How to use Visual Studio Code with Processing 3

That’s a shame. I got stuck in the Create Task File, on my Mac.
After I proceeded to install “processing-java”, I installed the process-vscode extension, restarted vscode, created a *pde file with basic processing code, but got the message: “No build task to run found. Configure build task” when running Create Task File command. If I click on it, it will prompt me to create some json file from template, but none seems to be adequate.
