How to build and package OpenJDK 8 on Linux
Some pre-requisites are required to build OpenJDK8 on Linux
Be sure to have git, mercurial, gcc/g++, make and required libs and some mandatory tools installed. Java 7 should be installed.
Ensure JAVA_HOME env var point to a valid Java 7 location, example for openSUSE 12.2 :
export JAVA_HOME=/opt/obuildfactory/openjdk7
export PATH=$JAVA_HOME/bin:$PATH
You could also define Java 7 to be use with OBF_JAVA7_HOME env var, ie on Mint 14 :
export OBF_JAVA7_HOME=/usr/lib/jvm/java-7-openjdk-amd64
## Ubuntu 12.x / Mint 14
sudo apt-get install git mercurial zip bzip2 unzip tar curl
sudo apt-get install ccache make gcc g++ ca-certificates ca-certificates-java
sudo apt-get install libX11-dev libxext-dev libxrender-dev libxtst-dev
sudo apt-get install libasound2-dev libcups2-dev libfreetype6-dev
sudo apt-get install build-essential ruby-dev
sudo apt-get install openjdk-7-jdk
sudo gem install fpm
sudo zypper install git-core mercurial zip bzip2 unzip tar
sudo zypper install ccache make gcc gcc-c++ ca-certificates-cacert ca-certificates-mozilla
sudo zypper install libstdc++-devel alsa-devel cups-devel xorg-x11-devel libjpeg62-devel giflib-devel
sudo zypper install curl rpm-build gpg
sudo zypper install java-1_7_0-openjdk-devel
sudo yum install git-core mercurial zip bzip2 unzip tar
sudo yum install ccache make gcc gcc-c++ libstdc++-devel
sudo yum install alsa-lib-devel cups-devel libX11-devel libXext-devel libXt-devel libXrender-devel libXtst-devel libXi-devel libjpeg-devel giflib-devel freetype-devel
sudo yum install curl rpm-build gpg
sudo yum install java-1.7.0-openjdk-devel
sudo yum install git-core mercurial zip bzip2 unzip tar
sudo yum install ccache make gcc gcc-c++
sudo yum install libstdc++-devel libstdc++-static alsa-lib-devel cups-devel libX11-devel libXext-devel libXt-devel libXrender-devel libXtst-devel libXi-devel libjpeg-devel giflib-devel freetype-devel
sudo yum install curl rpm-build gpg rpmbuild rpm-sign
sudo yum install java-1.7.0-openjdk-devel
For example, you want to build OpenJDKs in openjdkathome directory under your home directory.
mkdir ~/openjdkathome
cd ~/openjdkathome
git clone https://github.com/hgomez/obuildfactory.git
Building is activated by XBUILD env var set to true
cd ~/openjdkathome
XUSE_NEW_BUILD_SYSTEM=true XBUILD=true ./obuildfactory/openjdk8/linux/standalone-job.sh
After some minutes you should see this logs :

By default, build are performed in incremental mode, ie only updated code is recompiled, reducing overall build time.
But experience in OpenJDK show that weird things happens sometimes and it's better to start from scratch and perform a clean build.
To activate clean mode, use XCLEAN env var ie :
cd ~/openjdkathome
XCLEAN=true XUSE_NEW_BUILD_SYSTEM=true XBUILD=true ./obuildfactory/openjdk8/linux/standalone-job.sh
We have 2 ways to build native packages, stock RPM with rpmbuild and DEB/RPM using FPM
To use stock RPM packaging, use XPACKAGE env var ie :
cd ~/openjdkathome
XPACKAGE=true XCLEAN=true XUSE_NEW_BUILD_SYSTEM=true XBUILD=true ./obuildfactory/openjdk8/linux/standalone-job.sh
To activate FPM and so DEB or RPM, also use XUSE_FPM :
cd ~/openjdkathome
XUSE_FPM=true XPACKAGE=true XCLEAN=true XUSE_NEW_BUILD_SYSTEM=true XBUILD=true ./obuildfactory/openjdk8/linux/standalone-job.sh
Sample on Mint 14 (Debian) :
j2sdk-image/jre/lib/cmm/GRAY.pf
j2sdk-image/jre/lib/applet/
j2sdk-image/jre/LICENSE
j2sdk-image/jre/THIRD_PARTY_README
