Alternate Solution:
- Another way is to edit the project facet configuration file itself:
org.eclipse.wst.common.project.facet.core.xml
- Change the dynamic web module version in this line to 3.1 –
<installed facet="jst.web" version="3.0"/>
- And then
Maven -> Update Project
. You’ll find this file in the .settings directory within the Eclipse project.
