I'm trying to compile this github repository using arduino-cli and trying to change the partition scheme but I'm not being able to correctly use the command. The target board is an ESP32-DevKitC-32E and I'm using arduino-cli v0.31.0.
I'm using this command based on the example I found here.
I tried to use the exact same command but I think something might have changed since 2020 (date of the post of the above link), because the guy in that site uses --build-properties build.partitions=minspiffs,upload.maximum_size=1966080 and if I use the 1966080, the compiler tells me it cannot stat the file 1966080.csv. So, I looked inside the folder and I saw this huge_app.csv file and tried to use it instead! Still no good!
build-property doesn't take multiple options. If we try to use multiple options, one will override the others. So, I tried to compile the sketch only with --build-property build.partitions=huge_app but the problem of the size of the binary file is exactly the same.
Here is the final lines of the output of the command:

Sketch uses 1357754 bytes (103%) of program storage space. Maximum is 1310720 bytes.
Global variables use 40848 bytes (12%) of dynamic memory, leaving 286832 bytes for local variables. Maximum is 327680 bytes.
Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it.

Error during build: text section exceeds available space in board
Then, I went to the folder where the binaries are saved, somewhere in /tmp/arudino/sketches/E17.../ and I see that there is a partitions.csv file here. I check the contents and compare them with the same file partitions.csv previously compiled with no --build-property build.partitions=huge_app and I see that the contents are different, so the option is working, however, I get same error about the binary files being too big.
I have been using board-options instead of board-properties. This command lists all board options for an ESP32 dev board.

The build output shows "Maximum is 3145728 bytes" for program storage so it looks right.
arduino-cli compile -b esp32:esp32:esp32 --board-options PartitionScheme=huge_app hello/
Sketch uses 259217 bytes (8%) of program storage space. Maximum is 3145728 bytes.
Global variables use 22352 bytes (6%) of dynamic memory, leaving 305328 bytes for local variables. Maximum is 327680 bytes.
The Huge APP scheme allocates 3MB for program storage. "Maximum is 3145728 bytes" indicates to me the maximum program storage is 3,145,728 bytes ~ 3MB for the app.
Using the default 1.2MB APP, "Maximum is 1310720 bytes" indicates ~1.2MB allocated for program storage.
esp32.menu.PartitionScheme.huge_app=Huge APP (3MB No OTA/1MB SPIFFS)

esp32.menu.PartitionScheme.huge_app.upload.maximum_size=3145728
Yours only set the build.partitions property. This is the reason for the different results for the command.
The --build-property flag allows doing very advanced things, but it should be used only when absolutely necessary because it requires an in depth understanding of the Arduino boards platform framework as well as the target platform's configuration. That configuration can change from one release of the platform to another without notice since the properties are not part of the platform's public API. In this case where the platform developers have provided a nice public interface for configuring the partition scheme, it doesn't make sense to use the --build-property flag.
