I created a project template plugin, according to the tutorial here:
https://developer.atlassian.com/display/JIRADEV/Creating+a+Project+Template
It works fine.
But I try to avoid creating always a new workflow scheme, new issue type scheme and etc.
How to use existing ones? Removing <add-project> in <project-blueprint> is not the solution, because I don't any other element, which I can use to link to existing stuff.
Any hint would be appreciated.
And where to find the API description of: com.atlassian.jira.blueprint.api ??
