Run actions only if a regex based condition is met. Other parameters and behavior are the same as the run action. By default the regex is used for a find of the value parameter. Options parameter can be set to one or more of the following to modify the default behavior: literal - to treat the regex string as a literal string, exact - to require an exact match of the value, negative - to reverse the condition so a match means do NOT run action. Use one or more field parameters to set replacement variables that can be used in run script actions. This makes it possible to parameterize the script so it can be applied to more general use cases. For example, '--field project=MYPROJECT'.
