pio ci


pio ci [OPTIONS] [SRC]


pio ci command is conceived of as “hot key” for building project with arbitrary source code structure. In a nutshell, using SRC and pio ci --lib contents PlatformIO initializes via pio project init new project in pio ci --build-dir with the build environments (using pio ci --board or pio ci --project-conf) and processes them via pio run command.

pio ci command accepts multiple SRC arguments, pio ci --lib and pio ci --exclude options which can be a path to directory, file or Glob Pattern. Also, you can omit SRC argument and set path (multiple paths are allowed denoting with :) to PLATFORMIO_CI_SRC Environment variable

For more details as for integration with the popular Continuous Integration Systems please follow to Continuous Integration page.


pio ci command is useful for library developers. It allows one to build different examples without creating own project per them.


-l, --lib

Source code which will be copied to <BUILD_DIR>/lib directly.

If pio ci --lib is a path to file (not to directory), then PlatformIO will create temporary directory within <BUILD_DIR>/lib and copy the rest files into it.


Exclude directories and/-or files from pio ci --build-dir. The path must be relative to PlatformIO project within pio ci --build-dir.

For example, exclude from project src directory:

  • examples folder

  • *.h files from foo folder

pio ci --exclude=src/examples --exclude=src/foo/*.h [SRC]
-b, --board

Build project with automatically pre-generated environments based on board settings.

For more details please look into pio project init --board.


Path to directory where PlatformIO will initialise new project. By default it’s temporary directory within your operating system.


This directory will be removed at the end of build process. If you want to keep it, please use pio ci --keep-build-dir.


Don’t remove pio ci --build-dir after build process.

-c, --project-conf

Build project using pre-configured “platformio.ini” (Project Configuration File).

-O, --project-option

Pass additional options from “platformio.ini” (Project Configuration File) to pio project init command. For example, automatically install dependent libraries pio ci --project-option="lib_deps=ArduinoJSON" or ignore specific library pio ci --project-option="lib_ignore=SomeLib".


Use multiple --project-option to pass multiple options to “platformio.ini” (Project Configuration File). One option per one argument. For example, pio ci --project-option="build_unflags = -std=gnu++11" --project-option="build_flags = -std=c++14"

-e, --environment

Process specified environments declared in pio ci --project-conf. Multiple environments are allowed.

-v, --verbose

Shows detailed information when processing environments.

This option can also be set globally using force_verbose setting or by environment variable PLATFORMIO_SETTING_FORCE_VERBOSE.
