Yes I would also totally agree with the split package approach for an optional jre. And FYI, you can find CLion a perfect example for implementing this: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=clion . Eli Schwartz via aur-general <aur-general@archlinux.org>于2017年2月6日周一 上午1:59写道：

Agree, the thing with the meta packages is a bit overcomplicated. How about a single PKGFILE, which creates two packages with the "split package" mechanism (one with, one without JRE). @uwolfer wdyt? I can prepare the code.
Perhaps you could create two split packages, one for intellij-idea-utimate-edition, one for the bundled JRE... and have the former optdepend on the latter and on the system JRE.
The four-way split, meta-package dependency is over-engineered, but without the repo package providing ${pkgbase}-jre I don't see how to do it via a clean dependency *at all*... since Arch Linux users are always expected to pay attention to pacman's output e.g. optdepends, this shouldn't pose a problem to users.
It wouldn't be the first package to *need* at-least-one-of its optdepends to be installed.
