Current behavior

matthijs@grubby:~/test$ arduino-cli compile -v

Error during build: no FQBN provided

When an invalid sketch.json is present, it is silently ignored.

Expected behavior

I would expect an error about sketch.json containing invalid JSON and no other messages.

Environment

• CLI version (output of arduino-cli version): arduino-cli alpha Version: 0.0.0-git Commit: Date:
• Not sure why arduino-cli version says nothing useful, but this is a locally compiled, slightly modified version based on bf364db76bd763bc5326750090005042d7058506 from Feb 26.
• OS and platform: Linux / Ubuntu Focal / amd64

This happens when you use go build instead of task build. Task build generates the data used by arduino-cli version: https://github.com/arduino/arduino-cli/blob/436277f6738c27c2ec5fe657b32827b06ad28c5d/Taskfile.yml#L217-L223

Makes sense, thanks!

We dropped support for sketch.json in favor of sketch.yaml in #1930
