JRE repository

To serve up HTTP content

$ cd 'JRE_REPOSITORY_LOCATION'
$ python -m SimpleHTTPServer &

Download required jres

Download the required JREs (x64) and place them in the oracle_jre/trusty/x86_64 folder. Update the oracle_jre/trusty/x86_64/index.yml with the updated jre.

To Build new buildpack

In the example we are building version 4.5

From bash:

$ git clone git@github.com:cloudfoundry/java-buildpack.git java-buildpack
$ cd java-buildpack
$ git fetch origin --tags
$ git checkout tags/v4.5 -b b4.5_oracle

Build the openjdk offline buildpack

$ cd java-buildpack
$ bundle install
$ bundle exec rake clean package OFFLINE=true PINNED=true

Rename and copy the buildpack from build\java-buildpack-offline-v4.5.zip to a location on your machine. Should be renamed: java-openjdk-buildpack-v4.5_20170911.zip

Build the oracle offline buildpack

Updates to files

• Update the config/components.yml ** Comment out the - "JavaBuildpack::Jre::OpenJdkJRE" line ** Uncomment the - "JavaBuildpack::Jre::OracleJRE" line
• Overwrite the config/oracle_jre.yml with the config/open_jdk_jre.yml ** Update the jre.repository_root key to "http://localhost:8000/oracle_jre/{platform}/{architecture}"

Build

$ cd java-buildpack
$ bundle install
$ bundle exec rake clean package OFFLINE=true PINNED=true

Rename and copy the buildpack from build\java-buildpack-offline-v4.5.zip to a location on your machine. Should be renamed: java-oracle-buildpack-v4.5_20170911.zip

Pre-requisite for building

Ruby

Install Ruby by following instruction here: https://rvm.io/rvm/install. Use the version specified in the java-buildpack/.ruby-version file.

$ curl -sSL https://get.rvm.io | bash -s stable
$ rvm install ruby-2.2.7
$ rvm use 2.2.7

If not already done add in ~/.bash_profile:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

Bundler

gem install bundler
