Ionic app building problem

Question

I am a novice app developer, starting with Ionic and I am a Debian user.

once the app is ready and inside the app directory, I open a terminal and run the command ionic cordova build --release android, however I get the return below, he complains that the way to the sdk, jdk and Gradle are wrong, but these paths lead to the aquives.

I wonder what I can do to solve this problem.

Answer 1

Surely the problem is in setting the environment variable JAVA_HOME Installing Ionic on Windows (Explains about JAVA_HOME)

If you use Linux, just use

export JAVA_HOME={YOUR_PATH}
