Required: openjdk@11 ✔
==> Caveats
Note: When using launchctl the port will be 8080.

To restart jenkins-lts after an upgrade:
  brew services restart jenkins-lts
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/openjdk@11/bin/java -Dmail.smtp.starttls.enable=true -jar /usr/local/opt/jenkins-lts/libexec/jenkins.war --httpListenAddress=127.0.0.1 --httpPort=8080

②、/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formulaに移動

③、git log --oneline jenkins-lts.rb バージョン一覧を確認

④、以前のバージョンは動いていたので以前のバージョンを探して戻す

git checkout 3a3803f22e2 jenkins-lts.rb
brew unlink jenkins-lts
brew install jenkins-lts
brew services restart jenkins-lts
cd ~/Library/LaunchAgents
launchctl unload -w homebrew.mxcl.jenkins-lts.plist
launchctl load -w homebrew.mxcl.jenkins-lts.plist

むやみやたらに軽い気持ちでアップデートするとPlugin周りの整合性が取れずというところでした。
