How to modify the version of web and jdk when eclipse creates a maven project

 

1. First find the org.eclipse.wst.common.project.facet.core.xml file under .settings under the project

2. Modify the files inside to the jdk and web versions we need

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="java" version="1.8"/>
  <installed facet="jst.web" version="3.1"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>

                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
