完整元启动命令错误后修复，java版本问题

$ /opt/homebrew/opt/openjdk@17/bin/java -Dmail.smtp.starttls.enable=true -jar /opt/homebrew/opt/jenkins-lts/libexec/jenkins.war --httpListenAddress=0.0.0.0 --httpPort=8080
Running with Java 17 from /opt/homebrew/Cellar/openjdk@17/17.0.8.1/libexec/openjdk.jdk/Contents/Home, which is older than the minimum required version (Java 21).
Supported Java versions are: [21, 25]
See https://jenkins.io/redirect/java-support/ for more information.

$ /opt/homebrew/opt/openjdk@21/bin/java -Dmail.smtp.starttls.enable=true -jar /opt/homebrew/opt/jenkins-lts/libexec/jenkins.war --httpListenAddress=0.0.0.0 --httpPort=8080

brew start错误

$ brew services list
Name        Status   User File
jenkins-lts error  1 root ~/Library/LaunchAgents/homebrew.mxcl.jenkins-lts.plist

原因

brew services start jenkins-lts 生成的~/Library/LaunchAgents/homebrew.mxcl.jenkins-lts.plist 中的java 版本号是错误的

修改启动
/opt/homebrew/opt/jenkins-lts/bin/jenkins-lts

#修改生成文件的模版
/opt/homebrew/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist

问题

$ brew services start jenkins-lts
Bootstrap failed: 5: Input/output error
Try re-running the command as root for richer errors.
Error: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/jing/Library/LaunchAgents/homebrew.mxcl.jenkins-lts.plist` exited with 5.

# 
$ brew services list

$ brew services stop jenkins-lts
$ brew services start jenkins-lts
