Make sure your Java Project is configured probably to use Java 1.7.
Right click your project > Properties > Java Compiler and set “Compiler compliance level” to 1.7
Step2:
Java Build Path. Click “Edit“. And change it to “Java 7”

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.
