sbt, g8 getting started

giter8 is ~= maven archetypes
https://github.com/n8han/giter8/

to install conscript do this
>>curl https://raw.github.com/n8han/conscript/master/setup.sh
it pus cs in ~/bin

some help:

scala example https://github.com/padcom/spring-example

append with EMPTY new line another sbt plugin common for user machine as
~/.sbt/plugins/plugins.sbt
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.1.0-RC1")


run as follows to create a sample project
g8 chrislewis/basic-project
(say you create testApp)

to create eclipse files

cd testApp

sbt eclipse (this create eclipse files, use Indigo to open project) !

Some linux utils

for i in `find -iname '*.jar'` ; do jar tvf $i | grep javax/xml/bind/util/JAXBResult.class && echo $i ; done;

java com.sun.org.apache.xalan.internal.xslt.EnvironmentCheck

To find files modified within 2 time range

touch -t 201112220000 start
touch -t 201112240000 stop
find . -newer start \! -newer stop

#to exclude with grep

find . -type f -newer start \! -newer stop | grep -v -e 'CVS' -e '.settings' -e 'target' -e '.classpath' -e '.project'

GIT and GitWeb Install

• 
  hope you already have apache2 installed and its conf are in
  /etc/apache2/
  copied from
  
• 
  Install Git packages as needed
  

  $ sudo apt-get install it git-core gitk gitweb
  if your apache www directory is pointing to ~/www
  $ cd ~/www/
  $ mkdir gitweb
  $ cd gitweb
  

• 
  copying gitwebfiles to local www
  

  $ cp /usr/share/gitweb/* ~/www/gitweb
  check the index.cgi has the cgi code in it
  

• 
  add gitweb directory to apache2 configuration by creating a “gitweb” file inside apache conf.d directory:
  

  $ nano /etc/apache/conf.d/gitweb
  Alias /gitweb /home/roger/www/gitweb
  
    Options FollowSymLinks +ExecCGI
    AddHandler cgi-script .cgi
  
  

• 
  $ nano /etc/gitweb.conf
  

  # path to git projects (.git)
  $projectroot = "/home/roger/z-git-repos";
  
  # directory to use for temp files
  $git_temp = "/tmp";
  
  # target of the home link on top of all pages
  #$home_link = $my_uri || "/";
  
  # html text to include at home page
  $home_text = "indextext.html";
  
  # file with project list; by default, simply scan the projectroot dir.
  $projects_list = $projectroot;
  ##$projects_list = "/home/git/projects.list";
  
  # stylesheet to use
  $stylesheet = "/gitweb/gitweb.css";
  
  # logo to use
  $logo = "/gitweb/git-logo.png";
  
  # the 'favicon'
  $favicon = "/gitweb/git-favicon.png";
  

• 
  restart apache2 web server:
  
  

  $ sudo /etc/init.d/apache2 restart
  

  Now you should be able to view gitweb listing all GIT projects under /home/roger/z-git-repos/
  http://localhost/gitweb
  
  
• 
  Your repo can be your shared local directory
  or you can have git-daemon running on local and pointing to /home/roger/z-git-repos/ as repo-root
  

  $git daemon --reuseaddr --base-path=/home/roger/z-git-repos --export-all --verbose --enable=receive-pack
  

• 
  Now steps to put a local project on this git-repo:
  say you have project which is Not in git (like bare local file system) as ~/projects-try/test-project
  with files in it like src/blah
  

  cd test-project
  test-project $ 
  test-project $ git init
  Initialized empty Git repository in /home/roger/projects-try/test-project/.git/
  test-project $ git add .
  test-project $ git commit -a -m 'Initial repo creation'
  test-project $ cd ..
  ## where ~/z-git-repos/ is repo' server's root dir , like www of apache :)
  projects-try $ git clone --bare ./test-project ~/z-git-repos/test-project.git
  Initialized empty Git repository in /home/roger/z-git-repos/test-project.git/
  projects-try $ cd ~/z-git-repos/test-project.git
  test-project.git $ git --bare update-server-info
  test-project.git $ mv hooks/post-update.sample hooks/post-update
  test-project.git $ chmod a+x hooks/post-update
  test-project.git $ touch git-daemon-export-ok
  test-project.git $ git config core.sharedRepository group
  test-project.git $ 
  
  ## then rename local ~/projects-try/test-project as ~/projects-try/test-project-junk
  then checkout the master, so that we continue the server's repo  as master
  cd ~/projects-try
  mv test-project test-project-junk
  git clone git://roger/test-project.git
  

• 
  now you have master's copy from repo's server which is shared by other users
  and you work on it as that is the master trunk
  now you can trash out the "test-project-junk"
  

linux tips

• to mount windows share on linux (ubuntu 10.04)
• sudo apt-get install samba smbfs (2 installs needed)
• using smbmount
  
