Modifying DMG Setup scpt
Rename JabRef-dmg-setup.scpt script to JabRef-dmg-setup.applescript.
Only modify the JabRef-dmg-setup.applescript in the macOS Script Editor. Afterwards copy over the file and rename it to JabRef-dmg-setup.scpt.
Normally the scpt file is a binary compiled variant and the .applescript the uncompiled format but jpackage expects the sctp in uncompiled format
Generate iconsets
To generate icns files use the script under src/main/resources/icons
Install svg2png and call the script with the svg filename as first argument.
