Jira Plugin load problem Lookup method resolution failed; nested exception is java.lang.IllegalState

[edwardgonen]

I have a custom Jira plugin that's been working fine for few years. Now I've just changed few lines (upper case/lower case) and after building a new version Jira does not load it saying in the log:

ThreadPoolAsyncTaskExecutor::Thread 44 ERROR maksimg 888x19412x3 1vkyr35 10.66.57.128 /rest/plugins/1.0/installed-marketplace [c.a.p.osgi.factory.OsgiPlugin] Unable to start the plugin container for plugin 'com.playgileplayground.jira.playgilePlugin'

Deleting the "target" folder and rebuilding the plugin, resolves the problem

There is only one TARGET folder under your project where the Jars are. Delete it and it will be rebuild.
