Find a specific class in your maven repository

martin — Thu, 08 Jan 2009 22:27:19 +0000

If you don’t want to use findjar, you can use a groovy script.

You can use the following:

It will search recursively all jar files under ‘/home/USER/.m2/repository’, just adjust the value for ‘USER’.

Please excuse the poor formatting of the code, I blame the browser for it

import java.util.jar.JarFile


if (args?.size() == 0 || args[0]?.length() == 0)

{

    println "usage with Parameters:  [pathToJarFiles]"

    println "per default /home/USER/.m2/repository will be searched"

    println

    System.exit(1)

}
def searchingClass = args[0]

def folder = args.size() > 1 ? args[1] : "/home/knm/.m2/repository"
println "groovy searching for Class $searchingClass in $folder"

def basedir = new File(folder)
// gets all jar-files in basedir

jars = []

 public void  recursedirs(File filedir)

 {

  filedir.listFiles().each

  { file ->

    if (file.isFile() && file.name.endsWith("jar") )

     { jars << file }

     else if (file.isDirectory() )

     { this.recursedirs(file) }

  }

 }

recursedirs( basedir)

files = jars

for (currentFile in files) { try { new JarFile(currentFile).entries().each {entry -> if (entry.name =~ searchingClass) { tmp = entry.name.replaceAll("/", ".").replaceAll(".class", "") println "$tmp ===> $folder/$currentFile.name" } } } catch (Throwable t) { println "\nFailed to open $currentFile.canonicalPath: ${t.toString()}" } }

Linux screenshot via cmdline

The cmdline way for a screenshot:

import myFile.png

Cursor turns into a crosshair cursor -> span an area and the screenshot will be safed as myFile.png

more cmdlines [linux-user only]

mjava — Mon, 20 Oct 2008 20:19:40 +0000

I recently learned and relearned more of common cmdlines and oneliners in bash.
Posting them gives me a place to lookup these until I enter them properly into my wiki.

linux-users follow here

copying/moving files/directories for backup:
mv originalfilename.txt{,.backup}
will result in originalfilename.txt.backup

!! will repeat the last command, usefull for adding sudo in front of it: ’sudo !!’

As for repeating the last command, you can also use the ‘^a^b’ notation. It will repeat the last command and replace the first ‘a’ with a ‘b’. Let’s see an example:

Let’s say your last command was tar xzvf somefile-version-1.16.9.tar.gz and you realized that
you should have written ‘17′ instead of ‘16′. Here’s the quickfix:
^16^17

If you look at the output of the history command, you’ll see the command-number in front of the command. You can use ‘!’ with the number:

!534

will repeat the command with the number 534.

Another usefull shortcut is + ‘_’. This will repeat the last parameter of the last command, usefull when creating new directories and then ‘cd’ into them.

LinuxSwords Wiki

mjava — Mon, 10 Sep 2007 10:01:16 +0000

I have played a while with to find a suitable wiki for me. I wanted to have a place to store cribs and I thought a wiki might be a good place for this.

You are invited to add your own stuff to it! You can found the wiki at http://stocker-knoller.ch/wiki
or at http://www.linuxswords.com/wiki. I’m still looking for a good Icon, does anyone of you know where to find tux-images? If so, please leave a comment.

Video Capturing

mjava — Sun, 17 Jun 2007 19:41:00 +0000

I was looking for a tool to capture videos from my desktop. First i tried x11rec, but the output is a *.mng file which is an outdatet movie-format. The only alternative output is a *.gif file but i wanted an mpg-file. Unfortunately fmpeg couldn’t handle the format either so I investigated a little bit more.

I finally found xVidCap which installs just fine with a *.deb file. It looks a bit old but it’s an easy to handle and pretty intuitive to use.

Ubuntu als Webapplikation

mjava — Wed, 13 Jun 2007 10:49:19 +0000

Es gibt ja bereits vielerlei Formen von Ubuntu: Kubuntu, Xubuntu, Edubuntu etc.

Nun gibt es Ubuntu neu auch als Webapplikation:Wubuntu. Man Ubuntu im Browserfenter starten. Allerdings kann die Webapplikation bis jetzt nur den Browser starten, aber vielleicht kommt ja noch mehr…

Movie-Splitten

mjava — Fri, 18 May 2007 17:14:36 +0000

Eigentlich klingt die Aufgabe einfach. Aus einem Film eine einzelne Szene rauschneiden.

Ich habe diverse Ubuntu/Linux-Tools ausprobiert mit erschreckenden Ergebnissen. Nix wollte richtig laufen: iLive, Avidemux, Shajaga, gopchop, kino, pitivi.

Alle haben versagt, oder genügen den Anforderungen nicht. iLive hat sogar meine XServer abgeschossen. Also zurück auf die commandline. Nach einer Sekunden-Suche mittels apt-cache search das mpgtx gefunden. Funktionierte tadellos! Syntax ist sogar bequemer als die Klicki-Bunti-Guis.

mpgsplit MeinFilm.mpg -s [29:34.33 - 32:22.00]
Diese Syntax ist so intuitiv, die muss man nicht mehr erklären

Das Auf der Commando-Zeile gehts doch am besten!!
