cross-platform-installer

The project is aimed to pack executable jar file with external (non-bundled) resources into a cross-platfrom installer (based on jpackage - a Packaging Tool from JDK 14)

The installer for desired platform (MacOS, Windows, Linux) could be build only on target platform only.

Prerequisites

Native packages will be generated using tools on the target platform. You should install additional software before creating an installer

for Windows:
- Wix, a third-party tool, is required to generate msi or exe packages
for Linux:
- fakeroot and beanutils, rpm. They could be installed (on Debian, Ubuntu) simply
```
apt-get -y install fakeroot
apt-get -y install binutils
apt-get -y install rpm
```

To package an installer:

place jar file with any amount of files into assets directory
modify file jpackage.properties in order to reflect your data in application - name, main jar, main class etc.
run mvn package
the installer is created target/dist/${app.name}-{app.version}.{ext}, where {ext} is the installer's file extension. It is platform-dependent
- for MacOS - .pkg and .dmg
- for Windows - .exe and .msi
- for Linux - .deb and .rpm
