Arch Linux User Repository

Experimented with @fiskhest's PKGBUILD file. First difference occurs when running '$ papercut-client'.

$ pwd
.../.../papercut-client-bin

$ papercut-client
bash: /usr/bin/papercut-client: No such file or directory

$ which papercut-client
which: no papercut-client in (...)

whereas with PKGBUILD 22.x a new binary was correctly created as '/usr/bin/papercut-client'

I'm stuck.

After updating the PKGBUILD file with the adequate '_print_server' and '_print_port' values, I ran '$ makepkg -sric' followed by '$ papercut-client' and eventually got a Java related error:

Error: A JNI error has occurred, please check your installation and try again

Apparently there is an issue with java versions not matching, my JRE being behind that of the compiler associated with Papercut code being installed. On a rolling release such as Arch, I don't think jumping ahead of the schedule release of JRE with class file version 54 is advised. How to get out of this bind ? By reverting to 21.2.x as @fiskhest writes below ?

I was able to get the latest 21.x release installed with the following PKGBUILD. Was unable to retrieve the URL to the install script for the latest 22.x version.
