brew tap AdoptOpenJDK/openjdk
brew cask install adoptopenjdk14

Issue and fix

I got this error when install

brew install px4-dev

Error: Formulae found in multiple taps: 
       * ardupilot/px4/px4-dev
       * px4/px4/px4-dev

I run the following code to fix it:

brew untap ardupilot/px4
brew update
