How to extract / unpack / unzip hudson.war in specified directory Linux / Windows and not on default?

Question

I downloaded hudson generic .war hudson.war from http://www.eclipse.org/hudson/download.php and placed in some path.

On passing command

java -jar hudson.war

It extracts / unpacks / unzips hudson.war in .hudson directory under my home directory.

I want to extract / unpack / unzip under a directory / folder which I can specify.

Can someone please help ?

I understand, such situation arises when you have limited space under your home directory.

Here are the steps and explanation for Windows and Linux

Windows:

By default java -jar hudson.war will extract .war on path %USERPROFILE%\.hudson For example in my case, in command terminal:

C:\Hudson>echo %USERPROFILE%\.hudson
C:\Users\osao.ORADEV\.hudson

This is the path where hudson.war is extracted. For extracting in userdefined directory, you need to set HUDSON_HOME environment variable

To set persistent environment variables: Right click My Computer ==> Properties ==> Advanced system settings ==> Environment Variables ==> System variables New. Make sure that HUDSON_HOME is not already there. If yes, delete it. Add HUDSON_HOME: <your specified directory>

Now open/restart command terminal. Check echo %HUDSON_HOME% it must be updated HUDSON_HOME

Now invoke java -jar hudson.war from the path where hudson.war is there. You will notice that extraction is in specified directory.

Linux:

By default extraction happens in $HOME You need to set $HUDSON_HOME Based on your SHELL: csh or bash

csh:

mkdir /home/osao/myHudsonHome
setenv HUDSON_HOME /home/osao/myHudsonHome
echo $HUDSON_HOME
java -jar hudson.war

bash:

mkdir /home/osao/myHudsonHome
export HUDSON_HOME=/home/osao/myHudsonHome
echo $HUDSON_HOME
java -jar hudson.war

I hope this will help.
