Hi,

this post describes to save and apply changes to an source file.

Let us assume you want to alter the file src/tuwien/auto/calimero/server/Launcher.java and from the changes you want to create a patch.

First make a copy of the origin file.

Then make some changes to the file and create the patch. Note the options -Nar also work for directories recursive. For a single file -u3 is sufficient.

Restore the origin file and apply the patch
