Unable to tag SCM with maven-release-plugin

An incomplete layout in your subversion repository may be one of the causes for this error:

mvn release:clean -e
mvn release:prepare --batch-mode -e
mvn release:perform -e

Similar error with scm:

mvn scm:tag -Dtag="Test"

------------------------------------------------
[ERROR] Provider message:
[ERROR] SVN tag failed.
[ERROR] Command output:
[ERROR] svn: E160013: Path 'http://svn.geoaire.cl/svn/sources/YourProject/tags/v0.01' does not exist in revision 91
------------------------------------------------

My project was up and running in the trunk, what else was I going to need? Maybe tags and branches? :-)

From now and on I rather prepare a shellscript (that I version too) to build up my projects in the very beginning with this three important directories:


------------------------------------------------
WORKSPACE=/srv/svn/repositories/sources/YourProject
mkdir -p $WORKSPACE
svnadmin create --fs-type fsfs $WORKSPACE
chmod 770 -R $WORKSPACE
svn mkdir file:///srv/svn/repositories/sources/YourProject/{trunk,tags,branches}
------------------------------------------------

After the doing the "svn mkdir", the two plugins worked well. This was my configuration:

Install an Ubuntu server from a pendrive

Did you know that you may install an Ubuntu server image just from a pendrive?

I downloaded the image, inserted a pendrive (be aware, it will be totally erased)...

dmesg

Just like that! Boot your server and enjoy!

A DLNA server in Debian GNU/Linux Wheezy for your Samsung Smart TV

Your home server may be configured to be a DLNA server so you can enjoy your own videos, pictures and music in a smart tv.

Of course, it is assumed you have a LAN with a linux server and a smart tv networked.

There are several open source proyects, here I use minidlna that is already available in Debian Wheezy! the new stable version.

Here it is the procedure as described here and here, and it took very little.

apt-get install minidlna

Then, you need to setup the server in /etc/minidlna.conf, my current configuration as example:

root@gatux:~# grep -o "^[a-z].*" /etc/minidlna.conf
media_dir=/srv/shared
log_level=info
port=8200
friendly_name=DLNA Server
serial=12345678
model_number=1
inotify=yes
album_art_names=Cover.jpg/cover.jpg/AlbumArtSmall.jpg/albumartsmall.jpg/AlbumArt.jpg/albumart.jpg/Album.jpg/album.jpg/Folder.jpg/folder.jpg/Thumb.jpg/thumb.jpg
notify_interval=15

(Re)build your database, I will use a cron task every day :-)

/etc/init.d/minidlna stop
minidlna -f /etc/minidlna.conf -R -d
/etc/init.d/minidlna start 

Open the tcp port 8200 in the firewall of your home linux server if it is necessary (sure it is), I use webmin but this may just do the the trick temporarily:

iptables -I INPUT -p tcp --dport 8200 -j ACCEPT

Finally, with your dlna server running, in your smart tv choose the source, a Samsung UN55ES7100 in my case:

Nice, the Debian icon is diplayed!

Descending into the directories I found my collection... well just one video in my case:

Enjoy!

Jenkins in Weblogic Application Server 12c

To deploy jenkins in Weblogic server 12c you need a little ajustment as it is described in "Install the Jenkins as a WAR to the Weblogic server".

Here a bash shellscript using "Here Documents" to do it faster:

---------------------------------------------------------------------------------------
#!/bin/bash
TARGET=$1

if [ -z "$TARGET" ] || [ ! -e $TARGET ]
then
        echo "I need an absolut path to the jenkins war!"
        exit 1
