Set one or more replacement variables specified using field parameters with name=value syntax or loaded from a property file. Value specified replaces any previously set variable with the same name including values set by other actions that set replacement variables. This is an example to save a previously set value: --field myIssue=@issue@. Find and replace logic is applied to the value before setting the variable providing a way to manipulate values in a script. Variables are available only within the scope of the run script they were set in.
