Snapcraft - Snaps are universal Linux packages

First pick the language your app is written in.

Why are snaps good for C/C++ projects?

Snaps are easy to discover and install. Millions of users can browse and install snaps graphically in the Snap Store or from the command-line.
Snaps install and run the same across Linux. They bundle the exact versions of your app’s dependencies.
Snaps automatically update to the latest version. Four times a day, users’ systems will check for new versions and upgrade in the background.
Upgrades are not disruptive. Because upgrades are not in-place, users can keep your app open as it’s upgraded in the background.
Upgrades are safe. If your app fails to upgrade, users automatically roll back to the previous revision.

In just a few steps, you’ll have an example C/C++ app in the Snap Store.

Why are snaps good for Java projects?

Simplify installation instructions, regardless of distribution, to snap install myjavaapp.
Directly control the delivery of automatic application updates.

Distributing a Java application for Linux and reaching the widest possible audience is complicated. Typically, the user has to make sure the JRE/SDK version and their environment are configured correctly. When a Linux distribution changes the delivered JRE, this can be problematic for applications. Snapcraft ensures the correct JRE is shipped alongside the application at all times.

In just a few steps, you’ll have an example Java app in the Snap Store.
