2.0 beta 10 cannot find user contributed library

I have an update regarding the user unfriendly format of this error:

It was the result of a bug in the Arduino CLI tool Arduino IDE 2.x uses under the hood for compiling sketches. That bug has now been fixed:

github.com/arduino/arduino-cli

Fix compile error message not printed to correct writer on error

**Please check if the PR fulfills these requirements** - [x] The PR has no du…plicates (please search among the [Pull Requests](https://github.com/arduino/arduino-cli/pulls)x before creating one) - [x] The PR follows [our contributing guidelines](https://arduino.github.io/arduino-cli/latest/CONTRIBUTING/#pull-requests) - [x] Tests for the changes have been added (for bug fixes / features) - [ ] Docs have been added / updated (for bug fixes / features) - [ ] `UPGRADING.md` has been updated with a migration guide (for breaking changes) * **What kind of change does this PR introduce?** Fixes an issue with `compile` command and related gRPC function. - **What is the current behavior?** If the user tries to compile a Sketch that includes a library that's not installed an error is printed to stderr. The gRPC interface doesn't show the error at all. ``` $ arduino-cli compile -b arduino:avr:uno /home/alien/Arduino/Blink/Blink.ino --format json /home/alien/Arduino/Blink/Blink.ino:1:10: fatal error: SD: No such file or directory #include <SD> ^~~~ compilation terminated. { "compiler_out": "", "compiler_err": "", "builder_result": { "build_path": "/tmp/arduino-sketch-302F70E5AC1B118F7324375770CFA163" }, "success": false } ``` * **What is the new behavior?** Compilation of a Sketch that includes a library not installed now correctly prints the error to the expected error stream. This also fixes the gRPC function. ``` $ arduino-cli compile -b arduino:avr:uno /home/alien/Arduino/Blink/Blink.ino --format json { "compiler_out": "", "compiler_err": "/home/alien/Arduino/Blink/Blink.ino:1:10: fatal error: SD: No such file or directory\n #include \u003cSD\u003e\n ^~~~\ncompilation terminated.\n", "builder_result": { "build_path": "/tmp/arduino-sketch-302F70E5AC1B118F7324375770CFA163" }, "success": false } ``` - **Does this PR introduce a breaking change, and is [titled accordingly](https://arduino.github.io/arduino-cli/latest/CONTRIBUTING/#breaking)?** Nope. * **Other information**: None. --- See [how to contribute](https://arduino.github.io/arduino-cli/latest/CONTRIBUTING/)

That fix is not yet in Arduino IDE 2.x, but it will be in one of the upcoming releases.
