[developement] No plugin can be associated with this file

Hello, dear plugin developers!

I've created plugin for site filestore.com.ua. Tested it in IDEA enviorenment, everything is OK.
But when i build plugin and test it with FreeRapid, something goes wrong.

Link is captured by FRD, but when i press ADD i get error "no plugin associated with this file".
Seems like something wrong in plugin.xml or build.xml, but i just cant find what.
Please help.

Thank you,
Saikek.

I can't see anything wrong with it, but that service doesn't use ReCaptcha, so you can remove that dependency.

It sometimes recognizes captcha!!! But very often.
Strange...

Thanks for help.

Fixed, at last.
I've looked at FRD logfile, and noticed exception there, that it cant access to some fields of ..ServiceImpl.
Changed class type to public.
