Homebrew Maven

 



Homebrew maven locationThe installation of Apache Maven is a simple process of extracting the archive and adding the `bin` folder with the `mvn` command to the `PATH`.

  • Brew untap of an official tap you don’t use (e.g. Homebrew/homebrew-cask) will ensure it’s no longer automatically retapped; brew casks is a new command implemented in Bash to speedily output all casks available to install (like brew formulae) brew info -cask -json=v2 includes whether a cask is outdated and the currently installed versions.
  • The Maven compiler accepts this command with – target and – source versions. If we want to use the Java 8 language features, the – source should be set to 1.8. Also, for the compiled classes to be compatible with JVM 1.8, the – target value should be 1.8. The default value for both of them is the 1.6 version.
