That would not help. I had the same issues and my %JAVA_HOME% pointed to jdk1.8.0_45. I also had java version 1.8 language version 8 in IntelliJ "Project Settings >> Build, Execution, Deploy >> Module Compiler Version" and "Project Structure >> Modules >> Source". However this did not fix my issue.

As per this apache resource, it looks like that default source setting after Maven 3.0 is 1.5 that needs a manual override using pom.xml. I explicitly provided source and targer release to 1.8 in my pom.xml and it DID fix my issue. 

 <plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.3</version>
  <configuration>
     <source>1.8</source>
     <target>1.8</target>
  </configuration>
 </plugin>

Do this in your cmd line C:\mvn>echo %JAVA_HOME% if the output is something like C:\Program Files\Java\jdk1.X... where X is anything but number 8, then you are trying to build it with wrong jdk version.

Install jdk 1.8 and make sure your %JAVA_HOME points to that or drop the target release to 1.X.
