I am trying to realize Creating a Jira issue CRUD servlet and issue search tutorial which is in this link: https://developer.atlassian.com/server/jira/platform/creating-a-jira-issue-crud-servlet-and-issue-search/
First part of the tutorial works really well. I can see "Hello World" text in my servlet page. Second part of the tutorial is not working because of the 404 not found dead link error. There is no compile or maven error. Also i have done the atlas-package command and there is no error. When i try to upload my jar into my Jira instance (im not using container on my local there is a virtual machine with jira installed), my plugin is not working. I have tried to download and build Issue Crud plugins from github and still only "Hello World" part of the tutorial works. I don't know what to do. If needed, i can share my pom.xml, IssueCrued class and atlassian-plugin.xml file.
