[英]How can I install openjdk 8 and sbt on mac and have openjdk 8 (not 13) the default one?
Installing java 8 and sbt with brew and/or brew cask is clearly possible, The problem I am hitting is that brew installs java 13 as sbt dependency, Installing java 8 and sbt with brew and/or brew cask is clearly possible, The problem I am hitting is that brew installs java 13 as sbt dependency,
And I do not know a general way to go back to java 8 as default, since there are so many ways potentially to opt between java version some of which i am aware include PATH, JAVA_HOME, ln -s, java_exec selector.

Another problem potentially is that brew install sbt installs brew install java which is 13, But java 8 I install it via brew cask.另一个问题可能是 brew install sbt 安装 brew install java 是 13,但是 java 8 我通过 brew cask 安装它。
The TL is saying that Java 13 or 14 might be causing some issues eg tests fails, should I push for latest versions of OpenJdk, Scala, SBT, etc? TL 说 Java 13 或 14 可能会导致一些问题,例如测试失败,我是否应该推送最新版本的 OpenJdk、Scala、ZDD195B30217E8EC0178E7DF6BC874A5Z 等?
Indeed, SDK Man is an option.事实上,SDK Man 是一种选择。 It actually works with brew also but there need to be just a few manual steps: here they are:
它实际上也可以与brew一起使用,但只需要几个手动步骤:它们是:
Installing sbt, java8, jenv & configure the shell安装 sbt、java8、jenv 并配置 shell
We used brew to install sbt (which in its turn installs java 13), and brew cask to install openjdk java 8, like this:我们使用 brew 安装 sbt (反过来安装 java 13),并使用 brew cask 安装 openjdk java 8,如下所示:
brew install sbt
brew tap AdoptOpenJDK/openjdk
brew cask install adoptjava8
We will use jenv to manage the java versions, with the information from https://github.com/Homebrew/homebrew-core/issues/31390我们将使用 jenv 管理 java 版本,信息来自https://github.com/Homebrew/homebrew-core/issues/31390
Basically the next steps are:基本上接下来的步骤是:
brew install jenv
jenv init -
echo 'eval "$(jenv init -)"' >> ~/.bash_profile
echo 'eval "$(jenv init -)"' >> ~/.zprofile
jenv add <path-to-java8-Home-Dir>
