I have eclipse 4.10, with m2eclipse plugin. I can build my project perfectly using Maven, either through command line or through [right click] -> run -> maven install.
But annoyingly, eclipse still complains that some files have compilation errors. They seem to refer to different versions from desired. This makes me worried that if I run my program from command line, I might not be running the build I desire.
How do I solve this problem? Thank you!
[UPDATE: Thanks for the reply, but Project->clean and [right click]->run->maven clean don't work either...
Running mvn clean eclipse:eclipse solved the problem! Thanks guys!
