执行war文件时安装Jenkins的问题

Question

我在Windows中使用Jenkins 2.73.1。当执行以下命令安装Jenkins时，

java -jar jenkins.war

我收到以下错误：

C:\Program Files (x86)\Jenkins>java -jar jenkins.war

有人可以帮忙吗？

Answer 1

好吧，我在您的堆栈跟踪中看到了一些似乎很可能引起问题的东西。值得注意的是这两个：

Exception in thread "Jenkins initialization thread" java.lang.NoClassDefFoundError: hudson/util/HudsonFailedToLoad
Caused by: java.lang.ClassNotFoundException: hudson.util.HudsonFailedToLoad

和

java.io.IOException: Failed to start Jetty
Caused by: java.net.BindException: Address already in use: bind

基本上，这里有两个问题，第一个是您的Jenkins试图绑定的端口已经在使用中，尝试弄清楚端口码头想要绑定的端口（通常是80或8080，如果我的记忆）。

第二个问题是，我认为它找不到试图抛出的异常的类。

我不确定怎么回事，我释放了端口，看问题是否消失了，如果找不到，为什么您的类路径中缺少该类
