Hi Arfoz,
this is the best example on how to _not_ do classes.
Every class should be self contained - as long as possible.
In your case you have a hard reference from one resource inside a class to
another resource inside another class.
I always tell my training course attendees that they should never do this
unless they don’t like themselves and they want to have Puppet nightmares.
In your case you can do the following hack:
make the add file class a parameterised class, set the parameter to the default
behaviour:
class addfile (
$enable_notify => Service[’tomcat’],
) {
file {‘/tmp/hello’:
ensure => file,
notify => $enable_notify,
}
}
On systems where you don’t have tomcat class included you have to declare the
class add file with parameter set to undef.
But: be aware that even this is not a good solution.
It’s just a hack.
Try to refacter your modules.
Best,
Martin
