[keycloak-user] Deploy providers

[ko lo]

I have keycloak 2.5.4
I'm trying to figure out an example domain-extension.
I registered provider using file-system. It didn't work. Not enough
dependencies
I registered provider using module. It is worked.
I want to register a provider using deploy. I added
jboss-deployment-structure.xml.
I registered using deployer keycloak. Own custom SPI (ExampleSeviceImp) is
not registered (I checked providers in tab server info). But tere is custom
end point example registered.

I execute add company and get NullPointerExeption because  Own custom SPI
 is not registered.
