Maven > Update project

Вопрос
I'm having an indication that my project has errors but I don't get any error in any file. That indication is as well on Java Resources folder inside the project.
Error log
Using platform encoding (Cp1252 actually) to copy filtered resources, i.e. build is platform dependent!
An exception stack trace is not available.
Problems
An error occurred while filtering resources
line 1 - Maven configuration problem
How to remove this error in Eclipse project folder? Any ideas!

Contrary to most answers did Maven > Update Project...
not solve this problem.
I ended up with removing and re-importing the project.
Please try Maven -> Update Project resolved this problem for me
I just experienced the same issue. My project's pom serves as a child. maven update was the first thing I tried. I ended up deleting project from workspace, clearing .settings, .classpath, .project, reimporting and once again eclipse agreed to let maven play too :)
