bitbucket ci - question - move statement

Hello I am using BitBucket CI and my docker build is smooth. There is one gradle build statement that I need to move OUT of the docker file and into another place to be build sooner than the docker so that gradle artifact can be scanned? Where can this be moved in the [login to view URL] ? Getting this working correct is the goal. It will be nice meeting you and surely an honor. Money is tight having cancer and being out of work, but if you can do this for a cost about $12 that would be appreciated as I can not afford anything high. Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Please note project is due in two hours as this projects deadline, as this is needed asap from the time we start.
