This seems like a recent development because I remember installing it this way a few months ago. Any suggestions on how to properly install java8on MacOS nowadays?
这似乎是最近的发展，因为我记得几个月前以这种方式安装它。java8现在有什么关于如何在 MacOS上正确安装的建议吗？

TLDR: the java8artefact refers to the Oracle distribution, which has ceased being supported/available. If you really need java 1.8 instead of the latest versions you can take a look at AdoptOpenJDK/homebrew-openjdk.
TLDR：java8人工制品是指已停止支持/可用的 Oracle 发行版。如果您确实需要 java 1.8 而不是最新版本，您可以查看AdoptOpenJDK/homebrew-openjdk.
