[jira] [Commented] (KARAF-4654) Karaf shell command

["Guillaume Nodet (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KARAF-4654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15431201#comment-15431201 ] 

Guillaume Nodet commented on KARAF-4654:
----------------------------------------

As a workaround, you can define the following:
{code}
addcommand = {
  field = (($.commandSession class) getDeclaredField "processor")
  $field setAccessible true 
  processor = ($field get $.commandSession)
  $processor addcommand $args
}
{code}

You'll then be able to use:
{code}
karaf@root()> addcommand system (($.context bundle) loadClass java.lang.System)
karaf@root()> system:currentTimeMillis 
1471885410139
{code}

> The Karaf 4 documentation mentions [the ability to script|https://karaf.apache.org/manual/latest/#_leveraging_existing_java_capabilities_via_reflection]:
> {quote}
>     It's possible to create objects to create commands "on the fly":
>     karaf@root()> addcommand system (($.context bundle) loadClass java.lang.System)
> {quote}
> However this does not work, and displays the following error message:
> {quote}
>     Command not found: addcommand
> {quote}
> Is the documentation outdated, and if so what's the new way to achieve the same result?
> Thanks.
