginArtifact().toFile();
	f.getName()
	....
}

Just out of curiosity - why do you need the plugin jar file ?

Thanks for reply.

I need it cause I want to add some inputs in properties file which is located in jar archive (plugin). So in order to re-pack plugin I have to know its real filename on run time cause it is altered by jira sdk by adding something like plugin_353804437..._name_of_the_plugin.jar when you install plugin.

Not sure if this is your case but if you need some runtime data for the plugin maybe it's better to use Active Objects - https://developer.atlassian.com/display/DOCS/Active+Objects
