Atlassian-plugin.xml contains a definition of component

Hi, I create plugin for example Tutorial - Custom message (mail) handler for JIRA, but when I compiler plugin than Show error: atlassian-plugin.xml contains a definition of component. This is not allowed when Atlassian-Plugin-Key is set.
In file atlassian-plugin.xml include text:

Jira version 7.x

I believe you need to use the @ComponentImport annotation instead of including a component-import statement in your atlassian-plugin.xml file. See Atlassian Spring Scanner.

If you are defining a component in your atlassian-plugin.xml file, then you need to use the @Component annotation. Here’s the example included in the Atlassian Spring Scanner documentation:

public class ExposeToOSGIComponent
    private final IssueService issueService;
    private final InternalComponent internalComponent;

    public ExposeToOSGIComponent(@ComponentImport final IssueService issueService,final InternalComponent internalComponent)
        this.issueService = issueService;
        this.internalComponent = internalComponent;
