Prerequisites

SUN Java 1.6

• SUN 1.6 JDK needs to be on PATH.
• Verify correct version of java is used

igor@desktop:~$ java -version
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11)
Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02, mixed mode)

Maven 3.0.3

• Download from http://maven.apache.org/download.html
• Unpack to a local folder. On *nix, I usually unpack to /opt and

 create /opt/maven symlink so I can switch between different version
 easily

• Do NOT use maven shipped with your linux distribution.
• Verify correct maven version is used

igor@desktop:~$ mvn -version
Apache Maven 3.0.3 (r1075438; 2011-02-28 12:31:09-0500)
Maven home: /opt/maven

"natives" p2 repository

This is a temporary workaround until we figure out how to build native binaries and bundles that wrap them

 mkdir -p /var/tmp/lts
 scp -r <userid>@build.eclipse.org:/home/data/users/cbi/natives \
   /var/tmp/lts/natives

cloning platform source tree

I setup single platform-aggregator git repository that references all required parts of the platform build is git submodules. The following command clones both the outer repository and all submodules

 git clone -b tycho-monolith-build --recurse-submodules \
  <userid>@dev.eclipse.org:/home/data/users/cbi/platform-aggregator.git

To update existing clone and all submodules

 git pull --recurse-submodules
 git submodule update

running the build

review maven settings.xml

To avoid getting hit by bug 365727 [1] and to make sure your local environment configuration does not interfere with LTS build, make sure build user account does not have maven settings.xml

igor@desktop:~$ ls -l ~/.m2/settings.xml
ls: cannot access /home/igor/.m2/settings.xml: No such file or directory

give maven JVM more ram

 export MAVEN_OPTS=-Xmx512m

run the build

 mvn -f eclipse-parent/pom.xml \
   clean install \
   -Dmaven.repo.local=/var/tmp/lts/localrepo

 mvn clean install \
   -Dmaven.repo.local=/var/tmp/lts/localrepo -Dmaven.test.skip=true

With primed local repository, the build takes about 7 minutes on my 4+ years old linux desktop (core 2 duo @2.8GHz, SSD).

Packaged SDK zip files are located under
