Perl Skript zum Aktualisieren eines OSGi Bundles in Apache Felix

Wenn ihr Apache Felix nutzt und die telnet Shell aktiviert habt

osgi.shell.telnet.port=6666

Könnt ihr mit folgendem Skript einfach eure Bundles aktualisieren.

#!/usr/bin/perl

use strict;
use warnings;

use Net::Telnet;

if (@ARGV != 2) {
        print "$0: [bundle name substring] [bundle jar absolute path]\n";
        exit 1;
}

my $bname = shift;
my $bfile = shift;

my $host = 'localhost';
my $port = 6666;

sub get_bundle_id($$) {
        my ($procs, $bname) = @_;
        my @proc = grep { m/$bname/i } @$procs;
        die "No bundle $bname found." unless @proc > 0;
        warn "Multiple bundles $bname found." if @proc > 1;
        $proc[0] =~ m/^\[\s*(\d+)\s*\]/;
        return $1;
}

my $prompt = '/->/';
my $telnet = new Net::Telnet ( Timeout=>10, Errmode=>'die', Prompt => $prompt);
$telnet->open(Host => $host, Port => $port);
$telnet->waitfor($prompt);

my @procs = $telnet->cmd('ps');

my $bid = get_bundle_id(\@procs, $bname);
print "Bundle id for $bname is $bid\n";
print "Updating bundle $bid with $bfile\n";

my @result = $telnet->cmd("update $bid file:$bfile");
print "Error: ", $result[0], "\n" if (@result > 0 && $result[0] =~ m/unable|error|fail/i);
print "done.\n";

Dies kann auch einfach in Maven integriert werden, dazu muss einfach sicher gestellt werden, dass das Skript im PATH vorhanden oder der Absolute Pfad angeben wird:

<!-- Directly deploy to osgi -->
<plugin>
     <artifactId>exec-maven-plugin</artifactId>
     <groupId>org.codehaus.mojo</groupId>
     <version>1.1</version>
     <executions>
	     <execution>
	       <phase>install</phase>
	       <goals>
	         <goal>exec</goal>
	       </goals>
	     </execution>
     </executions>
     <configuration>
       <executable>osgi_deploy.pl</executable>
       <arguments>
           <argument>${project.name}</argument>
           <argument>${project.build.directory}/${project.build.finalName}.jar</argument>
       </arguments>
    </configuration>
</plugin>

Die Ausführung:

$ mvn exec:exec
