Yes i was using a transformer,

I tried to do what you explained, but can't get it working.
Here is the minimal project I tried:


import  qbs.TextFile

import  qbs.FileInfo

Product  {

     name:  "Build  Tag"

     type:  "buildtag"

     targetName:  "buildtag.txt"

     Group  {

         name:  "Fake  input"

         files:  "fake.in"

         fileTags:  ["in_tag"]


     Rule  {

         inputs:  ["in_tag"]

         Artifact  {

             filePath:  "buildtag.txt"

             fileTags:  "buildtag"


         Artifact  {

             alwaysUpdated:  false

             filePath:  "fakeOutput"


         prepare:  {

             var  cmd  =  new  JavaScriptCommand();

             cmd.description  =  "Update  build  date  tag  !"

             cmd.sourceCode  =  function()  {

                 var  file  =  new  TextFile("./buildtag.txt",  TextFile.WriteOnly);

                 var  today  =  new  Date()




             return  cmd;
