安装方式
从2019年5月29日开始，将通过执行以下命令来安装AdoptOpenJDK12。
1 | brew cask install adoptopenjdk |
当您要使用LTS版本时，发布信息时将显示如何指定版本和输入版本。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | brew cask info adoptopenjdk adoptopenjdk: 12.0.1,12 https://adoptopenjdk.net/ Not installed From: https://github.com/Homebrew/homebrew-cask/blob/master/Casks/adoptopenjdk.rb ==> Name AdoptOpenJDK Java Development Kit ==> Artifacts jdk-12.0.1+12 -> /Library/Java/JavaVirtualMachines/adoptopenjdk-12.0.1.jdk (Generic Artifact) ==> Caveats More versions are available in the AdoptOpenJDK tap: https://github.com/AdoptOpenJDK/homebrew-openjdk brew tap adoptopenjdk/openjdk |
因此，似乎您应该点击采用openjdk / openjdk。
1 | brew tap adoptopenjdk/openjdk |
执行此操作后，我搜索了每个版本，现在可以看到每个版本。
1 2 3 4 5 6 7 8 9 10 11 | brew search adoptopenjdk ==> Casks adoptopenjdk adoptopenjdk12-openj9-jre adoptopenjdk10 adoptopenjdk8 adoptopenjdk11 adoptopenjdk8 adoptopenjdk11-jre adoptopenjdk8-jre adoptopenjdk11-openj9 adoptopenjdk8-openj9 adoptopenjdk11-openj9-jre adoptopenjdk8-openj9-jre adoptopenjdk12 adoptopenjdk8-openj9-large adoptopenjdk12-jre adoptopenjdk9 adoptopenjdk12-openj9 |
似乎未标记的版本是Hotspot JVM版本，而带有openj9的版本是OpenJ9 JVM版本。
这次，我将安装AdoptOpenJDK11的OpenJ9版本，因为这很重要。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | brew cask install adoptopenjdk11-openj9 Updating Homebrew...

安装确认
1 2 | /usr/libexec/java_home -v 11 /Library/Java/JavaVirtualMachines/adoptopenjdk-11-openj9.jdk/Contents/Home |
JAVA_HOME，PATH设置
如果您是bash人，请像这样设置它。
1 2 | export JAVA_HOME=`/usr/libexec/java_home -v 11` PATH=$JAVA_HOME/bin:$PATH |
我用鱼，所以看起来像这样
1 2 | set -x JAVA_HOME (/usr/libexec/java_home -v 11) set -x PATH $JAVA_HOME/bin $PATH |
设置后，检查版本
1 2 3 4 5 6 7 | java -version openjdk version "11.0.3" 2019-04-16 OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.3+7) Eclipse OpenJ9 VM AdoptOpenJDK (build openj9-0.14.0, JRE 11 Mac OS X amd64-64-Bit Compressed References 20190418_204 (JIT enabled, AOT enabled) OpenJ9 - bad1d4d06 OMR - 4a4278e6 JCL - 5cc996a803 based on jdk-11.0.3+7) |
因此，似乎可以毫无问题地对其进行设置。
