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
