There's no need to build these from source. Normally, prebuilt packages
should be suffixed with -bin; but Java packages are an exception to
this. This also makes maintenance slightly easier.
From https://wiki.archlinux.org/title/AUR_submission_guidelines#Rules_of_submission:
Packages that use prebuilt deliverables, when the sources are
available, must use the -bin suffix. An exception to this is with
Java.
