[DISCUSS]Incremental build

[Edison Su]

Maven 3 doesn't support incremental 
build(https://cwiki.apache.org/MAVEN/incremental-builds.html), so it takes a 
long time(4-7mins) to make a build, even I just make a small changes in the 
source code. I know, you can specify which projects to build by using "-pl" 
instead of build whole projects. But usually, it's quite annoying, as I need to 
manually make sure incremental build works correctly.
Are there other people asking for incremental build? Maybe switch to Gradle?:)
