jenkins更新错误：java.net.BindException：地址已在使用中

Question

如果有人告诉我我在这里想念的内容，而不只是拒绝投票，那将是非常好的。这是整个SO矩阵的真正缺陷。

我刚开始接触詹金斯（Jenkins），并且正在尝试更新。

仅供参考，我已经读过这篇文章：无法启动詹金斯

我也尝试过这样的方法：http : //www.ramk.io/2014/06/updating-jenkins-ci-server-on-mac-os-x/

即使Jenkins是唯一在8080端口上运行的设备，我也遇到了问题。

我尝试运行时的完整错误：

java jar jenkins.war

我得到这个堆栈跟踪：

正如我提到的，我尝试检查8080上还运行了什么：

sudo lsof -i :8080
COMMAND PID    USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
java    810 jenkins  156u  IPv6 0x2e7be7a88f4bb833      0t0  TCP *:http-alt (LISTEN)

Answer 1

我能够通过杀死活动监视器中正在运行的 java 进程来解决这个问题。您可以尝试以下操作：

1. 启动活动监视器
2. 搜索 java
3. 选择正在运行的java进程，点击窗口右上角的（X）按钮杀死它
4. 启动詹金斯服务器

Answer 2

尝试使用以下命令运行jenkins：

java -jar jenkins.war --httpPort=XXXX

其中XXXX与默认端口8080不同的端口
