I have created a New Dynamic Project under Eclipse Helios Version, where my JRE Version is set to 1.6.
I have added Maven capabilities to the Web Application by clicking on Configure → Convert to Maven Project.
After adding this, a build error appeared in the Eclipse Problems view:
Java compiler level does not match the version of the installed Java project facet.
Unknown Faceted Project Problem (Java Version Mismatch)
Please tell me how to resolve this error (I want to have my JRE version as 1.6 only).
