Jenkins hudson.util.IOException2:远程文件操作失败

Question

我使用的是CentOS 5和Jenkins 1.430。当我尝试构建时，我得到一个错误：

这个帖子似乎说主从机出了问题：https://groups.google.com/forum/?fromgroups=#!topic/jenkinsci-issues/MaMqjK3iW8Y

但它并没有真正提供一个解决方案。Jenkin slave说它是连接的，并反映在Jenkins项目页面上。

Answer 1

显然，禁用从属程序并重新启动它是有效的。什么都没有

Answer 2

如果您不想重启，那么只需在从服务器上终止这些进程

$ ps -ef | grep java
1006     11948 11930  0 Jul17 ?        00:00:00 bash -c cd "/mnt/jenkins" && java  -jar slave.jar
1006     11949 11948  0 Jul17 ?        00:02:55 java -jar slave.jar

然后再次启动从代理

Answer 3

我得到了一个非常类似的错误，并通过将"publish over ssh“插件从1.14恢复到1.13来修复它

我们的Jenkins服务器运行在Debian 8.2 (Jessie)上，而我们的slaves运行在Ubuntu 14.04 (trusty)上。
