Since commit b963a3b9, the server uses
BuildConfig.VERSION_NAME.

Generate this field manually for building without gradle.

The server name ending with .jar has several drawbacks:
 - meson requires the jar executable to attempt to modify it:

     <https://github.com/mesonbuild/meson/issues/4844>
 - meson warns during "ninja install"

 - some users try to execute it on the computer as a java executable

Removing the extension solves all these problems.

Gradle versions may sometimes cause problems. This script offers an
alternative.
