我最近将 Jenkins 从 1.506 升级到 1.515

升级后，Jenkins 似乎没有启动。日志中充满了警告，例如：

WARNING: Failed to load hudson.scm.Cvs...
java.lang.InstantiationException: file:/jenkins/plugins/cvs/WEB-INF/classes/META-INF/annotations/hudson.Extension might need to be rebuilt: java.lang.ClassNotFoundException: hudson.scm.Cvs...

并且 Web GUI 无法访问（超时）。

我再次降级到 1.506，但结果相同。由于所有日志警告都与 CVS 相关（我不使用，我们在 svn 上），我尝试删除

/jenkins/plugins/cvs
/jenkins/plugins/cvs.jpi

但是它们在每次重新启动后都会回来，以及所有警告。

我在 Solaris 上运行的专用 tomcat 中运行 jenkins 作为战争。

现在，Jenkins 完全无法访问。任何指针表示赞赏！

下面是更大的日志片段。

我通过清除“工作区根目录”解决了这个问题。那是：

  • 阻止詹金斯
  • 移动工作区文件夹 (mv JENKINS_HOME/workspace JENKINS_HOME/workspace-old)
  • 创建新工作区 (mkdir JENKINS_HOME/workspace)
  • 重启詹金斯

我不知道是什么损坏了，或者如何损坏，但是这个解决方案似乎没有任何不利影响。根据 Jenkins 配置页面（Jenkins > 管理 Jenkins > 配置系统 > 单击主目录附近的高级按钮），工作区根目录用于“指定 Jenkins 将在主节点上存储作业工作区的位置”。

据我所知，它似乎只存储从 svn 签出的每个作业的文件，这些文件显然很容易替换。

无论如何，现在一切都重新开始了。升级第二次运行良好。
