How to check if plugin is installed in jira "programmatically" ?

[Victor Viana]

Does anyone know how to check if a particular plugin is installed in jira, but it has to be programmatically?

Try this:

ComponentAccessor.getPluginAccessor().isPluginEnabled(key)

Actually PluginAccessor is easier. I have updated the answer.

How do I obtain an instance of this class?

I am trying to test to see if it worked, but I think it solves.

Thank you (y)

Now leveraging its knowledge, know how to get an instance of "EventPublisher"? Now I can not get an instance of it by the builder as it has in this tutorial:

You can inject it in the comstructor as given in the example.
