Dear Commuinty,

i followed

http://doc.silverstripe.org/framework/en/topics/commandline
http://www.balbus.tk/creating-tasks/

but still not working in Bash :(

Every file child of /data/www/silverstripe ..so on

_ss_environment.php

global $_FILE_TO_URL_MAPPING;
$_FILE_TO_URL_MAPPING['/data/www/silverstripe'] = 'http://silverstripe.dev';

/data/www/silverstripe/mysite/code/HiTask.php

class HiTask extends BuildTask {
 
    protected $title = 'Say Hi';
 
    protected $description = 'A class that says <strong>Hi</strong>';
 
    protected $enabled = true;
 
    function run($request) {
        echo "I'm trying to say hi...";
    }
}

Shown and Runnable over http://silverstripe.dev/dev/tasks

But when i wil run

/data/www/silverstripe/sake dev/tasks/HiTask
The build task "HiTask" could not be found

same with

/data/www/silverstripe/sake dev/tasks/BuildTask 
The build task "BuildTask" could not be found

Have you tried clearing the cache? The most fool-proof method (to make sure *nothing* has been left over) is to `rm -rf /tmp/silverstripe-cache*` completely.
The build tasks are cached, so you need to remember to flush to be able to see new ones you add.

Now it works! I used flush=all 10000 times but not "rm -rf" ... Nice Framwork and CMS but to Docs are often brittle and broken :(

Lot of Thanks!

No problems!

It *should* clear with flush, so if you ever get bored and feel like diving into the internals of SilverStripe, debugging why it didn't work and either updating the documentation or fixing the bug would be much appreciated.

Yes of course, i already edit the docs and start a pull request on git project.
