# Instructions for building P4Eclipse in a Linux environment
 
## Prerequisites:
 
* Java 6 or higher
* Ant 1.6 or higher
* Maven 3.x
* Eclipse Luna (4.4) or Eclipse Mars (4.5)
 
## To build 
1. Environment variables (change according to your own environment):
 
> $ export MVN=`which mvn`
> $ export VER=2015.1
> $ export CHANGE=123456
 
2. Run the script to build an updatesite
 
> $ cd src/3.7/build/p4eclipse_parent
> $ ./build_linux.sh updatesite
 
Location of the build artifact:
 
> src/3.7/build/p4eclipse_updatesite/target/p4eclipse-updatesite-***-site.zip
 
3. Unarchive the new updatesite zip file onto an empty directory (i.e. p4-eclipse-plugin):
 
> $ unzip p4eclipse-updatesite-***-site.zip
 
4. Install from the new updatesite directory:
 
* Eclipse -> Help -> Install New Software
* click "Add..."
* click "Local..."
* browse to the new unarchive p4eclipse updatesite directory
* ...and follow the normal installation procedure... 
 
Version note: Eclipse Luna (4.4) is required for the 2014.1 build. Eclipse Mars (4.5) is required for the 2015.1 build.
