Carlos, you are welcome.
When this happens, a file with the same name appending .new at the end is created with the installation version.
Normally these warnings are not an issue unless when are files with .jar, then is critical and very recommended to replace the local file with the .new, follows some examples of critical files:
- Move
netuno.jar.new
to netuno.jar
- Move
web/WEB-INF/lib/netuno-web.jar.new
to web/WEB-INF/lib/netuno-web.jar
Changes warnings of files inside the apps/demo and even the config.js are normal, and you can ignore these warnings.
