Appium Doctor - unable to set $JAVA_HOME/bin into PATH variable on MacOS 10.12

Question

Installed appium doctor with npm on MacOS 10.12, and it gives me one error:

WARN AppiumDoctor ✖ Bin directory for $JAVA_HOME is not set.

I've tried everything I could so far, please help. Here is my .bash_profile:

export ANDROID_HOME="/Users/sergei/Library/Android/sdk/"
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
export M2_HOME="/Users/sergei/Desktop/1246702 Sergio/apache-maven-3.3.9"
export M2=$M2_HOME/bin
export PATH=$M2:$PATH
export JYTHON_HOME="/Users/sergei/jython2.7.0/"
export JYTHON=JYTHON_HOME/bin
export PATH=JYTHON:$PATH

export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

Answer 1

Leaving the solution here, incase anyone faced similar problem in Mac Catalina, when running Appium C# script to initialise Android driver. Tried fixing .bash_profile and .zprofile files as mentioned in many answers, nothing seem to work.

Then, decided to explicitly set ANDROID_HOME and JAVA_HOME environment variables programmatically as follows, before initialising Android driver, it finally worked:

Environment.SetEnvironmentVariable("ANDROID_HOME", "/Users/{username}/Library/Android/sdk");
Environment.SetEnvironmentVariable("JAVA_HOME", "/Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home");

Answer 2

export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=${JAVA_HOME}/bin:$PATH
