Same error for all three profiles(xmlconfig, javaconfig and javadsl):

***************************
APPLICATION FAILED TO START
***************************

Description:

A component required a bean named 'textInChannel' that could not be found.

Action:

Consider defining a bean named 'textInChannel' in your configuration.

OK, so i added:

 @Bean
    public MessageChannel textInChannel() {
        return new DirectChannel();
    }

, but now i have another error(again for all three profiles):

Any suggestions ? Any help will be appreciated..

Looks like i added quotation mark of @Profile name in spring application properties file. After fixing this silly thing everything works fine. I see that i can't delete issue, so i will only close it. Admin please delete this issue if necessary.
