How to override configuration of maven-compiler-plugin. (build directory, I want to change by using profile)

I want to ignore some build errors at a specific directory by using maven's profile. I tried to do like below but it did not work. Any help will be appreciated?

Your profile looks alright. There seems to be a known issue with the maven compiler though. See this answer to a similar question for a description of the problem and a workaround.
