The list of steps to be executed within a macro is split into setup commands, main commands and cleanup commands to ensure that new steps are added to the appropriate place in the execution order by plugins. By default, the setup and cleanup commands are set to the default list of steps which the build and shell plugins have in common. It's expected that most future plugins will also share these common setup and cleanup steps but we do provide arguments to the Macro initialiser to skip these if customisation is needed.

This plugin implements the ``kas build`` command.
|
|
|
|
When this command is executed, kas will checkout repositories, setup the
|
|
build environment and then invoke bitbake to build the targets selected
|
|
in the chosen config file.
|
|
|
|
For example, to build the configuration described in the file
|
|
``kas-project.yml`` you could run::
|
|
|
|
kas build kas-project.yml
