This is happening for me too.

Any solutions?

@mail2bhramar, @mitsest, any info about how did you get this error would be appreciated :wink:

[mitsest]

hi @siempredelao and thanks for the fast reply!

It seems my issue was the same with this : https://github.com/avast/android-butterknife-zelezny/issues/40

When I removed the double underscore, the exception disappeared.

I would strongly suggest allowing double underscore in ids though, as they tend to get pretty long e.g. fragment_my_account_payment_methods_title_first. fragment_my_account__payment_methods__title_first is more readable, no?

Ah well, I should stop now!

Thanks again for the plugin :)

Double underscore issue should have been resolved long time ago. It's probably a reintroduced bug.

It was "__" added in textview id. I had removed it and the plugin was working fine to add dependencies.
