1、删除homebrew目录下面的homebrew-cask 和homebrew-core ，重新下载这两个部分。
2、设置清华的homebrew源
四、编译server模式的 hotspot??jvm
一、编译环境
macOS bigSur 11.5+Xcode +command Line tools?
openjdk12 源码zip包：https://hg.openjdk.java.net/jdk/jdk12/file/06222165c35f
二、编译出现的问题
Error: git: Calling `sha256 "digest" => :tag` in a bottle block is disabled!
Error: git: Calling `sha256 "digest" => :tag` in a bottle block is disabled! Use `brew style --fix` on the formula to update the style or use `sha256 tag: "digest"` instead.
Please report this issue to the homebrew/core tap (not Homebrew/brew or Homebrew/core), or even better, submit a PR to fix it:
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/git.rb:9
Error: autoconf: Calling `cellar` in a bottle block is disabled!
brew install autoconf

三、解决方法
1、删除homebrew目录下面的homebrew-cask 和homebrew-core ，重新下载这两个部分。
2、设置清华的homebrew源

四、编译server模式的 hotspot??jvm
mbp-4:Downloads storm$ cd jdk12-06222165c35f
mbp-4:jdk12-06222165c35f storm$ bash configure --enable-debug --with-jvm-variants=server
configure: (Your Boot JDK version must be one of: 11 12)
configure: Found potential Boot JDK using well-known locations (in /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk)
configure: Potential Boot JDK found at /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home is incorrect JDK version (java version "1.7.0_79"); ignoring
configure: (Your Boot JDK version must be one of: 11 12)
configure: Could not find a valid Boot JDK. You might be able to fix this by running 'brew cask install java'.
configure: This might be fixed by explicitly setting --with-boot-jdk
configure: error: Cannot continue

在周志明《深入理解java虚拟机 JVM高级特性与最佳实践 第三版》这本书中，用的是openJDK11.0.3做的默认的jdk，我电脑里只有jdk1.7 和jdk1.8，我下载一个 jdk11.0.12,再次编译成功。
