 file.

pom.xml

1 2 3 4 5 6 7 8 9 10 11 12 13

<build>     <plugins>         <plugin>         <groupId>org.apache.maven.plugins</groupId>         <artifactId>maven-compiler-plugin</artifactId>         <version>3.1</version>         <configuration>             <source>1.7</source>             <target>1.7</target>         </configuration>     </plugin>     </plugins> </build>

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.
