I am the new maintainer of a Java open source software. Historically the software was distributed as .exe, .dmg, .rpm and .deb and as the new maintainer I would like to continue to support the 3 Os. At the moment I am managing the builds for .exe and .dmg but I don’t know how the .deb and .rpm were generated. I cam across AppImage and I think it may be the solution for me, but I could not find an in-depth tutorial, hence I have the following questions:
- can someone share ressources on how to build step by step an AppImage out of Jar application ?
- is is possible to build the flatpack from windows platform or will I need to use a virtual machine for this?
Thank you in advance for your help.
