Example of how to pass parameters from one job to the next via a file and groovy magic

Groovy Hack for Jenkins

build_number = build.buildVariableResolver.resolve('PARENT_BUILD_NUMBER')
compile_job = build.buildVariableResolver.resolve('COMPILE_JOB_NAME')

println("Build number: ${build_number}")
println("Compile job: ${compile_job}")

PackagePath = "C:\\Jenkins\\jobs\\"
RutaLog = "$PackagePath\\$compile_job\\builds\\$build_number\\log"

println("Ruta log: ${RutaLog}")

id = "System version is "
file = new File(RutaLog)
file.eachLine { line ->
  if (line.contains(id)) {
    println(line)
    texto = line
    texto = texto.replace("System version is : ","")
    texto = texto.replace(" ","")
  }
}

props = new File("version.properties")
props.write("TEST_ENV="+texto+"\n")

println "Groovy script done!"
