Answer 1

I had this problem while configuring my jenkins for an android project, and finally found the problem, after even formatting my pc.

The gradle just cannot find where the Android SDK is located. Adding this to .zshrc (or .bashrc, whatever shell you are using) resolved my problem:

export ANDROID_HOME=/Users/<your-user-here>/Library/Android/sdk

Don't forget to verify if the specified folder above contains the folder sdk.

Edit: I did this in a macOS environment, you should look for the correct sdk location in your OS.
