This patch replaces all direct invocations of sys.exit outside of the main invocation to KasUserError based exceptions. By that, only one method for returning is used and return codes can be handled consistently. In addition, this makes it possible to handle specific errors differently.

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
