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'