  
  
  sudo smbmount "//11.145.120.61/system" "/home/rxxxx/z-shares/chris-share" -o 'user=rxxxx,pass=15'
  //for Read with Write permission
  sudo smbmount "//11.145.161.9/Users/rxxxx" "/home/rxxxx/z-shares/vdi/raj" -o username=rxxxx,password=xxxxxxxx15,rw,uid=1000
  //make sure use "id" command to look for ur UID 
• look for who is using port 8410
  
  
  netstat -tulpn | grep '8410'
• look for details of process with 'jboss' in it
  
  
  ps -afew | grep jboss
• ssh to a machine with jboss as user to machine devmachine, using ssh listening(telnet) port 8841 configured, default is 22
  
  
  ssh -P 8841 jboss@devmachine
  which prompts for password,
  
• to prevent typing password (from chris machine) everytime you can copy public key to remote box as follows
  
  
  copy from local ~/.ssh/id_rsa.pub to remote machine
  
  
  using scp -P 8841 src destn
  scp -P 8841 ~/.ssh/id_rsa.pub jboss@devmachine:/home/jboss/chris_rsa.pub
  
  
  then add this key to authorized keys file in remote box as follows
  cat /home/jboss/chris_rsa.pub >> ~/.ssh/authorized_keys
  
  
• if you do not have rsa (ssh keys) on you r local you can do as follows details about ssh
  gitosis
  
  
  ssh-keygen -t rsa

The defaults for the ssh-related commands can be altered for each account in a configuration file ~/.ssh/config (there is also a system-wide file, usually /etc/ssh/ssh_config). Each entry starts with a Host keyword.

Host *panix.com
User suominen
Compression no
Port 8841

If you want to run commands automatically when ssh login

just put this in ~/.bashrc or /etc/bash.bashrc if you want this for all users:

if [[ -n $SSH_CONNECTION ]] ; then
    echo "I'm logged in remotely"
fi

Eclipse - Helios

Download eclipse helios version from eclipse.org
the plugins, I have installed is

1. Helios
2. The Eclipse Project Updates - 
3. The Eclipse Web Tools Platform (WTP) software repository - 
4. AJDT
5. Mylyn for Eclipse Helios - 
6. Maven plugin

To Customize Eclipse FONT and Look and Feel use this link outside link or BEST LINK
1. I did as follows:
   Somewhere on your home directory, create a gtkrc file (like: ~/.gtkrc-eclipse) with following content:
   style "eclipse" {
   font_name = "Sans Condensed 8"
   }
   class "GtkWidget" style "eclipse"
   Finally, to launch eclipse, use following command line:
   
   GTK2_RC_FILES=/usr/share/themes/Clearlooks/gtk-2.0/gtkrc:/home/rxxxxxx/.gtkrc-eclipse '/home/rxxxxxx/programs/eclipse-helios/eclipse'
   
2. and launch through command line, make sure whole cmd in single line
3. But to Customize the font size in Text editor (code region) and console etc
   it is saved under workspace, so try to stick with few same workspace always:
   
4. goto windows - preferences - Appearences - colors and fonts - choose Basic text (this will apply for all)
5. Banner Font = BOLD - 9
6. Dialog Font = Regular - 9
7. Header Font = Bold 10
8. Text Editor Block Selection Font = REgular 9
9. Text Font = Regular 9
10. App Explorer/Outline View Font = Regular 9
11. If you take a look in ECLIPSE_HOME/plugins/org.eclipse.platform_4.2.0.v201206081400/css, you will find the different CSS used. On Linux, if you use the GTK style (in the Preferences/Appearances), the e4_default_gtk.css is used.
    Edit this file and change the .MPartStack section :
    
.MPartStack {
font-size: 9;
font-family: "Droid Sans";
swt-simple: false;
swt-mru-visible: false;
}

To Add Custom Builder (like my maven script to Eclipse)
1. project->properties
2. select builders
3. uncheck "Maven Project Builder" let "Java Builder" be checked
4. Create New Builder as follows:
5. click new, and select "Program" from the list available
6. key in "My Maven Builder" in Name
7. inside "Main" tab for "Location" put ${project_loc}/my-mvn.sh
8. make sure my-mvn.sh is available inside Project directory
9. inside "Main" tab for "Working Directory" put ${project_loc}
10. inside "Build Options" tab make sure these 3 options are checked
11. After a Clean
12. During Manual builds
13. During auto Builds
14. that's all, I see when I save a java file it compiles and pushes only edited java file
15. But for me it runs the script twice, I have not found a way to fix this

Maven war plugin for exploded deploy, in build/plugins pom.xml
