In order to run the neo4j server on my Ubuntu 12.04 Vagrant VM I needed to install the Oracle/Sun JDK which proved to be more difficult than I’d expected.

I initially tried to install it via the OAB-Java script but was running into some dependency problems and eventually came across a post which specified a PPA that had an installer I could use.

I wrote a little puppet Java module to wrap the commands in:

class java($version) {
  package { "python-software-properties": }
 
  exec { "add-apt-repository-oracle":
    command => "/usr/bin/add-apt-repository -y ppa:webupd8team/java",
    notify => Exec["apt_update"]
  }
 
  package { 'oracle-java7-installer':
    ensure => "${version}",
    require => [Exec['add-apt-repository-oracle']],
  }
}

I then included this in my default node definition:

node default {
  class { 'java': version => '7u21-0~webupd8~0', }
}

Unfortunately when I ran that I ended up with the following error:

err: /Stage[main]/Java/Package[oracle-java7-installer]/ensure: change from purged to present failed: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install oracle-java7-installer' returned 100: Reading package lists...

I came across this post on Ask Ubuntu which explained a neat trick for getting around it by making it look like we’ve agreed to the licence. This is done by passing options to debconf-set-selections.

For a real server I guess you’d want some step where a person accepts the licence but since this is just for my hacking it seems to make sense.

My new Java manifest looks like this:

class java($version) {
  package { "python-software-properties": }
 
  exec { "add-apt-repository-oracle":
    command => "/usr/bin/add-apt-repository -y ppa:webupd8team/java",
    notify => Exec["apt_update"]
  }
 
  exec {
    'set-licence-selected':
      command => '/bin/echo debconf shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections';
 
    'set-licence-seen':
      command => '/bin/echo debconf shared/accepted-oracle-license-v1-1 seen true | /usr/bin/debconf-set-selections';
  }
 
  package { 'oracle-java7-installer':
    ensure => "${version}",
    require => [Exec['add-apt-repository-oracle'], Exec['set-licence-selected'], Exec['set-licence-seen']],
  }
}
