Java checks are failing because the binary now looks for JavaCheck jars in "${application-path}/jars/" which resolves to /usr/bin/jars/ when the jars are actually located at /usr/share/devlauncher/jars/.
A quick fix is to move the devlauncher binary to /usr/share/devlauncher/ and add a symlink to that in /usr/bin/

Please note that it is illegal to distribute the binaries created with this script due to MultiMC's licensing. You're still fine using/distributing the PKGBUILD itself to build a local package that you won't redistribute.
If you have any issues please report them here as upstream seems unwilling to cooperate with people who are using anything other than their official binary distribution of the software.
