Multiple File read from multiple places and update in multiple bat file as java jar version.
I am creating a Java Application to replace or a java version to an bat file. I have a folder of bat files that I want to change the java jar file version for and I don't want to manually do every bat file. I want to read the bat, find the jar file name tag (REGEX = "([^\\s]+(\\.(?i)(txt|doc|csv|pdf|jar))$)"), and replace it with a new jar version (i.e Some New jar version Here) in each bat file in the folder
