Faceted Project Problem Eclipse enviroment

Question

Hi!
I am facing this problem. Even if I have checked this post and try the solution on it, the problem is still there.

Java compiler level does not match the version of the installed Java project facet. Project-name Unknown Faceted Project Problem (Java Version Mismatch)

Any ideas?

Thanks in advance

Answer 1

Eclipse gives up a solution.
Just click right mouse over the problem, in the Problems tag, and run with another version which I was running before.

Trust Eclipse before check any other alternative ;)

Answer 2

Go to project properties, check the Project Facets section, set the correct JRE
