How to Speed up the AEM Build Time
Recently I found out tool to speed up build time of your Maven based projects.
Maven Daemon is let's say maven wrapper tool which provides faster build time.
Some facts about Maven Daemon:
1. build executes in long living background process
2. native executable
3. use multiple CPU cores to build modules in parallel
Maven Daemon Installation
Use sdk or brew to install Maven Daemon
$ sdk install mvnd
$ brew install mvndaemon/homebrew-mvnd/mvnd
You can verify installation with
➜ ~ mvnd --version
mvnd native client 0.2.0-darwin-amd64 (0cd0b3f04692b7970fda06c206c1fbaac68fe9ce)
Terminal: org.jline.terminal.impl.PosixSysTerminal with pty org.jline.terminal.impl.jansi.osx.OsXNativePty

Maven vs Maven Daemon build time comparison
For testing purposes I will compare build times for AEM project. Project was build 2x times before measurement.
This measurement is not perfect, since a lot of factors can affect final build time (+- few seconds), but is fair enough to see a difference.
