Maven in Eclipse: Incremental Builds - eclipse

Question

I've been looking around for a while and can't find a definite method to build Maven incrementally in Eclipse.
Currently Maven produces a .war file each time I make a change, which takes some time to compile during the the regular build process.
What's the easiest method to speed things up and just copy across the delta changes into a directory instead?
My pom.xml file:
<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 http://maven.apache.org/maven-v4_0_0.xsd">

My way using system's maven (not eclipse's internal maven):
Right-Click to the project -> Preferences -> Builders
New ... -> Program
Set C:\Program Files\apache-maven-3.3.9\bin\mvn.cmd (your directory may be different) to Location.
Set the folder where you have your pom.xml in to "Working Directory:"
Set war:war to Arguments:.
Switch to panel "Build Options" and check "During auto builds".
Now, if you ever change a file (and save) the mvn war:war is executed.
