Iterate JSON with Ruby and get a key,value in an array

I'm getting some trouble with this JSON:

{
    "ENAX-BRANCHESM-10" :
    {
        "repo":"test-ASO",
        "PATH":"/tmp/pruebaAlvaro",
        "ARTIFACTS":"example1.jar,another_one.jar,and_another.jar",
        "uri":"http://server:8081/artifactory/test-ASO",
        "created":"A705663"

    },
    "QZQP-QZQPMAN-16" : {
        "repo": "test-ASO",
        "PATH": "/tmp/pruebaAlvaro2",
        "ARTIFACTS": "test543.jar,thisisa.jar,yesanother.jar",
        "uri": "http://server:8081/artifactory/test-ASO",
        "created": "A705663"
    }
}

I'm trying to iterate through the lists to get the PATH and the ARTIFACTS values for each list, in the example there are two lists, but really there are dozens. The purpose is to know which artifact is going to be deployed to its own path. For example:

/tmp/pruebaAlvaro
example1.jar

/tmp/pruebaAlvaro 
another_one.jar

/tmp/pruebaAlvaro 
and_another.jar

/tmp/pruebaAlvaro2 
test543.jar

/tmp/pruebaAlvaro2 
thisisa.jar

/tmp/pruebaAlvaro2 
yesanother.jar

After I searched deeply I still cannot get the solution.

json = JSON.parse(your_json)
values = json.map { |_, v| { v[:PATH] => v[:ARTIFACTS].split(',') } }

You'll get the nice hash

{
  '/tmp/pruebaAlvaro' => ['example1.jar', 'another_one.jar', ...],
  '/tmp/pruebaAlvaro2' => [...]
}

And, you can iterate over it:

values.each do |path, artifacts|
  artifacts.each do |artifact|
    puts path
    puts artifact
  end
  puts
end

You'll get the same output, which you provided in the question
