JDK Installation

usr/bin/java is where java will be installed by brew. usr/local/bin/mvn is where maven is installed. Actual location of Java is /library/java/JavaVirtualMachines/openjdk-11.0.2.jdk/Contents/Home. But it may change depending upon what version of Java you are installing.

#Export variable
export JAVA_HOME=$(/usr/libexec/java_home -v 1.7)

If you want to add any path to PATH variable, you can use below command.

#Update PATH variable
export PATH=/opt/apache-maven-3.6.0/bin:$PATH 

If you want to see value of any variable, you can use below command.

#Print variable

For installing different Java versions using cask, use below commands

#Using cask
brew tap homebrew/cask-versions
brew search java
brew cask install java7 
brew cask install java6

Some useful commands are here.

#View all installed Java versions
/usr/libexec/java_home -V
export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)
java -version
npm install -g appium-doctor

If any tool is missing, appium doctor will tell exactly which tools are not installed.

Node and Appium version compatibility

It is important that versions of Node and Appium are compatible. If node version is not compatible, appium will not work properly. e.g. When I upgraded the Node version to 10.5, appium started working without any issues. You can use NVM to manage Node version.
