Set environment variables for current chef-client run - windows

Question

I'm trying to use chef to install OpenJDK, as well as downoad Eclipse and install a few plugins using p2 director on a Windows 2008 node. OpenJDK installs and I set my environment variables JAVA_HOME and add it to the path.
However, this change does not take affect until I close and re-open PowerShell. The chef-client run needs these in the current session to run the eclipse p2 director. Is there any way to do this so that I can run chef-client only once?
In my recipe for installing openJDK I included:
env "JAVA_HOME" do
value 'C:\\Program Files\\Zulu\\zulu-8'
end
env "path" do
delim ";"
value '%JAVA_HOME%\\bin'
action :modify
end
#For Command Prompt
execute "setPathCMD" do
command "set PATH=#{node['java']['path']}\\bin;%PATH%"
end
#For PowerShell
powershell_script "setPathPS" do
code <<-EOH
$env:Path="#{node['java']['path']}\\bin;$env:Path"
EOH
end
ENV['Path'] += ";C:\\Program Files\\Zulu\\zulu-8\\bin"
And in the recipe for installing the eclipse plugins I have:
if not node['eclipse']['plugins'].empty?
node['eclipse']['plugins'].each do |plugin_group|
repo, id = plugin_group.first
execute "eclipse plugin install" do
command "#{node['eclipse']['unzip_location']}/eclipse/eclipse.exe -application org.eclipse.equinox.p2.director -noSplash -repository #{repo} -installIUs #{id}"
action :run
end
end
end

Answer 1

Try using setx:
execute 'set java_home' do
command "setx -m JAVA_HOME \"C:\\Program Files\\Zulu\\zulu-8\""
only_if { ENV['JAVA_HOME'] != 'C:\\Program Files\\Zulu\\zulu-8' }
end
# Set JAVA_HOME for this process
ENV['JAVA_HOME'] = 'C:\\Program Files\\Zulu\\zulu-8'
# do something similar for path...

Put on your client.rb or solo.rb:
ENV['VAR'] = 'value'
