I need to pass to builddesk some parameters, like version number, build number etc and I need to be able to specify some parameters in text fields using ${name} The simplest way to do that is to load a file projectname.properties on start This file contains all the properties and will have to be created by user. There is one problem though. In my case (and I guess this is quite common) most of those parameters need to be generated. I can insert this task into the flow, but it means that the file has to be loaded after that task. One way to achieve that is to create new flow item: Prepare and load properties file after that task is finished.
