This is a modified version of the software that can be found on paulinternet.nl.
This version contains mostly macOS specific fixes and requires Java > 8. That said, if you try to run it on Windows or Linux it may crash or be missing some features.
This doesn't mean that you shouldn't run it on those systems! I heavily advise you to do this and report any bugs you find as issue.
Just go to the Releases page and download the file you need.
To build the application:
$ mvn clean install -DskipTests=true
You should now have a
.jar file in the
target folder. Run it.
If you use macOS, you should also have a
.app file in
target/gtasaveedit-<version>-SNAPSHOT that you can run.
