I am also looking for a solution to this.
I can unzip and untar the files and use the testrunner, but need to install the floating license. To do that once i download the license manager and run the jar file, i need to provide an input for the tool i have the floating license available.
I need to skip the process of entering value manually.
For you automated floating license activation, you can simply copy the ".soapui" folder from a machine where a floating license is activated to an image you use for automation. This ".soapui" folder should be in the user directory (e.g. C:\Users\<username>\.soapui)
This way you can skip running the JAR file for floating license
