User format plugin doesn't work

[Yanduganov Andrey]

I develop plugin for JIRA and I need to use User Format plugin module in it.

I've added nodule (without any implementation, autogenerated code only) in my plugin but nothing happened.

Next I've added simple constructor

private final UserFormatModuleDescriptor moduleDescriptor;

public MyUserFormat(UserFormatModuleDescriptor moduleDescriptor){
    this.moduleDescriptor = moduleDescriptor;
}

Nothing happened again.

Next I've attempted to extend already existed UserFormat. I chose FullNameUserFormat. Again, no changes.

I also have attempted to add @Scanned annotation to my class and @ComponentImport to UserFormatModuleDescriptor. It's not working too.

Every time I have no User Formats select in the Look and Feel page.

JIRA has no errors when I build plugin.

Plugin is enabled (I've ckecked it on Add-ons page).

Is there any way to make it work?

Thanks.
