在cmd中，执行启动命令行：

java -jar jenkins.war --httpPort=8080

报错信息如下：

5月 06, 2023 4:55:49 下午 Main verifyJavaVersion
严重: Running with Java class version 63 which is not in the list of supported versions: [52, 55, 61]. Run with the --enable-future-java flag to enable such behavior. See https://jenkins.io/redirect/java-support/
java.lang.UnsupportedClassVersionError: 63.0
at Main.verifyJavaVersion(Main.java:147)
at Main.main(Main.java:108)
Jenkins requires Java versions [17, 8, 11] but you are running with Java 19 from D:\JDK-19
java.lang.UnsupportedClassVersionError: 63.0
at Main.verifyJavaVersion(Main.java:147)
at Main.main(Main.java:108)

错误1：解决方案

根据提供的错误信息，您正在使用 Java 19，而 Jenkins 支持的 Java 版本为 8、11 和 17。为了解决此问题，您需要安装一个受支持的 Java 版本并将其设置为默认的 Java 版本。

1）安装JDK

下载并安装适合您操作系统的支持的 Java 版本（例如 JDK 8、11 或 17）。您可以从 Oracle 官方网站或 AdoptOpenJDK下载。

2）查看java版本

下载完成后，打开一个新的命令提示符窗口，运行以下命令以验证 Java 版本：

java -version

确保显示的版本与您安装的 JDK 版本相匹配。

3）重新启动 Jenkins

使用以下命令启动 Jenkins

java -jar jenkins.war --httpPort=8080

错误2：错误描述

在cmd中，执行启动命令行：

java -jar jenkins.war --httpPort=8080

报错信息如下：

错误2：解决方案（方法1）

从日志中可以看出，Jenkins启动失败的原因是端口冲突。错误信息显示：“Address already in use: bind”，表明8080端口已被其他程序占用。因此，Jenkins无法在8080端口上启动。

1）切换端口启动

在cmd中，使用8081或其他端口启动：

java -jar jenkins.war --httpPort=8082

2）浏览器查看

打开浏览器输入http://localhost:8082。可以看到Jenkins已经启动。

jenkins启动设置文件路径 jenkins启动报错_jar

错误2：解决方案（方法2）

1）关闭被占用的端口

查找并关闭占用8080端口的程序：使用以下命令查找占用8080端口的程序：
Windows:

netstat -ano | findstr :8080

Linux:

sudo lsof -i :8080

找到占用端口的程序后，结束相关进程，然后重新启动Jenkins。

2）浏览器查看

打开浏览器输入http://localhost:8080。可以看到Jenkins已经启动。
