In Jasper Studio 6.1.1 final each time you save a report file a timestamp comment is added to the jrxml file like this:
<!-- Created with Jaspersoft Studio version 6.1.1.final using JasperReports Library version 6.1.1 -->
<!-- 2016-07-22T15:29:22 -->
This behaviour is annoying when you use a version system like SVN or Git because it marks the file as pending of commit for no reason (if no real changes were done).
Menu Windows
-> Preferences
-> Jaspersoft Studio
: uncheck the option Add timestamp information when saving the JRXML file
.
On newer versions of Jaspersoft Studio you may need to click on Compatibility
option after the Jaspersoft Studio
option (I can't test this by now).
