If you get the above error when you try to build a Java project using Maven, then make sure that you have the maven.compiler.source and maven.compiler.target set to java 8 or higher,

Fix:

<project xmlns="http://maven.apache.org/POM/4.0.0" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
