I installed JDK in Android studio, seems it's installed in ~/Library/Android/sdk/sources/android-28

Setting export JAVA_HOME=/Users/mrgloom/Library/Android/sdk/sources/android-28/ or export JAVA_HOME=/Users/mrgloom/Library/Android/sdk produce error like:

ERROR: JAVA_HOME is set to an invalid directory: /Users/mrgloom/Library/Android/sdk/sources/android-28/

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

How to specify java path for gradlew ?

Solution

Using JDK shipped with Android Studio and setting export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/Contents/Home helped me.
