Eclipse , Gradle , Lombok : lombog config not read while connected to RTC

I have simple gradle project in Eclipse ( neon ) that uses Lombok. Lombok is installed properly in Eclipse (version 1.16.16). The project works fine and reflects the contents from configuration file ( lombok.config) as long as the project is not connected to Rational Team Concert. Lombok still works while connected to RTC , but config file will not be read . I need Lombok to reflect config file content while still connected to RTC. If I disconnect from RTC, then it starts working fine again. Is it known issue or am I missing any configuration?
